“ These Grandmas Drove Me Mad . It Was Brilliant ! ” — Promising Starting Points to Support Citizen Competence for Sustainable Consumption in Adults

The article addresses citizen competence for sustainable consumption in adults. It discusses whether it is possible to develop educational offerings for adults (being by nature short and isolated) that effectively promote this competence and whether it makes a difference if sustainable consumption is approached by focusing on good life (quality of life) and justice or by focusing on natural resources and environment (as is suggested by, e.g., environmental literacy approaches). Taking the case of energy policy, it presents an educational intervention (EdIn) developed, implemented, and investigated by the authors. In data-analysis, three approaches were adopted (methodological triangulation), one analysing the deliberations’ cognitive structure, one analysing the participants’ perception, one analysing the participants’ reaction (in terms of the knowledge/concepts and values/concerns they voiced). The results show, firstly, that the didactical design of EdIn was successful with a view to supporting citizen competence in participants. Secondly, they show that in adult civic education sustainable consumption should be approached by focusing on good life and justice. Thirdly, they indicate that people do not necessarily perceive themselves to be part of societal decision-making, leading from the question of the design and content of civic educational activities to the question of their necessity.


Introduction
It is broadly accepted both within and outside academia that sustainability in consumption will not be achieved by relying on technical solutions only and that it will only be achieved if consumer behaviour changes as well (e.g., References [1][2][3][4] to name just a few).This refers to individuals in their role as consumers and it calls for policies supporting or initiating this change of behaviour.The latter, in turn, involves individuals in their role as citizens, because designing and deciding about policies for sustainable consumption is not (and cannot be) confined to governmental bodies, politicians, and technical experts (e.g., [2,3,[5][6][7][8][9]).We proceed, thus, from two basic assumptions.The first is that sustainable consumption will not be achieved without fundamental transformations of consumption.The second is that inducing fundamental changes in consumption is neither the sole responsibility of in Section 1.2.1 allow us to infer criteria activities of civic education have to meet: Activities of civic education must themselves comply with the conditions mentioned above, that is, they should allow for interaction and collective action in their design, they should create an atmosphere that fosters mutual understanding and trust, and they should ensure a diversity of participants and provide for neutral facilitation.
This understanding of citizen competence and its consequences for corresponding educational offerings is in line with, and part of, most approaches in education for sustainable development for children and youths (e.g., [39][40][41]).What is, however, basically neglected in the scholarly debate about education for sustainable development (an exception is, e.g., Reference [31]) is the problem of how to provide educational offerings for adults targeting this kind of citizen competence for sustainable consumption.
Designing and implementing such offerings for adults has to deal with some specific challenges (e.g., [31]): To be inclusive, such offerings have to be rather short and consider restraints in terms of the time people can and are ready to invest in attending them.This sets limits with a view to the possibilities of going into details and leading in-depth discussions.Such offerings are optional, that is, there is no guarantee that someone attends more than one offering.As a consequence, each offering must be conceived as an isolated and single offering, and this in turn does not allow to draw on anything that has been or will be done and achieved in another educational offering; it is, in other words, impossible to adopt a curriculum perspective in the design of such offerings.
These challenges are considerable and raise the question of whether it is possible to promote citizen competence for sustainable consumption of adults by educational offerings and how such offerings should be designed (with a view to both didactics and content) to comply with the abovementioned conditions and to meet the outlined challenges.This is the question we address in this paper.
The paper is structured as follows: In Section 2, we describe an educational intervention we designed and implemented to investigate this question.In Section 3, we present the data we produced and how we approached data analysis, and in Section 4, we show our results.In Sections 5 and 6, we discuss what can be achieved by such an educational offering, and we draw conclusions with a view to the implementation of educational offerings targeting the promotion of citizen competence for sustainable consumption in adults.

Design of the Educational Intervention (EdIn)
In a project funded by the Swiss National Science Foundation (SNSF) (this research project was funded by the SNSF as part of its National Research Programme (NRP) 71 "Managing Energy Consumption" (2015-2017).Project title: "Towards societal consensus-Influencing the perception and evaluation of energy policy measures by means of self-reflection and information".Project team: Rico Defila (attorney at law, co-leader), Antonietta Di Giulio (philosophy, co-leader), Patricia Holm (biology, co-leader); Philipp Hirsch (biology, research associate), Corinne Ruesch Schweizer (educational sciences, research associate).We realised an educational intervention (EdIn) aiming to foster citizen competence for sustainable consumption in adults.Due to the context in which the research was funded, EdIn focused on energy policy (in Section 5.4, we address its applicability in other fields of consumption policy).In this section, and proceeding from what has been outlined in Section 1, we justify and describe the guiding principles and the specified goals as well as the content and the structure of EdIn.

Specified Goals and Guiding Principles of EdIn
The specified goals of EdIn correspond to the understanding of citizen competence in the context of sustainable consumption that we explained in Section 1.2.2.The principles guiding the design of EdIn are drawn from the conditions that activities of civic education must comply with that we described in the same section and from the theory of teaching and learning that we adopted.In terms of teaching and learning theories, EdIn is based on a constructivist approach (e.g., [42,43]).According to such an approach, education is a process that cannot be determined by the teachers but has to be accomplished by the learners themselves, and education is not primarily about replacing falsities by truths but about broadening, diversifying, and refining the learners' perspectives.
With a view to the promotion of citizen competence, EdIn should promote the participants' abilities in assessing and developing energy policy options, in engaging in deliberation and consensus-building about energy policy, and in individual, mutual, and collective learning and reflection about perspectives in their relation to energy policy.With a view to its didactics, EdIn should draw primarily on the participants' perspectives and allow for discussion and reflection leading to a broadening of these perspectives, and it should be characterised primarily by face-to-face discussions and activities of participants.
EdIn should provide participants with the opportunity to acquire new (scientific) information and to use this information as a basis to reflect their own perspectives.Accordingly, presentations by the facilitators had to be part of EdIn, but these presentations should be as short as possible.They should be tailored to support reflection and discussion, and they should not aim at conveying as much information as possible.After each presentation, a moderated discussion should allow to link the content of the presentation to the participants' perspectives, that is, each presentation should end with an appropriate stimulus, and each discussion should be initiated with a question inviting participants to voice their own knowledge and experiences and to formulate questions and considerations.These discussions should also be a substitute to a serious beforehand investigation into participants' perspectives (knowledge/concepts, values/concerns, experiences) not being possible for this kind of short and isolated educational offering.
EdIn should provide participants with the opportunity to apply what they would hear and discuss and to draw their own conclusions from that.Therefore, EdIn should not present participants with final solutions to the 'energy issue' or with a set of criteria to apply in assessing energy policies but invite them to develop, justify, and apply suitable criteria by themselves.This should encompass interaction, thus providing the participants with the opportunity to exchange and compare perspectives.At the same time, it should simulate a political deliberation about policy measures aiming at consensus.In order to avoid the impression that the facilitators are assessing the participants, and in order to make it easier for those participants that do not feel comfortable if they have to speak in public to voice their opinion, this collective action should take place in small working groups and not in the plenary.However, the results of these discussions should be presented and discussed in the plenary to allow for comparisons, and these presentations should in turn be the basis for an overarching discussion about energy policy.An abstract development and discussion of criteria is at least difficult and might, depending on their cognitive competences, be even impossible for some of the participants.Because of that, participants should be provided with a selection of policy measures targeting or affecting consumer behaviour they should use as a case for application.These measures, in turn, should be actually discussed in Switzerland, and for that reason, we decided to choose them from the 182 measures mentioned in the different documents building the Swiss "Energy Strategy 2050".
A constructivist approach to teaching and learning has implications not only on didactics, but also on the content of educational offerings.It implies that the content of an educational offering should be constructed by integrating the relevant scientific perspective(s) on the topic and the learners' perspectives on the topic to allow for effective learning (see, e.g., the "Model of Educational Reconstruction" [43]).In more general terms, this requires that the learning content of educational offerings links to the perspectives of those addressed by the educational offering (in our case, this is the perspective of individuals in their role as citizens).
The topic energy policy can be approached from different angles leading to different possible contents of an educational offering, and with a view to sustainability, the most important ones are environmental issues and issues of good life and justice.Taking environment as a focus in the education of adults is quite prominent in the literature.It is often assumed that the problem of policies not being broadly accepted or not being effective is caused by a lack of environmental literacy (or energy literacy) in individuals.The natural conclusion is that it is necessary to increase this literacy by educating individuals about environmental issues and/or technical solutions to environmental (or energy) problems (e.g., [9,17,18,44,45]).Taking good life and justice as a focus is in turn not advocated by scholars with a view to educating individuals.However, several scholars point out the importance of issues of human well-being with regard to assessing policy options and with regard to policy support and conclude that a discussion on quality of life might be a possible starting point to tackle change toward sustainable consumption (e.g., [21,46]).Our own research [13] shows, firstly, that how energy policy measures impact on human well-being and social justice is crucial to both the consumer perspective and the citizen perspective.With regard to environmental issues, it shows, secondly, that although people do not attach much importance to natural resources from a consumer perspective, environmental protection as an outcome of energy policy measures seems to be important to people from a citizen perspective.Hence, both foci could provide a suitable content for an educational offering targeting citizen competence for sustainable consumption of adults.
We wanted to find out whether we can identify any differences between an educational intervention focusing on the content of good life (and the impacts of policy measures on the quality of life and justice) and one focusing on the content of natural resources (and the environmental impacts of policy measures).What interested us most was the question of whether one or the other connects more to the perspectives of individuals in their role as citizens and is, thus, more suitable to support the development of citizen competence.For this reason, we needed two versions of the same intervention, one informed by a good life perspective (the EdIn-GL) and one by a natural resource perspective (the EdIn-NR).These two should be applied in a quasi-experimental setting.
In designing EdIn, we adopted an interdisciplinary approach: In a first step, three members of the project team identified the didactical elements to consider in designing EdIn.In parallel, and depending on their research expertise and scientific background, two team members identified the core messages (premises and statements) to convey to participants with a view to the good life perspective, and two did the same with a view to the natural resource perspective.In a second step, the results of these three subteams were exchanged and discussed until reaching agreement within the team.In a third step, the didactical structure of EdIn was developed and, in a fourth step, the inputs (including the slides and examples as well as the stimuli concluding the inputs and the questions to initiate the discussions), the materials, the tasks for the working groups, and the rules on how to moderate the discussion were elaborated on and discussed in the team until reaching agreement.

