Promoting Sustainability Transparency in European Local Governments: An Empirical Analysis Based on Administrative Cultures

: Nowadays, the transparency of governments with respect to the sustainability of public services is a very interesting issue for stakeholders and academics. It has led to previous research and international organisations (EU, IMF, OECD, United Nations, IFAC, G-20, World Bank) to recommend promotion of the online dissemination of economic, social and environmental information. Based on previous studies about e-government and the inﬂuence of administrative cultures on governmental accountability, this paper seeks to identify political actions useful to improve the practices of transparency on economic, social and environmental sustainability in European local governments. We perform a comparative analysis of sustainability information published on the websites of 72 local governments in 10 European countries grouped into main three cultural contexts (Anglo-Saxon, Southern European and Nordic). Using international sustainability reporting guidelines, our results reveal signiﬁcant differences in local government transparency in each context. The most transparent local governments are the Anglo-Saxon ones, followed by Southern European and Nordic governments. Based on individualized empirical results for each administrative style, our conclusions propose useful policy interventions to enhance sustainability transparency within each cultural tradition, such as development of legal rules on transparency and sustainability, tools to motivate local managers for online diffusion of sustainability information and analysis of information needs of


Introduction
During the last years, various authors [1][2][3] have concluded that on a global level, the effect of the economic crisis on government finances has transformed public-policy sustainability into a topic of substantial concern for citizens, politicians, managers and other stakeholders.In fact, against the backdrop of worldwide government financial crises, several international bodies [4][5][6][7][8] have emphasised the need to adopt good governance practices for public policies of sustainability and encourage transparency regarding social, economic and environmental information [9,10].
In this line, numerous studies have emphasised that transparency of public policies is a key element of good governance [2,3,9,11,12].Simultaneously, various international bodies [5,7] recommend public-sector entities to adopt information dissemination practices that respond to increasing stakeholder demands.In recognition of the importance of transparency and accountability, numerous countries have adopted laws to strengthen communication between government and citizens with the goal of guaranteeing public access to government information [13][14][15].
More specifically, prior research has concluded that the study of transparency practices with respect to sustainability of public policies is particularly important for local governments due to their direct contact with citizens, the volume of resources that the governments manage and the tenuous government financial circumstances [10,16,17].Similarly, studies [3,14,18] have recognised the timeliness and relevance of studying e-government contributions to online transparency of sustainability for local governments.
However, despite the interest in studying online transparency regarding sustainability of public services, few studies have focused on the online dissemination of this type of information [12,19,20].Previous studies have proposed the usefulness of comparing sustainability transparency practices across different contexts given that the administrative cultures of different countries influence the level of government openness toward citizens and their accountability practices [21].
Thus, to advance the study of the sustainability transparency practices of local governments, it would be useful to examine what several authors refer to as the three main cultural traditions in public administration in Western democracies: Anglo-Saxon, Southern European and Nordic or Scandinavian [22][23][24].
Based on this motivation, the present paper seeks to identify political actions useful to improve the practices of transparency for economic, social and environmental sustainability in European local governments, studying the three predominant public administration styles.We perform a comparative analysis of online transparency regarding sustainability in these three cultural contexts by studying the websites of 72 local governments which are grouped according to whether they belong to Anglo-Saxon, Southern European or Nordic countries.This approach enables us to understand the contributions of each type of administrative culture to government sustainability transparency through the study of the conditioning factors of the three predominant administrative styles.Our empirical results support the identification of some useful policy interventions to enhance sustainability transparency within each cultural tradition, such as development of legal rules on transparency and sustainability, tools to motivate local managers for online diffusion of sustainability information and analysis of information needs of stakeholders.

Administrative Culture and Its Effect on Government Transparency
According to the European Union [6], transparency should be understood as the right of citizens to access government information.Under this same approach, IFAC [5] has defined transparency in terms of information disclosed regarding not only the actions taken, but also the comprehension of these actions by stakeholders and the responses made by them.
As stated in this definition of transparency and using the New Public Management approach during recent decades, a significant number of countries has implemented administrative reforms with the goal of promoting transparency as a tool for accountability, with advocacy particularly directed at local governments [25][26][27].More recently, using a more modern approach (Public Value Governance) in which citizens are viewed as participants in solving government problems, transparency has played an even more significant role insofar as citizens must be well informed to strengthen their active involvement in decisions regarding public matters and to make decisions in support of their government leaders [11,28].
In each country, administrative reforms have been developed differently.As previous researchers have observed [22,29], styles of administrative culture have influenced the role of the State and the focus of transparency and accountability (by way of different legal frameworks and organisational structures) such that countries with the same cultural traditions have implemented reforms in similar ways [30,31].
Accordingly, several authors have discerned three main administrative cultures in Europe (i.e., Anglo-Saxon, Southern European and Nordic) in which concepts of transparency and accountability, the way in which these concepts are applied, and government commitment play essential roles [25,26].In fact, certain authors have concluded that administrative traditions significantly affect the dissemination of government information [32,33].Although these administrative styles can be disaggregated by adding other types such as the Germanic countries, in this paper, we have taken the three administrative traditions that are considered to be principal or predominant in international organizations and previous works [23,[34][35][36].However, authors Pina, Torres and Royo [37] and Hammerschmid and Meyer [38] consider the Germanic countries within continental countries taking into account their similarities in administrative structures.
In this sense, following Navarro and Rodríguez [22], Howlett [39] or Kickert [23], the administrative cultures that differ the most one from the other are the Anglo-Saxon countries and the Southern European countries, whose governments employ different styles of public management.Whereas Anglo-Saxon culture uses a model based on participation, Southern European culture uses a reactive, enforcement-based model, which can affect the transparency practices of public entities in significant ways.
Additionally, differences among transparency practices can originate from each country's normative context.In fact, the implementation of laws regarding citizen access to government information has occurred at very different times in different countries.For example, the United Kingdom's freedom of information law was passed in 2000, Italy's in 1990, Norway's in 1970 and Finland's in 1951 [13].
In Anglo-Saxon countries, governments opt for a competence focus conceiving the citizen as a "client" and emphasising transparency, which can generate increased trust in government [40].In contrast, Southern European governments pay less attention to transparency and accountability and their public administrations are organised according to bureaucratic legal norms [41].
According to CSR Europe [42], in Nordic cultures, special efforts are exerted to promote corporate social responsibility, in which transparency is a fundamental concept, and to incorporate diverse aspects of transparency into their regulations.These countries have been influenced by the Southern European and Anglo-Saxon public administration traditions and therefore can be considered to be hybrids of these two types of public administration [23,43].Compared with Anglo-Saxon countries, Nordic countries have a substantially more pragmatic vision of reforms.They develop regulatory changes to promote quality services and envision an active role for stakeholders in the management and evaluation of public policies.According to the model defended by Bryson et al. [28] and Greco et al. [11], this approach should be combined with enhanced government transparency.
In investigations of the different implications of government transparency, a number of authors [16,44,45] have analysed the dissemination of financial information by local governments in specific countries that belong to the same administrative culture.However, despite recommendations from international bodies, none of these studies have analysed the disclosure of information regarding the sustainability or performed a comparative analysis of different cultural contexts.Thus, our research objective is timely and valuable.

Sample Selection
As previously indicated, a country's type of administrative culture can influence a government's level of openness, the relations of public entities with the stakeholders and the emphasis placed on transparency.Building on that basis, our empirical study performs a comparative analysis of the sustainability-related content disseminated on websites of a group of local governments.These local governments are divided into three groups that represent the three European cultural contexts: Anglo-Saxon, Southern European and Nordic.We chose these three types of administrative culture because reforms have followed certain patterns in countries that have common administrative traditions and share certain cultural values and because this feature has contributed to improving government transparency [41].These three administrative styles can be disaggregated by adding other types such as the Germanic countries.However, in our sample, we have taken only the three administrative traditions that are considered main or predominant by international organizations and previous works [23,[34][35][36].
Our study sample includes 10 countries as follows: Anglo-Saxon countries (the United Kingdom and Ireland), Southern European countries (Italy, Portugal and Spain) and Nordic countries (Norway, Finland, Denmark, Sweden and the Netherlands).