The Core Messages to Convey in EdIn-GL and the Stimuli in EdIn-GL
To develop the core messages and stimuli for EdIn-GL, we drew on research about how sustainable consumption and good life (not in a moral sense but in terms of quality of life) relate [26,47].We arranged the core messages and stimuli in two packages as follows: Package one starts from the premise that humans want to lead a good life, that is, a life they value (premise 1).It comprises the following statements (statements 1-4):

•
Statement 1: Humans do not want to consume energy.Rather, they want to satisfy needs and desires that specify their conceptions of a life they value, and the acts of consumption they perform serve the purpose of satisfying these needs and desires.Thus, consumption of energy is not an end in itself but a means to achieve specific purposes.

•
Statement 2: What individuals want (ends in themselves) has to be distinguished from the means they adopt to achieve these ends.With regard to the means, the acts individuals perform in order to satisfy their needs and desires must be distinguished from the consumer goods (products, infrastructures, services) they use in performing these actions.
• Statement 3: Quite often, individuals can satisfy their needs and desires by different means, that is, they can satisfy a specific need or desire by other means (other acts or other consumer goods) without impairing their quality of life.

•
Statement 4: Relevant to energy are not the needs and desires of individuals (the purposes), but the acts they perform in order to satisfy them, and the consumer goods they use in performing these actions, and these means, in turn, differ with regard to their relevance to energy.To assess this relevance, not an entire and connected chain of acts of consumption has to be assessed, but the single acts within this chain.
The stimulus that concludes package one is (stimulus 1): Means and ends in themselves must be distinguished, and it must be asked what from what individuals do is actually relevant to energy.
Package two starts from the following premise: Because all (non-)actions of individuals impact the life and actions of others, both the question of how quality of life and justice relate and the question what role this plays or should play in discussions about energy and energy policy are questions to be asked (premise 2).It comprises the following statements (statements 5-7):

•
Statement 5: Individual conceptions of a good life differ, but looking at the ends themselves instead of looking at the means reveals that, possibly, some of these ends are universals (making it necessary to distinguish universal needs from not universal desires).

•
Statement 6: The starting point to distinguish means from ends in themselves and to identify means being relevant to energy should be universal human needs.

•
Statement 7: The goal of sustainability is to ensure that each and every human being living now or in the future has the possibility of living a life he/she values.For this reason, reflecting on energy policy must always encompass reflecting on the quality of life we want to provide for humans living at the same place we do, for those living in other places, for those living now, and for those living in the future.Thus, it is necessary to consider how present individual and collective acts impact the possibility of others to lead a life they value.
The stimulus that concludes package two is (stimulus 2): This way of thinking raises a series of questions which are uncomfortable because there is no final answer to them: What world do we want to leave to future generations, what chances and what mortgages?How do our acts affect other humans-here, elsewhere on the world, now, in the future?When are our doings, as individuals and as society, just?How exactly do we define justice?

The Core Messages to Convey in EdIn-NR and the Stimuli in EdIn-NR
To develop the core messages and stimuli for EdIn-NR, we drew on research about the environmental impact of energy production and energy use [48,49].We arranged the core messages and stimuli in two packages as follows: Package one comprises the following statements (statements 1-2):

•
Statement 1: With a view to the pollution and to other forms of damage to natural resources and to the environment as well as to the overuse of natural resources, not only the energy use matters but also the energy source.Different energy sources such as fossil or nuclear sources differ with regard to their environmental impact, both at the place where the energy is produced and at the place where the energy is consumed.Because of this, discussions around energy have to consider the environmental impacts caused by the energy source and the transportation of energy as well.

•
Statement 2: With a view to a sound discussion around energy, grey energy (embodied energy, hidden energy) is as important to consider as the direct and operational (visible) energy use.
The stimulus that concludes package one is (stimulus 1): It is important to consider both the source of the energy that goes into consumer goods and the amount of grey energy hidden in consumer goods.

•
Statement 3: The energy use requires more environmental goods and natural resources than those that are used directly in the production of energy (in a narrow sense) and those that are used in the production of consumer goods (products, infrastructures, services).This encompasses both the use of environmental goods and natural resources as well as their pollution.These rather diverse impacts on environmental goods and natural resources all have to be taken into account when reflecting about energy and energy policy.

•
Statement 4: Producing renewable energy is not neutral with regard to its environmental impacts.That is, the production of renewable energy uses and impairs environmental goods and natural resources as well.
The stimulus that concludes package two is (stimulus 2): With a view to a reasonable and sustainable dealing with energy, both play a crucial role: The energy source as well as the energy use and with that the amount of energy that is consumed.