Using contributions from a wide panel of international experts, the Centre for Law and Democracy [13] has developed the Global Right to Information Rating.In this ranking system, experts analyse national access-to-information laws in 102 countries and score the quality of each legal framework using 61 indicators divided into seven sections (i.e., right of access, scope, procedure requests, exceptions and refusals, appeals, sanctions and protections and promotional measures).The maximum cumulative core is 150.As shown in Table 1, Nordic countries were generally the first to adopt government transparency laws.These countries are followed by two continental countries (Portugal and Italy) and one Anglo-Saxon country (UK) as well as more recently by Ireland and Spain.However, the scores for the quality of transparency-related legal frameworks do not follow this order.Instead, Anglo-Saxon countries occupy the highest positions, on the whole, and Southern European countries occupy the lowest, with Nordic countries in intermediate positions.Nevertheless, the first position is occupied by a Nordic country (Finland).Therefore, the exception is Finland, which achieved the highest score of all 10 countries in the sample.Source: [13].
We chose local governments for several reasons.First, international organisations consider local government to be a highly suitable level of government for the study of sustainability transparency [46].Likewise, in its Fiscal Sustainability Report, the EU [7] indicated that in light of the worrisome situation for public finances, it is necessary to continue examining sustainability issues in local governments.Finally, findings from prior studies indicate that local governments are a highly suitable type of government for the study of sustainability practices because their direct contact with citizens makes it easier for them to become acquainted with different stakeholder demands [12,47].
Our sample consists of 72 local governments of the 10 countries mentioned above.Local governments with large populations have been selected, except in some cases in which they have been chosen because of their economic impact and the resources they manage, seeking the representativeness of the sample.These local governments are distributed among the administrative cultures as follows: 25 Anglo-Saxon governments, 26 Southern European governments and 21 Nordic governments.As in prior studies on local government transparency [16,20,33], we have chosen municipalities with large populations for the following reasons: (a) EU [7] recommends studying sustainability in larger municipalities, which are particularly subject to the negative effects of an aging population and to high levels of debt and deficit; (b) larger municipalities provide a wider range of services; however, at the same time, the provided services tend to be more homogenous; (c) these municipalities have greater access to new technologies and make greater use of them; (d) the administrative staff typically has a greater degree of specialisation and professionalism than that of smaller municipalities; (e) these municipalities have a larger number and variety of stakeholders; (f) the larger volume of managed resources, which suggests that more investments should be dedicated to ensuring sustainability.

Methodology
At a global level, e-government practices play a crucial role in increasing government transparency by facilitating free and universal access to information via the Web [14,48].
Today, higher levels of transparency may be associated with increased confidence in an organisation's commitment to sustainability and, in many cases, this confidence is acquired by increasing the level of disclosure [49].The Web enables public officials to provide a larger quantity of information and to do it in a more frequently and accessible way, thus removing barriers between citizens and government [18].More specifically, Estevez and Janowski [50] note that the Internet and the Web are key elements in the link between e-government and sustainable development.Likewise, Janowski [51] identifies that stages of Digital Government Evolution Model can be characterized by variables like the internal transformation or the relationships between government and various non-government stakeholders, and that the context can influence in the transformation.
Thus, and in line with previous studies on government information [19,20,47], in our empirical study we measure transparency according to the volume of online information published on the websites of the 72 local governments of our sample, including all departments.
To measure the volume of sustainability information available on each website, we use standard guidelines and recommendations issued by international bodies.The OECD [48], the World Bank [8] and the UN Global Compact [52] have published useful frameworks.However, the G3 version of the GRI guidelines [53] was long considered to be the fundamental standard for the dissemination of sustainability information [54].
Particularly in the public sphere, Bernhart [55] and Beare et al. [2], among others, assert that these guidelines currently have the largest impact on public-sector entities and the number of public organisations that implement these recommendations has dramatically increased.
Therefore, in our empirical study, we use the sustainability report model recommended by the GRI, specifically the items proposed in the G3 and G4 guidelines, as well as those included in specific supplements published for public entities [53,56,57], thus obtaining a set of indicators to measure economic, social and environmental aspects.Our questionnaire consists of 75 items structured into four blocks: general information (28 items), economic information (24 items), social information (10 items) and environmental information (13 items), of which the content and results are shown in Appendix A.
We employed a measurement system based on website content analysis to study whether the websites of the 72 local governments disseminate the items included in the questionnaire.We assign a value of 1 to each item if the information is published on a given local government website and a value of 0 if the information is not published.The method for data collection consisted of: first, two researchers sought the information within websites separately; second, the information indicated was pooled; in case of divergence, a value of 1 was selected, since it meant one of the two researchers had found the variable on the web.This process of data collection has been validated in previous research [58].
By this we obtain a numerical indicator for each website via the sum of the scores obtained for the different items.This sum is the value of our sustainability transparency indicator for the local governments being studied.Additionally, to guarantee the representativeness of the comparative results, we calculate the average frequencies using the sum of items within each block, not the sum of items from the entire questionnaire.
This method enables us to perform a descriptive study based on the analysis of frequencies to determine the level of sustainability information disclosure in general terms, by administrative culture, by cities, by block or type of information and for each of the defined variables or items.Additionally, we have developed a ranking of countries according to their indices of sustainability information dissemination.For this purpose, we treat each block as 25%, based upon Dutta and Lawson's [59] conclusions.We have assigned the same weight (25%) to each block because previous research [32,59,60] concluded that when the number of items is different in each block of the questionnaire, it is necessary to guarantee homogeneity by means of the balance in each block so that the comparative analysis between countries belonging to different administrative styles is relevant.
Once the frequencies of all of the sustainability transparency indicators were obtained, we performed a comparative analysis of the local governments that represent each of the three administrative cultures.To this end, we use variance analysis, which is considered a useful statistical test to determine whether significant differences exist between the values obtained by different groups, as observed by Zar [61].In fact, variance analysis has been frequently used in previous studies [62].We also perform multiple contrasts or post-hoc comparisons in order to identify the values that differ most among groups.With this goal in mind and following authors who specialise in statistical analysis when there was homogeneity of variance, we used Tukey's honest test (HSD) and when the variance was not homogeneous, we used the Games Howell test [61,63].

Empirical Results
Individually applying content analysis to the websites of the 72 local governments in our sample, we obtained the data included in Table 2, which presents the indices of sustainability transparency for the three analysed groups of local governments (i.e., Anglo-Saxon, Nordic and Southern European) differentiated by blocks: general, economic, social and environmental.The individual frequencies for each of the 75 items in detail, differentiating by administrative culture are shown in Appendix A. As can be noted from the aggregated data of the three administrative cultures, the analysed local governments achieve great transparency on average, for general information on sustainability (62.5%), followed by social information (59.4%) and economic information (58.2%), with environmental transparency occupying the last position (52.12%).Additionally, as the standard deviations included in Table 2 illustrate, the level of uniformity among results differs between blocks.Economic information had the greatest dispersion of results (19.74), whereas general information was the most uniform (10.46).Social and environmental information was similarly situated in between (15.75 and 15.08).
These results indicate a common pattern of behaviour given that the websites of the 72 analysed local governments, as instruments of e-government, are being used as tools of sustainability information dissemination.
However, the differences between levels of transparency are not similar across comparisons (Table 3).If we compare transparency indices in pairs (i.e., two by two), the Anglo-Saxon-Southern European and Southern European-Nordic distances between transparency indices are very similar for general information (10.2% and 10.1%) and social information (15.9% and 15.4%).In contrast, these distances are significantly greater in the case of economic sustainability (12.5% for Anglo-Saxon-Southern European variance and 26.8% for Southern European-Nordic variance) and in the case of environmental sustainability (24% and −14.1%, respectively).These results appear to corroborate the conclusions of studies, such as those by Kickert [23] or Lozano et al. [43], that characterise the Nordic style of government as a mixed style (with Anglo-Saxon and Southern European cultural influences).Our results also represent advances of previous findings.From our results, it seems that positive Anglo-Saxon cultural influence on Nordic governments has been substantially stronger with respect to the dissemination of environmental information.However, the negative effect of Southern European culture has been stronger regarding the disclosure of economic information.Nevertheless, we have not obtained empirical evidence to contradict the findings of Navarro and Rodríguez [22] or Kickert [23], who concluded that the greatest differences between administrative cultures are between Anglo-Saxon and Southern European countries.
In any case, these differences between administrative cultures are consistent with the different transparency indices that are presented in the different blocks for each culture (Table 2).In Anglo-Saxon governments, social information (73.2%) and economic information (72.3%) are disseminated at the highest rates, followed by general information (70.1%) and, at a greater distance, environmental information (54.2%).However, in the Southern European governments, although environmental information is also disseminated (44.3%), the highest level of dissemination occurs with general information (59.9%), followed closely by economic information (59.8%) and social information (57.3%).