Structure of EdIn
Introduction: To get started, the participants and the facilitators introduced themselves (Table 1).This introduction was designed to be, at the same time, a first invitation to the participants to voice and share their individual energy-related perspectives.This invitation should be made as tangible and as low-threshold as possible, it should be as open as possible, it should avoid that participants venture into unfolding their declarative knowledge about energy and/or whether and how they make efforts to save energy (or felt forced to do so), and it should avoid that the participants start to worry about whether they are being tested.To achieve this, participants were provided with a selection of approximately 40 rather diverse images (mostly photographs), and this body of images encompassed both images that have to do with energy in the sense of energy policy as well as images that have to do with energy in various other everyday language contexts.Participants were asked to choose the image corresponding the most with the spontaneous image the term 'energy' evokes with them, and facilitators did the same.
The two main parts: Part 1 consisted of short presentations by the facilitators (core messages and stimuli from the good life perspective in EdIn-GL, core messages and stimuli from the natural resource perspective in EdIn-NR), followed by discussions serving the purpose of enhancing understanding of the presentations and of linking them to the perspectives of the participants (Table 1).The core messages and the stimuli were conveyed in colloquial language and mainly using a lot of examples tailored to daily life in Switzerland.In part 2, the participants reflected on the consequences of the good life perspective (in EdIn-GL) or the natural resource perspective (in EdIn-NR) on energy policy by developing and applying criteria they perceived to be adequate to assess policy measures in a way that is consistent to these perspectives in working groups.These criteria were presented and discussed, and this, in turn, led into an overarching discussion about energy policy (Table 1).
Feedback: At the end of an educational offering for adults, participants are, as a rule, explicitly asked about their learning outcomes.This reflection can be combined with asking participants to give feedback on content and didactics.Because we wanted to get explicit feedback to EdIn from the participants, we refrained from asking them explicitly about their learning outcomes but focused on asking them explicitly how they had experienced EdIn (Table 1).

Introduction
The participants and the facilitators introduced themselves by explaining their choice of image.

Discussion of presentation I (20')
The participants were asked an initiating question they discussed in pairs.The reports by these groups informed the subsequent discussion in the plenary.
EdIn-GL: How can we distinguish between wants of individuals and the means they use to satisfy their desires and needs?EdIn-NR: What do we know about the grey energy of the products we use, and how much can we find out about it?Presentation II and discussion II Presentation II (10') In EdIn-GL, the presentation covered premise 2, statements 5-7, and stimulus 2. In EdIn-NR, the presentation covered statements 3-4 and stimulus 2.

Discussion of presentation II (20')
The participants were asked an initiating question they discussed in the plenary.
EdIn-GL: The freedom to choose and implement one's own lifestyle ends where it impairs the quality of life of others: Which others must be considered, that is, how far does our obligation reach?EdIn-NR: The participants were provided with a list of six energy policy measures (each described in 2-3 sentences).They were asked to, firstly, identify measures they found particularly convincing (or particularly unconvincing) against the background of what had been presented and discussed before coffee break and, secondly, to name the criteria they had used in this selection.Presentation of working groups' results and discussion (40') In a first step, the working groups presented their results, and these results led, in a second step, to an overarching discussion about energy policy.

Feedback
The participants were asked what they had found more or less interesting, what should be changed and what should be retained.They answered in the plenary, but no-one was forced to answer the question.

Methods Applied in Analysing the Data
EdIn was embedded in an empirical design that was larger in scope and sample than EdIn and consisted of two rounds of seminarrative (individual) interviews with 48 respondents, one round before and one after EdIn.The aim of these interviews was to uncover how individuals perceive (future) energy policy measures in their role as consumers and in their role as citizens (for more details and the results, see Reference [13]).
In the first part of the interviews in round one, we addressed respondents in their consumer role (anticipation of impacts of measures on their own lives), and in the second part, in their citizen role (consenting to or rejecting measures).Each respondent was assigned one out of three energy policy measures.In the second round of interviews (approx.one year later), each respondent was provided with the reprocessed results of the first interview with him/her.This second round of interviews served the purpose to ascertain whether in analysing and interpreting the data, we would have to consider major changes in the perception and judgement of the respondents.Those out of the respondents that had participated in EdIn were asked for feedback on EdIn (the supplementary question was whether they had, looking back on the discussion, any comments on the discussion).
EdIn took place in between these two rounds of interviews, that is, approx.eight months after round one and five months before round two.In this section, we present the participants of EdIn (recruitment and sample), the data we produced, and how we approached data analysis.

Recruitment of Participants and Sample
The sample for our project was built by quota (the characteristics of quota sampling being gender, age, educational level, place of residence) and consisted of 48 respondents.The quota of each characteristic in the sample (Table 2) matches the distribution in the Swiss population (aged 20 and older).The single characteristics have been independently calculated.To recruit participants for EdIn, we invited all of our 48 respondents to attend a "discussion about energy policy" lasting four hours (one 15-19 pm, the other one 16-20 pm).They were offered two dates (both were weekdays) out of which, if they wanted to accept the invitation, they could choose one suiting their availability (that is, it was their availability that decided to which of the two EdIns they were assigned).Those that had accepted our invitation knew that two such discussions would take place, but they knew neither that these discussions would differ with regard to the content serving as a starting point to approach the topic of energy policy nor what the exact content would be in the discussion they would attend.
EdIn did not take place at the University of Basel (placed at the northern end of Switzerland) but in the railway station in a city that in Switzerland is perceived to be the 'neutral place' to meet for people coming from different parts of the country (and providing rooms for a broad diversity of gatherings).All the same, both the duration of the discussion as well as the necessity to travel to another place were considerable obstacles for people to participate.Thirteen respondents attended EdIn (Table 3), six of them attended EdIn-GL, and seven EdIn-NR.

Data Analysis
How EdIn was executed is shown in Section 2.3.The question we wanted to investigate was (see above, Section 1.2.2) whether it is possible to promote citizen competence for sustainable consumption of adults by educational offerings and how such offerings should be designed (with a view to both didactics and content).The analysis of the body of data should allow to compare EdIn-GL and EdIn-NR.The entire EdIn was tape-recorded (except for the discussions in the working groups) and transcribed (with a simple transcription system cf.[50]).The working groups wrote the criteria they used in their identification of particularly good or poor measures on cards that they then presented in the plenary (see Table 1), and these cards were photographed.Additional data were the answers to the feedback question in the second round of (individual) interviews with those that had participated in EdIn.These answers were also tape-recorded and transcribed.We adopted three approaches to analyse the body of data (the transcripts and photographs): • Approach 1 focused on the cognitive structure of the deliberations, that is, on how the discussions evolved in terms of the issues that were raised, the arguments that were developed, and the topics that were taken up or not during the discussions (analysed data: Part 1 discussions, part 2 presentations (transcripts and cards), part 2 discussions).

•
Approach 2 focused on the participants' perception of EdIn, that is, on how they experienced the setting and the discussions and on what they had, according to their own perception, learned (analysed data: Answers to feedback questions at the end of EdIn and during the second round of interviews).

•
Approach 3 focused on the participants' reaction to EdIn, that is, on how they reacted to the stimuli and the discussions in terms of the kinds of individual knowledge/concepts and values/concerns they voiced (analysed data: Part 1 discussions, part 2 presentations (transcripts), part 2 discussions).
These approaches cover, firstly, different and complementing aspects, both with a view to citizen competence as it is defined in Section 1 and with a view to the requirements that activities of civic education should meet in their design that are outlined in Section 1.Secondly, they represent a systematic interdisciplinary methodological triangulation leading to a broader and more differentiated understanding of EdIn.By adopting these three approaches, we took on several and complementing perspectives on EdIn and applied them equally and consistently in their respective logic.With reference to the terminology provided, for instance, by Flick [51], approach 1-the investigation of the interactively produced cognitive process in EdIn-corresponds to a structural perspective, while approach 2-the investigation of the meanings (incl.perceived learning outcomes) attributed to EdIn by the participants-corresponds to a meaning-related perspective.Additionally, we chose approach 3-the investigation of the individually produced cognitive reactions-to provide for a complement to approach 1.In implementing these approaches, we not only drew on different disciplinary approaches but also analysed multiple types of data [51].