This uneven behaviour regarding sustainability transparency can also be observed among the Nordic governments in which the highest level of dissemination occurs with general information (49.8%), followed by environmental information (44.3%), social information (41.9%) and, at a much greater distance, economic information (33%).
Following the Fukuyama essays [64], it is interesting to analyse the relationship between the level of administrative corruption in the countries and the sustainability transparency index, as Table 4 shows for EU countries.The comparison of our empirical results with the Transparency International "Transparency Perception Index" (2016) shows that the level of administrative corruption does not seem to be significantly influencing the governments' behaviour related to the diffusion of sustainability information.In average values, according to the Corruption Perception Index, the Nordic countries have the lowest levels of corruption (86.6 points on a maximum of 90 and position 2.8 of 28).In contrast, the Nordic countries have the lowest sustainability transparency index.However, Southern European countries have higher rates of perceived corruption than the Nordic countries (55.6 points and position 18.6) but their transparency index is higher than this index in Nordic countries.Similarly, the Anglo-Saxon countries have the highest sustainability transparency index and yet their level of administrative corruption is somewhat higher than the level of the Nordic countries (77 points and position 7.5).In parallel, this comparative analysis also reveals our results do not allow to support the influence of the level of sustainability transparency on the level of administrative corruption.If we examine the country rankings included in Table 5, the added indices reveal that the local governments with the greatest sustainability transparency are Anglo-Saxon (Ireland, 0.69; the United Kingdom, 0.67), whereas those with least transparency are the local Nordic governments (Netherlands, 0.26; Sweden, 0.39; Denmark, 0.44).Norway is an exception.Its local governments produce an aggregate index of 0.60, greater than Italy (0.60) and Spain (0.51), which are Southern European countries.
To properly interpret our empirical results, it is necessary to take into account that the country indexes are based on the analysis of local governments, not including other levels of government, as shown in the tables above.
The results of the levels of dissemination of information on sustainability of cities show that in block I on general information, the indexes are intermediate levels, except for the city of Palermo (92.9%), which stands out for its commitment in this dimension.Block II of economic information highlights the English city of Stevenage, and the Italians Milano and Padova all with an index of 91.7%.On the contrary, the Nordic cities of Espoo (12.5%),Le Hague (4.2%) and Utrecht (12.5%) have very low rates.The city of Eindhoven does not provide any of the information analysed in this dimension (0%).Some local governments in the UK and Ireland are highlighted for their transparency in block III on social issues, with very high rates (90% in Belfast, Bradford, Edinburgh, Exeter, Plymouth and Worcester) against cities like Malmoe (10%) or Catonia (10%).
Finally, in block IV of environmental information, the most extreme situations are presented.In addition to cities that comply with 100% of the items analysed (Dublin, Trondheim and Firenze) or which present very high values such as Wirral (92.3%), others appear with a low level of transparency such as Uppsala (7.7% ) and Spanish cities of Granada (7.7%), Seville (7.7%) and Valencia (7.7%).Some cities do not provide this type of information, such as the cities of Utrecht, Eindhoven and Naples (0%).Likewise, to proceed to the analysis of variance, we used the scores achieved by the local governments of each country, belonging to each of the three cultures, for each of the four analysed blocks to obtain the results shown in Table 6.As can be observed, the results of variance analysis support the position that the hypothesis of the equality of mean values should be rejected because the values that correspond to three of the four types of studied information (i.e., general, economic and social) reveal statistically significant differences between the local governments that represent the three analysed cultural contexts (i.e., Anglo-Saxon, Southern European and Nordic).However, the results of the variance analysis for environmental information dissemination indicate that the hypothesis of the equality of means should be accepted because the differences are not statistically significant.In addition, as reflected in Table 7, we have extended this analysis to identify the values that differ most among themselves.We perform multiple contrasts or post-hoc comparisons.Previously, we tested for homogeneity of variance; the test results indicate that variance is homogeneous in the indices of general information, social and environmental transparency.In contrast, in the case of economic information, the results indicate that the variance is not homogeneous.As we can observe, in line with the first results for general, social and economic information, this new statistical analysis also reveals statistically significant differences between governments that belong to the three analysed cultural contexts.However, we have not obtained significant evidence of these differences in the case of environmental sustainability.
Finally, we examined the most significant differences using individual values for each item (Appendix A).In Anglo-Saxon governments, the information that achieves the lowest level of dissemination is originated in countries in which activities in connection with and information regarding internal promotion policies are developed.In contrast, in Southern European governments, the lowest publication levels correspond to pension commitments to employees.In Nordic governments, the least disseminated topics involve average payment periods and criteria for the identification of stakeholders.It is noteworthy that the percentage spent on local suppliers divided by total expenditures is not published in any of the three analysed contexts.
Regarding the distances between Anglo-Saxon and Southern European cases, the greatest differences stem from employee pension obligations and the priorities assigned to the aspects addressed in the information supplied.In contrast, the Anglo-Saxon-Nordic principal differences are not related to these topics.Rather, they focus on financial risks, the mean payment period, future calls for tenders and capital expenditures according to financial classifications.However, Southern European-Nordic differences are centred current calls for tenders for the supply and grants offers for non-profit organisations.

Discussion
Our initial findings build on the conclusions of previous studies [44,45,47], which empirically confirmed the role of local government websites in the dissemination of financial information but did not study their specific role as instruments for publishing sustainability information.However, our results also indicate a need for significant improvements because the transparency indices do not reach 100%, which would be desirable according to the questionnaire used.In sum, information is most deficient in the area of environmental sustainability, according to poor results found out by Hawrysz Foltys [66] and Genus [67], whereas the general information that is published most closely aligns with the items recommended by international bodies.
Likewise, if we contrast the index for each country (Table 5) with data from the Global Right to Information Rating [13], our results are in line with validity and scores for Anglo-Saxon government legal frameworks, which score highest (Table 1).However, Nordic governments do not achieve transparency sustainability indices commensurate with their positions in this ranking system.Because their transparency laws were adopted earlier and their legal frameworks are of a higher quality, they should be ranked ahead of the Southern European governments.These comparisons within our empirical results suggest that the number of years that transparency laws have been in effect influences sustainability transparency to a substantially lesser degree than the suitable development of concrete legal guidelines regarding access to government information.
Similarly, a comparison of the country ranking derived from our results (Table 5) with the ranking of transparency legal framework development levels (using relative scores with a maximum of 150 (Table 1) reveals different situations depending on cultural context.In Anglo-Saxon and Southern European countries, the development of legal frameworks is more advanced than the level of sustainability transparency.However, differences are more pronounced in most Nordic countries than in Anglo-Saxon and Southern European countries.These differences between administrative cultures indicate that a government's commitment and manner of implementing transparency are decisive elements for sustainability transparency, which suggests that the conclusions of previous studies should be developed [25,32].
On the other hand, the results of comparing transparency index in pairs (i.e., two by two) (Table 3) appear to corroborate the conclusions of studies, such as those by Kickert [23] or Lozano et al. [43], that characterise the Nordic style of government as a mixed style (with Anglo-Saxon and Southern European cultural influences).Our results also represent advances of previous findings.From our results, it seems that positive Anglo-Saxon cultural influence on Nordic governments has been substantially stronger with respect to the dissemination of environmental information.However, the negative effect of Southern European culture has been stronger regarding the disclosure of economic information.Nevertheless, we have not obtained empirical evidence to contradict the findings of Navarro and Rodríguez [22] or Kickert [23], who concluded that the greatest differences between administrative cultures are between Anglo-Saxon and Southern European countries.
Finally, our results require further examination of prior findings [29][30][31], which drew conclusions regarding the influence of administrative cultures on the level of government openness toward citizens and on the commitment of local government leaders to transparency of information.In addition to the specific effect of cultural context on sustainability transparency practices, our findings support that this effect depends on the type of sustainability information because, as one can observe in each cultural context, the commitment of local government leaders to the disclosure of each type of information (i.e., general, economic, social, environmental) is not equal for the four analysed blocks.

Conclusions
Currently, sustainability of public policies and online government transparency have drawn substantial interest from stakeholders (e.g., citizens, politicians, managers and academics).In fact, diverse international bodies (the United Nations, the OECD, the G-20, the EU, IFAC, the World Bank) recommend that governments adopt good governance practices that favour public policies of sustainability by urging transparency with respect to economic, social and environmental information.
Although prior studies have analysed the dissemination of financial information on local government websites in specific countries, comparative analysis of sustainability transparency has not received the necessary attention.However, various prior studies and declarations from international bodies have recognised the timeliness and value of analysing practices regarding the dissemination of sustainability information via the comparative study of different cultural contexts because of the impact of tradition and administrative reforms in each country on the commitment of government leaders to communication with citizens and to providing access to public information.