Approach 1-Analysing the Cognitive Structure
This analysis focused on the content of the deliberations, that is, the entire discussions and the entire presentations (part 1: Two in EdIn-GL and two in EdIn-NR; part 2: Two in EdIn-GL and two in EdIn-NR) were each considered as a text, as an object to be examined with a view to its content and cognitive structure (see, for this kind of analysis, the contributions, for instance, in Reference [52], especially [53]).In this approach, the epistemological interest applies to the text itself, not to the persons who have produced it.The analysis has been done by applying a philosophical approach of analysing texts to a text not being an artificial text, that is, to a text that is not authored, but that is yet treated as one artefact.This kind of analysis is based on the hermeneutical assumption that the artefact subjected to the analysis is meaningful in a cognitive sense and that this meaning can be detected.In the first step of the analysis, summaries of the content were produced, and these summaries were tagged according to the speech act they represent (see Table 4 for the tagging categories).To enhance credibility of the analysis, we used the strategy of rater triangulation by validating the summaries and the tagging and discussing differences in summarising the content and in tagging speech acts until achieving consensus.Table 4. Analysing the cognitive structure of EdIn (part 1): Categories used to tag the speech acts performed during the discussions in part 1 of EdIn.

Tagging Categories
Tagging Rules

Affirmation
Content is an explicit affirmation (or a repetition) of a previously uttered content by the same person.
Answer/reaction Content is clearly an answer to a question asked or an objection raised.

Applicationown life
Experiences and examples taken from the own life ("I", my family, my housing estate etc.).

Broadening
Content is an explicit broadening of a previous content.

Broadening focus
Content broadens the focal content of the EdIn-perspective (good life in EdIn-GL, natural resources in EdIn-NR) by introducing an aspect that according to an expert's opinion does not directly relate to this focus.

Conclusion
Content is a conclusion drawn from previous statements.

Confirmation
Content explicitly confirms a statement, a further consideration, a conclusion etc. uttered by another person (in case of doubt, that is, in cases where a statement is similar to a previous but without explicitly referring to this previous statement, the new statement is not tagged as confirmation but tagged as "bis").

Correction/objection
Content is an explicit correction or objection to a previous statement.

Further consideration (FuC)
Content is, according to an expert's opinion, a consideration carrying forward, by advancing either the content of the moderators' presentation or other contents that have been uttered until then.Content is tagged as further consideration only if it represents a coherent and meaningful further development of the focal content of the EdIn-perspective (good life in EdIn-GL, natural resources in EdIn-NR), that is, if it is in line with this focus (otherwise the content is a broadening of the focus, even if it comprehensibly/meaningfully draws on preceding contents).

Query
Content is an explicit query about something that has been said before.

Recourse
Content is an explicit recourse to previous content (e.g., to examples).
This first step resulted in a diachronic representation of the discussions.In the second step, this diachronic analysis was translated into a flowchart representing only the cognitive structure of the deliberations and ignoring their temporal development.The cognitive structure shows the contents that were produced and the cognitive purpose they served, and it shows whether and in what kind of cognitive act they were taken up at some other point in the discussion by participants and facilitators.

Part 2: Application of the Perspective GL (EdIn-GL) or NR (EdIn-NR) to Energy Policy
The analysis of the transcripts of part 2 of EdIn proceeded from a synchronic approach.It was informed by the following questions: (a) What criteria were applied by the working groups (criteria, used primarily to assess single policy measures)?(b) What additional criteria did arise during the subsequent discussions (criteria, used primarily to assess single policy measures)?(c) What topics/questions were discussed with a view to energy policy (topics, not used to assess single policy measures)?
In the analysis, highly aggregated summaries of the content were produced, and these aggregated summaries were tagged according to whether they represent criteria or topics (see Table 5 for the tagging categories; subcategories served the purpose of further refining the tagging).To enhance credibility of the analysis, we used the strategy of rater triangulation by validating the summaries and the tagging and discussing differences in summarising and tagging the content until achieving consensus.Additionally, the stimuli and the information provided by the moderators were described and tagged in order to distinguish the contents that were produced without the moderators' intervention from those that were produced as a reaction to the moderators' intervention.
Table 5. Analysing the cognitive structure of EdIn (part 2): Categories and subcategories used to tag the summaries of the contents produced by the participants in part 2 of EdIn.

Tagging Categories
Tagging Rules

Criterion
Features used by participants to assess single energy policy measures (or even energy policy taken as a whole), regardless of whether they were explicitly declared as criteria by the participants themselves.
Topic Aggregated description of contents that were discussed by participants but were not directly used to assess policy measures.

Discussion
Aggregated description of contents that were discussed by participants either in the context of ventilating and/or applying a criterion or in the context of ventilating a topic.

Judgement
Aggregated description of opinions by participants that either met with approval or were not contradicted by others about what is the case or should be the case with regard to a specific topic.

Measure/indicator
Aggregated denotation of what was used by the participants to assess whether a criterion is met or not.

Problem
Aggregated description of facts and circumstances participants classified to be problematic with regard to a topic or with regard to a criterion, regardless of whether these facts and circumstances are accurate.

Question
Aggregated denotation of real questions that were raised in discussing a criterion, a topic, a specific policy measure, regardless of whether a question deals with factual issues (what is the case?) or with issues of evaluation (how should something be valued?).
This analysis resulted in a synchronic summary of the presentations and discussions, listing the criteria that were produced and used by the participants to assess energy policy measures and the topics/questions they subsequently discussed.

Approach 2-Analysing the Participants' Perception
This analysis focused on how the participants experienced the setting and the discussions of EdIn and on what they had, according to their own perception, learned.In the first step of the analysis, the transcripts of the answers to the feedback question at the end of EdIn and the transcripts of the answers to the feedback question during the second round of (individual) interviews were analysed by inductively developing categories that were then used to encode the single statements (see Table 6 for the categories).Technically, this was done using the data analysis software MAXQDA.In the following steps, the text passages assigned to a category were generalised and reduced according to the rules of a summary qualitative content analysis (cf.[54]).In order to validate the result of each of these steps, we used the strategy of rater triangulation and discussed differences in aggregating the data until achieving consensus.This analysis resulted in findings about how the participants perceived and experienced EdIn.

Individual motivation
Statements in which something is said about someone's motivation to attend EdIn and to partake actively in the discussions.Statements in which it is said that someone found it interesting, exciting (or similar) without indicating a learning effect.

Approach 3-Analysing the Participants' Reaction
This analysis focused on how the participants reacted to EdIn in terms of the kinds of individual knowledge/concepts and values/concerns they voiced.In this approach, the epistemological interest applies to the types of knowledge/concepts and values/concerns by which participants approached the topic, and not to the exact content of their statements.In the first step of this analysis, the transcripts of the discussions in part 1 of EdIn and of the presentations and the discussions in part 2 of EdIn were analysed by inductively developing a category system by means of a qualitative content analysis (cf.[54]) that was then used to encode the single statements (see Table 7 for the categories).Technically, this was done using the data analysis software MAXQDA.To enhance credibility of coding, we used the strategy of rater triangulation and discussed differences in coding until achieving consensus.In the second step of the analysis, these categories served as comparative dimensions.This way, for each of the parts of EdIn, we identified which types of knowledge/concepts and values/concerns were voiced at least once.

Approaching topic by voicing values
Statements in which something is said about what someone thinks is important, good or bad or about the criteria to be used in taking decisions.

Assessing acts
Statements valuing a specific behaviour as good or bad."I think that taking four flights per year is untenable and completely unjustified."(EdIn-GL/162)

Categories Coding Rules and Examples
Ascribing values

Environment-related values
Statements ascribing a value to a specific issue/fact/idea because this issue/fact/idea is described to be valuable with a view to the natural environment and/or statements in which environment-related values are the object of reflection."I think, the damage one brings about to the entire environment with producing energy is extremely important.This is an important aspect."(EdIn-GL/116)

Human-related values
Statements ascribing a value to a specific issue/fact/idea because this issue/fact/idea is described to be valuable with a view to humans and/or statements in which human-related values are the object of reflection."But, actually, it would be much more just to oblige all homeowners to do that.The cognitive structure of the discussions taking place in part 1 of EdIn shows the contents that were produced and the cognitive purpose they served, and it shows whether and in what kind of cognitive act they were taken up at some other point in the discussion by participants and facilitators.The analysis of the data resulted in flowcharts representing only the cognitive structure of the deliberations and ignoring their temporal development (see above, Section 3.2.1).In total, four flowcharts were produced, two for EdIn-GL (Figure 1) and two for EdIn-NR (Figure 2), one representing discussion I and one representing discussion II.
acts.With a view to the overarching research question, neither the single examples provided by the participants (or those recalled to mind by them) nor the arguments used to confirm or object to statements nor the content of queries are of particular importance.For this reason, in the graphs, some of the speech acts are represented only by an object that reduces the content of all statements belonging to them to the speech act itself.This applies to the participants' speech acts "application own life", "application generalised", "confirmation", "correction/objection", and "recourse" (objects in grey in the flowcharts).The speech acts "broadening", "broadening focus", "conclusion", and "further consideration" (FuC), in turn, are unfolded insofar as, in the graphs, each further consideration, conclusion, etc. is represented by a separate object.The number of arrows targeting at and/or originating from an object shows this object's cognitive importance in the discussion.An object that is not the starting point of an arrow was not referred to in the discussion after someone set it.The same applies to an object that is not targeted by an arrow originating from an object representing a confirmation or a correction/objection. Tracking the arrows originating from an object allows to recognise the speech acts it caused, and in the case of the speech acts confirmation and correction/objection, it allows to recognise what was confirmed and objected to.In the case of "further considerations", "conclusions", "broadening", and "broadening focus", it also allows to recognise which content led to them and /or which content caused which kind of reaction.The Cognitive Structure in Part 1 of EdIn-GL  The graphs (Figure 2) show that after both presentations, participants applied the presented contents to their own experience (examples drawn directly from their own daily life or examples drawn from how they perceive their social environment).In the discussion, they referred to the examples provided by the moderators as well, that is, the examples provided by the moderators played an equal important role as those provided by themselves or by other participants.They used their own experiences, those of other participants, and the examples of the moderators to develop further considerations and conclusions in which they unfolded the content given in the presentations.They also used these examples to support, confirm or correct further considerations and/or conclusions by other participants.

The participants developed a number of further considerations (FuC-P1 to FuC-P15) and they drew a number of conclusions (conclusions P1-P5) from what they had heard and reflected, and the moderators uttered objections or corrections only to two of these considerations (broadening P FuC-P13, FuC-P15) and to one of these conclusions (conclusion P5).During the discussion, participants referred to ten of the further considerations developed by other participants (the exceptions are FuC-P6, FuC-P7, FuC-P9, FuC-P11, FuC-P15), and to two of the conclusions (conclusions P1, P5), and they explicitly confirmed some further considerations that were stated by other participants (FuC-P1, FuC-P2, FuC-P8, FuC-P13, broadening P FuC-P13).Some of the further considerations did not emerge from examples but from previous further considerations or conclusions (FuC-P4, FuC-P6).Hardly any further consideration or conclusion was controversial; participants objected only to two of the further considerations voiced by other participants (FuC-P10, FuC-P12) and to one conclusion (conclusion P5).
Participants explicitly confirmed three of the statements by the moderators (statements M1, M3, M6), and they used one of the statements of the moderators (statement M4) as an argument to object to something that was said by the moderators.The only objection that was voiced was an objection to the relevance of the entire setting (leading to conclusion P5 and broadening focus P3), and this objection was criticised by other participants.
Participants left the given focus on good life by introducing three topics not corresponding to this focus (broadening focus P1-P3), and out of these three topics foreign to the focus, only one was taken up in the further discussion (broadening focus P3) by other participants, and this uptaking was an objection.Two topics foreign to the focus on good life that were introduced by participants (broadening focus P1 and P2) relate to environmental issues (relevance of energy source and grey energy), and these topics were not taken up in the discussion.
The dynamic of the discussion was mainly sustained by the participants; there was not much intervention by the moderators.

The Cognitive Structure in Part 1 of EdIn-NR
The graphs (Figure 2) show that after both presentations, participants applied the presented contents to their own experience (examples drawn directly from their own daily life or examples drawn from how they perceive their social environment).In the discussion, they referred to the examples provided by the moderators as well, that is, the examples provided by the moderators played an equal important role as those provided by themselves or by other participants.They used their own experiences, those of other participants, and the examples of the moderators to develop further In both EdIn-GL and EdIn-NR, the working groups consensually identified policy measures they found particularly convincing (or unconvincing) and developed and named criteria they had used in their assessment.
The working groups in EdIn-GL produced and used ten criteria in total.Out of these criteria, four criteria strongly relate to the focus of EdIn-GL (justice and three aspects of quality of life) and one does so to a lesser extent, because it refers more to standard of living than to quality of life (housing comfort).Three criteria relate to the environment and two to policy-making.Working group 2 in EdIn-GL pointed out that they had struggled with the question of how to weigh the dimensions quality of life and energy efficiency, and working group 1 emphasised that each measure has its pros and cons.The working groups in EdIn-NR produced and used eleven criteria in total.Out of these criteria, two criteria strongly relate to the focus of EdIn-NR (potential to save energy and light pollution).Two criteria relate to justice (one of them, justice, directly; the other one, impairment for individuals, indirectly), five to policy-making, one to the national economy, and one to society infrastructure.
Four of the criteria used by the working groups are identical in EdIn-GL and EdIn-NR (potential to save energy, justice, costs of implementation, effectiveness of measures), five if the criterion impairment for individuals (EdIn-NR) is taken to be similar to housing comfort (EdIn-GL).None of the criteria, neither in EdIn-GL nor in EdIn-NR, puts the actual or potential impacts of a measure on the participants centre stage.All criteria are either oriented toward the common good or target the issue of policy-making in a general sense or other issues at the societal level.

The Cognitive Structure in Part 2 of EdIn: Overarching Discussions about Energy Policy
Table 9 shows the criteria that were used in the plenary discussions about energy policy following the working groups' presentations and the topics that were raised in these discussions (see Sections 2.1 and 2.3) in EdIn-GL and in EdIn-NR.In the plenary discussion in EdIn-GL, no additional criteria to assess energy policy measures were added, that is, the criteria used in this discussion were identical or only slight variants of those that had been used in the working groups.This applies to EdIn-NR as well, with one exception.This exception is the criterion grey energy, but the use of this criterion was caused by the moderators, who reminded the participants of this criterion several times.The effectiveness of measures as well as justice were criteria used in both EdIn-GL and EdIn-NR.Criteria related to the natural environment were no longer used in EdIn-GL, while one of them stayed present in EdIn-NR.
Of the four topics that were raised in the subsequent discussion about energy policy in EdIn-GL, two are in line with the criteria that were used, one deals with policy-making in a general sense (enforcing measures or finding majorities), and one deals with applying the good life perspective to energy policy.Of the five topics that were raised in the subsequent discussion about energy policy in EdIn-NR, one is in line with the criteria that were used, one deals with policy-making in a general sense (enforcing measures or finding majorities), one relates directly to the measures discussed in the working groups, and two are derived from the measures discussed in the working groups.In EdIn-NR, there was no discussion devoted to the application of the natural resource perspective to energy policy.Two of the topics were raised in both EdIn-GL and EdIn-NR.