This paper analyses the sustainability information published on the websites of 72 local governments, which were separated into three groups to represent the three European cultural contexts (i.e., Anglo-Saxon, Southern European and Nordic).A total of 10 countries were studied.Following the generally accepted international guidelines and through an analysis of website content, our empirical results reveal that the sustainability transparency of the group of analysed local governments reaches an intermediate level: 58.05% convergence with international guidelines.
As previous studies indicated, this level illustrates that websites serve as drivers of sustainability transparency and suggests the need to adopt measures to strengthen the dissemination of sustainability information among local governments in Europe.
However, our empirical analysis indicates that deficiencies in sustainability information are not similar across the three administrative cultures.This outcome suggests that the best instruments to encourage sustainability transparency could be different in the three analysed contexts.
No local government provides all the information needed to respond to the four dimensions of sustainability.Our results indicate that the most transparent local governments are the Anglo-Saxon, followed by the Southern European and, in third position, the Nordic.These results are consistent with those of prior studies that established the influence of administrative traditions on government openness to citizens and commitment to transparency.However, our findings extend the conclusions of previous studies because in addition to contrasting the specific influence of cultural context on sustainability transparency, we empirically demonstrate that the effect of this influence depends on the type of information: general, economic, social and environmental.In fact, the differences materialise in the types of sustainability information because priorities of local governments depend on cultural context.Anglo-Saxon and Nordic local governments have a greater need to improve environmental information, whereas the primary deficiency among Nordic local governments concerns economic information.
Extending the analysis of cultural contexts, the comparison of our empirical results with the Global Right to Information Rating [13], which studies transparency laws in 102 countries, enables us to obtain new findings.First, one might think that the number of years that transparency laws have been in effect (i.e., the year such a law was passed) could encourage the dissemination of government information because government leaders have dedicated more time to putting such laws into effect.However, our analysis provides empirical evidence that the amount of time that transparency laws have been in effect does not independently determine sustainability transparency.
In fact, although the oldest transparency laws in effect are those of Nordic countries and the most recent laws are those of Anglo-Saxon governments, our results reveal that Anglo-Saxon local governments have higher levels of sustainability transparency than Nordic local governments.In addition, Southern European local government sustainability transparency is also greater than that of Nordic countries, although their transparency laws are substantially more recent.
Second, if we compare our transparency indices with the values provided by the Global Right to Information Rating [13] regarding the quality of transparency laws in different countries, we can verify that the legal advance provided by each law can influences sustainability transparency.Anglo-Saxon governments appear to value the quality of their transparency laws more highly than Southern European governments, which appears to have encouraged greater sustainability transparency.However, certain Nordic countries exhibit higher levels than Anglo-Saxon governments, although Nordic governments exhibit a lower level of sustainability transparency for all types of information except environmental information.
All of these findings induce us to think that political decisions to improve sustainability transparency should be different in each of the three analysed cultural contexts, corroborating conclusions highlights by Genus [67].In the Southern European governments, which present the lowest-quality legal framework regarding access to government information, we can deduce a need to develop guidelines regarding government transparency, primarily in matters such as scope, procedure requests, exceptions and refusals as well as appeals.To this end, politicians responsible for transparency law reforms could regard regulations from Ireland, the United Kingdom or Finland as models when adopting measures to incentivise citizen participation in public affairs.
However, in the case of Anglo-Saxon countries, which have a higher-quality legal framework, it would be worthwhile to motivate local governments regarding the advantages of using existing legal tools to strengthen sustainability transparency, with a particular emphasis on its use to improve citizen trust in government, as the literature has demonstrated.Progress in the study of the criteria for stakeholder selection would be particularly useful, as well as detailed analyses of information requests for each block of sustainability, with special attention devoted to environmental sustainability.
Finally, the case of Nordic governments is distinct.The legal frameworks of such governments regarding transparency are of a higher quality than those of Southern European countries.However, their laws are old, which suggests the need to undertake regulatory reforms that better fit the current demand of stakeholders of information.In this process, the Anglo-Saxon legal model could serve as a better reference than the Southern European model.Likewise, Finland's legal framework, which is of the highest quality of the 10 studied countries, could also be a useful reference, despite its seniority.
In the Table 8 are summarized the principal suggestions to administrative cultures.