In their answers to the feedback questions, the participants touched upon energy policy, the setting and didactics of EdIn, and upon the effects EdIn had on them (learning and behavioural impacts).Participants of EdIn-GL also addressed good life as a content to approach the topic of energy policy.
With regard to energy policy, the participants' feedback shows that they do not perceive energy policy to be something they can actually contribute to.Rather, energy policy, in their perception, is done only/primarily by politicians and other experts, it is strongly influenced by party politics, and it is characterised by nonfactual, undifferentiated, and confrontational debates (and it is often deterrently moralising).This applies to both participants of EdIn-GL and of EdIn-NR.The perception of energy policy, in turn, strongly influences not only the expectations of (potential and actual) participants, but also whether an invitation to attend a discussion about energy policy is appealing, as the following quote illustrates: "I thought: 'Huh?Energy policy: What does this mean?'.Because, actually, you are addressing people that do not have to know anything at all when it comes to energy policy.And as a matter of fact, I do not feel invited to such a discussion because I cannot contribute anything from a political point of view" (EdIn-GL/395).At the same time, a differentiated and controversial (but not confrontational) discussion about energy policy that is not biased with regard to party politics is highly appreciated.
With regard to the setting and didactics of EdIn, the participants both of EdIn-GL and of EdIn-NR uttered explicitly positive comments with regard to both the methodical design (in general and also with regard to the single elements, as, for instance, the introduction with images) and the diversity of perspectives (positions, opinions, life experiences), as the following quote illustrates: "My goodness!The things I said!These grandmas drove me mad.It was absolutely brilliant how you unleashed those people on each other.That is, all these different and also clashing opinions.But it was not at all a fight, it was just a conversation."(IN_NR/10:13).Participants of EdIn-NR also positively emphasised the diversity of perspectives in the team of moderators.The feedback answers show the importance participants attribute to both, a diversity of opinions that allows for comparison of perspectives and a neutral facilitation that does prevent the prevalence of the opinions and values of singular individuals or groups and does support individuals to freely voice their opinions and experiences.Participants of EdIn-GL pointed out that such a discussion is, at least to a certain extent, unusual and requires a careful didactical design supporting individuals in feeling at their ease.In their feedback, participants of EdIn-GL and of EdIn-NR stated that attending the discussion had broadened their perception of energy policy and that they had learned from the exchange with the other participants and from being confronted with their different perspectives.Participants of EdIn-NR highlighted that such a discussion enhances an appreciative perception of the positions, opinions, and personal circumstances of others.Participants of EdIn-GL and of EdIn-NR said that such a discussion can impact not only how people think, but also peoples' behaviour, with the difference that participants of EdIn-GL put a greater emphasis on political behaviour, while participants of EdIn-NR put a greater emphasis on consumer behaviour.With regard to the effects listed by participants, there is one conspicuous difference between EdIn-GL and EdIn-NR: While participants of EdIn-GL said that the discussion had enhanced their understanding of their role in energy policy and had allowed them to overcome feelings of helplessness, participants of EdIn-NR said that the discussion had led them to recognise that the energy problem can most probably not be solved, as the following quote illustrates: "I find the issue extremely difficult.Everybody has given a thought to it, and then you are convinced that what you think is pretty much the obvious way to see things.And then you recognise: No, others actually think different about the issue than you do.That's what fascinated me.But it also depressed me.Somehow, it is also a depressing issue because you recognise that it will never come to an end" (IN_NR/10:11).
The analysis and comparison of the feedbacks given by the participants of EdIn-GL and EdIn-NR reveals one major difference: While participants of EdIn-NR did not comment on the content chosen to approach the topic energy policy, those of EdIn-GL did so quite explicitly.They felt enriched on a personal level by the good life perspective, although, at the same time, they stated the unusualness of The presentations of the working groups' results in part 2 of EdIn-GL and EdIn-NR do not differ with regard to the types of individual knowledge/concepts and the types of values/concerns voiced by participants.What is striking is that compared to part 1, the diversity of types is considerably reduced.In presenting the results of their assessment of energy policy measures, the participants voiced only environment-related values, human-related values, knowledge/concepts about societal steering of consumer behaviour, and knowledge/concepts about processes of policy-making.In the case of EdIn-GL, this reduction involves, at the same time, a partial change of types, because in part 1 of EdIn-GL, the participants had not voiced environment-related values and knowledge/concepts about societal steering of consumer behaviour.
In the overarching discussions about energy policy in part 2, the diversity of types that was manifested broadened again, much more so in EdIn-NR than in EdIn-GL (in the latter, the diversity increased by two types, while in EdIn-NR, it increased by four types).In both EdIn-GL and EdIn-NR, participants in the discussions uttered again (as in part 1) individual knowledge/concepts about consumer behaviour in society and about how to change their own consumer behaviour, but only in EdIn-NR did they voice knowledge/concepts about their own consumer behaviour.Those types that were voiced in the working groups' presentations were also voiced in these discussions, with one striking exception: The participants of EdIn-NR did not voice environment-related values.
Looking across all parts of EdIn shows, firstly, that in both EdIn-GL and EdIn-NR, participants after part 1 no longer voiced values/concerns by assessing specific human acts.Secondly, it reveals that human-related values as well as knowledge/concepts about policy-making processes were voiced from the beginning until the end in both EdIn-GL and EdIn-NR, and thirdly, that knowledge/concepts about technical solutions was voiced only in EdIn-NR.

Discussion
In Section 1, we raised the question of whether it is possible to promote citizen competence for sustainable consumption of adults by educational offerings, and how such offerings should be designed (with a view to both didactics and content).In this section, we discuss the answers to this question provided by our data.Before doing so, we engage in a short reflection about our approach to analysing the data.

Investigating Effects of Educational Activities
It is not new knowledge that the effects of educational interventions are hard to capture because, firstly, it is basically not possible to control for effects caused by the individuality of the participants and by group dynamics.Secondly, the effect of educational interventions cannot be isolated, that is, it is not possible to ascribe changes in the perspective (knowledge/concepts and values/concerns) and in the acts of people to educational interventions with certainty, because the influence of an educational intervention cannot be isolated.Furthermore, the influence of educational interventions must not necessarily be linear, and it is hard to predict when and how it will show.All of this applies even more to educational interventions that are as short and isolated (and attended on a voluntary basis) as EdIn and that have, as EdIn did, a limited (and small) number of participants.For this reason, we chose, firstly, to inquire into the immediate effects of EdIn, that is, into what happened while it took place.Secondly, we decided to use different and complementary methodical approaches in analysing the data and to focus on the comparison of the results of EdIn-GL with those of EdIn-NR.These measures cancel out, at least to some extent, the problem that other influences blur the immediate effects of EdIn, and the problem that the results depend on the individuality of the participants and the group dynamics.This procedure is rather time-consuming, but it has proven itself for investigating effects of educational activities if an interdisciplinary research team is at hand.

Does the Design We Developed for EdIn Work? What Can Be Achieved by Such an Educational Offering?
Citizen competence for sustainable consumption is the ability of individuals to assess consumption policies and to participate in societal decision-making toward sustainable consumption (see Section 1).According to the notion we adopted, this entails three elements, and in the following, before listing the limitations of our study, we discuss our results along these elements (see Section 1.2.2): 1.
Individuals must be willing and able to engage in a deliberation aiming at developing policy options and achieving consensus.

2.
Individuals must be willing and able to engage in individual, mutual, and collective processes of learning and reflection, that is, to acquire new information, to collectively integrate knowledge, to understand and compare perspectives, to question both their own perspective and that of others, and to revise their own (pre)conceptions and broaden their perspective.

3.
Individuals must be willing and able to become involved and to take on responsibility, to move beyond their individual interest and toward the common good.

Engaging in a Deliberation Aiming at Developing Policy Options and Achieving Consensus
In fulfilling the task assigned to them in EdIn, the participants were, in both EdIn-GL and EdIn-NR, able to collaboratively and consensually assess policy options by identifying policy measures they found particularly convincing (or unconvincing).However, they did not only succeed in a consensual policy-assessment, they were also able to reflect on this act by developing and naming assessment criteria.In EdIn-GL as well as in EdIn-NR, this task supported participants in leaving the breadth of the immediately precedent discussions and focusing on a smaller number of types of individual knowledge/concepts and of individual values/concerns, namely on those that seem to be particularly important when it comes to policy-making (defining values and reflecting on how to induce corresponding change).In responding to this task, the participants no longer drew on knowledge about (changing) their own consumer behaviour as they had done in the precedent discussion and as they did in the subsequent discussion.That is, the design of EdIn provided an opportunity of gaining practical experience in a deliberation aiming at collectively assessing policy options.
The task was not only to assess policy options.Rather, in these acts of policy-assessment and reflection, the working groups were asked to apply a given perspective (that is, they had to translate a given perspective into criteria).This, in turn, has been done more concisely in EdIn-GL than in EdIn-NR: The criteria used were more focused, and the specific focal perspective was more prominent; that is, this application seems to have been easier in EdIn-GL than in EdIn-NR.This is backed by the fact that in the subsequent discussion, there was a debate about applying the given perspective to energy policy only in EdIn-GL.This cannot be explained by participants being more familiar with the good life perspective, because the feedback by participants of EdIn-GL shows how new and unusual this perspective had been for them.This allows for the conclusion that the task we have developed for EdIn supported especially participants in EdIn-GL in integrating a perspective on energy policy they were not familiar with into collaborative and consensual policy assessment.

Engaging in Individual, Mutual, and Collective Processes of Learning and Reflection
In both EdIn-GL and EdIn-NR, the presentations by the moderators, the initiating questions, and the discussions induced by these presentations and questions supported participants in drawing connections to own experiences and in inferring own conclusions, and they were effective in encouraging participants to activate a broad range of types of knowledge/concepts, of values/concerns, and of experiences.That is, they were effective in comprehensively activating the participants' perspectives and in linking the chosen content to their perspectives.Participants understood the presented content, and they were able to reflect and discuss it in a meaningful way by formulating further considerations and drawing conclusions.In these acts of reflection and discussion, they referred to and drew on what the other participants said, that is, they did not simply contribute individual statements not connected to those of the others or lead a dialogue solely with the moderators but engaged in an integrative conversation.
According to the participants, EdIn provided food for thought and broadened their perception of energy policy, that is, they acquired and assimilated information new to them.This was caused not only by the content provided by the moderators but also by exchanging and comparing their own perspective with that of the other participants; in EdIn-NR, this seems to have been even more important in widening their perspectives than what was presented by the moderators.The participants' feedback shows that the methodical design of EdIn encouraged them to voice their opinions and concerns, invited them to exchange and compare perspectives, and supported them in reflecting and learning, and this did not depend on the focal content of EdIn-GL or EdIn-NR.
There are, though, differences between EdIn-GL and EdIn-NR: In EdIn-GL, participants were able to formulate more further considerations that were in line with the focal content, that is, they led a more differentiated discussion, although they found it unusual to approach energy policy from this angle (in contrast to the participants of EdIn-NR, who did not denote the approach to be unusual).Similarly, in applying the focal content to energy policy, the participants of EdIn-GL succeeded better than those of EdIn-NR in integrating this content in their assessment of policy options.This allows for the conclusion that EdIn, by its design, supported learning and reflection but that more observable learning happened in EdIn-GL than in EdIn-NR.

Becoming Involved and Taking on Responsibility, Moving Beyond the Own Individual Interest, and Moving toward the Common Good
In presenting the results of their collective assessment of policy options, all working groups in EdIn-GL and in EdIn-NR recurred to environment-related values, to human-related values, to knowledge/concepts about societal steering of consumer behaviour, and to knowledge/concepts about processes of policy-making.And all of them used only criteria that are either oriented toward the common good or target the issue of policy-making in a general sense (or other issues/impacts at the societal level).That is, none of the working groups recurred to knowledge/concepts related to the own consumer behaviour of the participants, and none of them used criteria putting the actual or potential impacts of a measure on the participants centre stage.This means that in fulfilling their policy-making task, they actually oriented themselves toward the common good and the community.The comparison, especially with the types of knowledge/concepts voiced by the participants in part 1 of EdIn, allows to conclude that the task given to the working groups supported the participants in leaving behind questions and issues dealing with their own consumer behaviour and in focusing on the common good and the political acting of the (Swiss) community.
This picture changes in the subsequent overarching discussions about energy policy.Although the participants did not drop these issues related to society, in these discussions, knowledge/concepts about their own acts as consumers gained importance again, and it did to a greater extent in EdIn-NR than in EdIn-GL.To our surprise, neither in EdIn-GL nor in EdIn-NR did participants voice knowledge about their own acts as citizens, and the question of their own responsible acting focused on their consumer acts.Additionally, while in EdIn-GL a general discussion about energy policy took place at least to some extent (dealing with the question of applying the good life perspective to energy policy), no such discussion took place in EdIn-NR, that is, in EdIn-NR the discussion mostly revolved around the measures of energy policy that had already been discussed in the working groups.
The feedback of the participants shows that at least EdIn-GL was effective insofar as participants started to think about their own acts as citizens and their own role in energy policy and started to feel responsible in their role as citizens (and not only in their role as consumers), but EdIn obviously did not provide a stimulus strong enough to turn this potential into observable manifestations.In other words: With regard to promoting this element of citizen competence, participants need stronger support by an appropriate method than was the case in EdIn.

Limitations of Our Study
The semi-experimental setting of our study, the fact that we can compare the results of two interventions in two groups of respondents, and the interdisciplinary methodological triangulation we adopted in the analysis of our data cancel out, at least to some extent, the problem that other influences blur the immediate effects of EdIn, and the problem that the results depend on the individuality of the participants and the group dynamics.
Nevertheless, our study has some limitations that limit the possibilities of assessing EdIn's suitability to promote citizen competence for sustainable consumption in adults: Firstly, we have data about the self-perceptions of the participants, but no 'neutral' ex ante and ex post comparison that can tell us how the individual participants developed from before to after having attended EdIn.Secondly, we have data about the immediate effects of EdIn and, again, about the self-perceptions of the participants (some months later), but no data about long-term effects of EdIn on the participants.Finally, we have results for the field of energy policy, but no results from fielding EdIn in another field of sustainable consumption policy.With regard to this question, our results sum up to the conclusion that the topic of energy policy should be approached by focusing on good life and justice and not by focusing on natural resources and the natural environment.
Firstly, the good life perspective connects well to the perspectives of individuals in their role as citizens, while the natural resource perspective does not connect equally well to their perspectives.In EdIn-GL, participants did not contradict what was presented to them by the moderators, while they did so in EdIn-NR.In EdIn-GL, participants neither left the given focus good life nor did they redefine it.By contrast, in EdIn-NR participants left the given focus natural resources by broadening and by redefining it, that is, participants had to redefine the focal content in order to be able to discuss it.Although the participants were, in both EdIn-GL and EdIn-NR, able to collectively assess energy policy measures, to reflect the criteria they had used, and to integrate new information in doing so, the application of the given perspective (good life in EdIn-GL and natural resources in EdIn-NR) succeeded more with the first than with the latter.Additionally, while the issue of policy-making in a general sense was discussed in both EdIn-GL and EdIn-NR, only in EdIn-GL was there a debate about applying the given perspective to energy policy.In their feedback, the participants of EdIn-GL emphasised the advantages of linking energy policy to the broader issue of quality of life, while the participants of EdIn-NR did nothing similar (this should not be overestimated, though, because it can be caused by the novelty the participants attributed to using a good life approach in discussing energy policy).With a view to the types of values/concerns participants voiced in EdIn, participants in EdIn-NR voiced human-related values right from the beginning, although such values were not addressed in the presentations and questions by the moderators, and they did not voice environment-related values during the overarching discussion about energy policy, although they used criteria related to the environment in assessing policy options.This seeming contradiction means that they used such criteria but did not ascribe corresponding values to issues/facts/ideas.
Secondly, focusing on good life and justice has, as our results show (see above), a bigger potential with a view to promoting citizen competence in each of the elements discussed above.While in EdIn-GL, the participants in part 2 of EdIn seized aspects that had been discussed in part 1 and that were related to the focus good life, the participants of EdIn-NR did not.The aspects the participants of EdIn-NR seized in part 2 that had been discussed in part 1 related to contents that were already a broadening of the focus (the only exception was grey energy, and this was caused by an intervention by the moderators).That is, it came more naturally to the participants to assimilate and apply information belonging to the focus good life and justice.The participants of EdIn-GL as well as those of EdIn-NR said that attending EdIn had provided food for thought, but while those of EdIn-GL attributed this to both the exchange with the perspectives of the other participants and the content of the discussion, those of EdIn-NR attributed this more to the exchange with the other participants than to the content of the discussion.
Promoting citizen competence should link to and proceed from the perspective characterising individuals in their role as citizens.That is, it should take up the knowledge/concepts, values/concerns, and experiences relevant to this perspective and support individuals in broadening, differentiating, reflecting, and revising these knowledge/concepts, values/concerns, and experiences.Environmental issues do not correspond equally well to this perspective as issues of good life and justice do.Trying to change this would mean to impose on individuals in their role as citizens another perspective instead of taking seriously and nurturing their specific perspective and, thus, their special expertise.Our results show that approaching energy policy from a good life perspective neither encompasses that environmental issues are neglected nor necessarily carries the risk that concerns related to the natural environment are set aside: The participants of EdIn-GL used criteria related to the environment in their policy-assessment in part 2 of EdIn, although they had not voiced environment-related values in part 1 of EdIn, and although such values had not been addressed in the presentations and questions by the moderators.

Does It Make Sense to Offer Such Educational Activities or Is It Even Necessary to Do So?
Despite the limitations of our study, the results we gained through our educational intervention show that it is possible to develop and implement effective educational offerings targeting the promotion of citizen competence for sustainable consumption in adults.The focus of our intervention was energy policy, but we are convinced that our findings apply to other policy fields in consumption as well.Thus, if this competence shall be promoted, it is not useless, but it makes sense to offer such short and isolated educational activities that are attended on a voluntary basis.
This raises the question of who does or would attend such activities.Our experiences show that things such as the duration of an activity and the necessity to travel to another place can be considerable obstacles for people to participate.Our experiences also show that such activities possibly systematically exclude specific groups of people (see Table 3).The individuals we invited to participate can be considered to be at least to some extent interested in energy policy, were willing to invest time in our project activities by volunteering for two interviews, and were personally invited to attend EdIn.Nevertheless, more women than men followed our invitation, more middle-aged than younger and older people, more individuals with a higher education, and more living in a town.Our results indicate some other points that might deter people from attending such activities: The fear of being subjected to an activity advertising a party politics, the fear of being subjected to a nonfactual, undifferentiated, and confrontational (possibly also moralising) debate, not knowing exactly what to expect, a reluctance to leave one's own comfort zone and/or to expose oneself to the unknown or not being sure of being able to live up to expectations.To be inclusive, considerable efforts must be made in reaching out to potential participants.
Our research produced one rather unexpected result that we think might be an argument not for the possibility, but for the necessity of providing such educational offerings: Although our sample consisted of individuals not being averse to talking about energy policy, the feedback by the participants of EdIn revealed that in their role of 'normal' citizens, they did not necessarily perceive themselves to be part of energy policy decision-making, they were not sure about being able to contribute to energy policy, and they did not really feel invited to become involved in energy policy processes.This is, especially in a Swiss context, rather irritating, because people are called to vote several times per year and because they are used to quite a number of political instruments.That is, despite them knowing much about the legal and political system and functioning of society, they did not feel part of political decision-making and were not sure what they could contribute.There is, in other words, a deficiency with regard to individuals knowing about their actual or potential role as citizens in energy policy.This explains, for one thing, why in EdIn, participants did not discuss their own acts as citizens (but only their own acts as consumers).For another thing, this points to the necessity of providing opportunities for people in which they can reflect upon their role as citizens and recognise what they can contribute to societal decision-making in the field of sustainable consumption.Otherwise, people will not develop the feeling that they are invited to become involved and they will not recognise they are a part of decision-making and can participate in decision-making processes.And our research shows that such activities would be appreciated.

Conclusions
In this section, we draw some conclusions with a view to adult civic education for sustainable consumption, that is, to educational offerings aimed at promoting citizen competence for sustainable consumption in adults.
The first conclusion refers to the didactical design of the educational intervention, EdIn, we developed and tested.EdIn was both an intervention serving the purpose of providing data to answer research questions and an activity of civic education designed with the aim of being implementable by third parties (thus allowing to investigate a 'natural' educational setting and not an artificial one).Our results show that the didactical design of EdIn was successful in supporting learning processes related to citizen competence although EdIn was isolated and short.EdIn also met the criteria that activities of civic education for sustainable consumption should meet (see Section 1).This sums up to the conclusion that in terms of its didactical design, EdIn can be implemented outside the project's context.Because EdIn can easily be adapted to other policy fields of sustainable consumption, it can also be implemented beyond the scope of energy policy.With a view to its implementation, revisions should, however, be considered to the overarching discussion in part 2 of EdIn in order to increase the potential of stimulating a reflection about the participants' acting as citizens and their role in energy policy (or in other sustainable consumption policies).This should be considered not only with a view to encouraging participants to get involved in sustainability politics, but also with a view to helping them to overcome the impression that sustainable consumption policy is a "restricted area" for citizens (see, e.g., Reference [55] for the necessity to overcome this impression).
The second conclusion refers to the content of EdIn and, on a more general level, to the question of whether in adult civic education for sustainable consumption the topic of sustainable consumption policies should be approached by adopting a good life perspective or a natural resource perspective.Our results show that the former links better to the perspective of individuals in their role as citizens and allows to a greater extent to broaden, differentiate, reflect, and revise their perspective (knowledge/concepts, values/concerns, experiences).Choosing quality of life and justice as the core content of civic education for sustainable consumption is, thus, more suitable to support the development of citizen competence.Negating this and insisting instead that the goal of adult civic education should be to improve the environmental literacy of citizens (or similar) and thus to build an informed citizenry with regard to environmental issues equals to proceeding from what experts define to be the relevant knowledge and not taking seriously and nurturing the special perspective and expertise of citizens.This, in turn, sums up to not taking citizens seriously as a distinct actor in societal decision-making with regard to sustainable consumption policies.By contrast, activities of civic education that take the perspective of citizens seriously might contribute to people feeling invited to societal decision-making and perceiving themselves as a part of politics for sustainable consumption.This, in turn, could contribute to establishing deliberative politics (according to Carcasson and Sparin [32], a necessary complement to adversarial politics and expert politics often neglected not only in policy-making, but also in civic education) and, thus, to a more consensual sustainable consumption policy.
This last point leads to our third conclusion referring to the necessity of providing adult civic education for sustainable consumption focusing on deliberation and interaction.McGregor writes that "learning and citizenship are lifelong activities" [16] (p.4).Accordingly, opportunities to enhance citizen competence for sustainable consumption should not be reserved to formal education but should
