Exploring Social Sustainability Handprint—Part 2: Sustainable Development and Sustainability

: Social sustainability is a major part of both sustainable development and sustainability including societal sustainability and overall promotion of more sustainable societies taking into account multiple social/society–environment relationships and interfaces. These contexts have a strong focus on both present and future generations, encompassing sustainable development of both people and the planet. Social sustainability handprints provide many opportunities to promote social sustainability management and assessment by organizations and people and to create changes and encourage actions that contribute to overall social and societal sustainability. This study applied qualitative approaches to explore social sustainability handprints from the perspectives of sustainable development, sustainability, social and societal sustainability and sustainability assessment and indicators. This study addressed a clear research gap and aimed at identifying key deﬁnitions, elements, approaches and development focus areas within these frameworks as well as at suggesting associated implications for social sustainability handprint development. The ﬁndings suggest that social sustainability handprints can be created through multiple actions, changes, innovations and impacts to promote social sustainability based on sustainable development, sustainability and social and societal sustainability. Various actors such as all types of organizations, individuals, groups and companies can implement these ways to create social sustainability handprints. In addition, there are multiple assessment approaches that can be applied to the assessment of social sustainability handprints such as sustainability management, assessment and indicators, encompassing multiple speciﬁc elements and approaches. essential for the well-being of both humans and and (3) wide-ranging social and environmental issues (inter-reliant dimensions) into assessment, development of indicators and collection of information


Introduction
This study explores social sustainability handprint development in the way that it supports further development and application by all types of organizations or by people/individuals, e.g., to promote, manage, assess and create changes towards social and societal sustainability. The overall handprint concept and approach were presented by the Centre for Environment Education (CEE) in 2007 at UNESCO's 4th International Conference on Environmental Education and they were linked to themes such as the principles of sustainability, human rights, social justice and gender equality and the contribution of work and lifestyles to the well-being of all life [1]. The handprint is about (1) action towards sustainability including positive and tangible actions (local/global) towards future sustainability, (2) commitment to act for the common good, (3) care for the planet and all life forms and (4) collaboration to take action for safer and healthier communities [2]. In addition, handprints are about creating and moving towards sustainability, encompassing, for example, practical actions such as education for sustainable development, choosing durable and reusable products, use of renewable energy, planting more trees or investing in sustainability [3].
Handprints can promote sustainability through a focus on positive actions of organizations, individuals and corporations and be a measure for positive action, collaboration and networking to promote sustainability [4]. For example, the handprint concept could support addressing sustainability challenges and contribute to global sustainable development targets (e.g., Agenda 2030) [5]. Previous studies have acknowledged that handprints can (1) promote a systemic thinking approach to sustainability (in addition to a linear thinking perspective on sustainability management and assessment) and innovation in an interconnected world [6], (2) be used as a tool for measuring positive impact of actions to promote sustainable development and that they are about actions to improve the well-being of people or the sustainability or healing of the planet [4] and (3) support addressing global challenges and promote innovation and collaboration among multiple actors to create positive impacts to promote sustainable development [7].
Handprints can also (1) be promising tools to promote sustainability improvements including normative approaches (what should be done and not only what has been done) [8], (2) be used as a measure of action by individuals to support measurable change of behavior to promote sustainable development [9], (3) be regarded as positive ways to think about sustainability and to take appropriate action including handprint thinking (the good we do with unlimited potential) [10,11], (4) encourage people to work for sustainable development [12] and structural changes to promote sustainable behavior by all people [13] and (5) contribute to the achievement of climate targets and advance the implementation of multiple practical measures to combat global warming [3].
Sustainable development (sustainable development refers to development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs [14]) is a broad concept and a global development goal, encompassing multiple dimensions, elements and approaches. Sustainability science and research are closely connected to this overall framework in addition to the similarly broad and diverse framework of sustainability. Sustainable development, e.g., (1) needs to promote global trends that contribute to the sustainability transition [15], (2) should be considered as a decision-making strategy by all stakeholders (from local to global level) and the main decision-making challenges can be addressed through sustainability assessment and indicators [16] and (3) requires a new vision of empowered stewardship [17]. The transition towards a more sustainable relationship between the human species and its natural life support system is a major challenge for humanity [18].
Sustainability will increasingly challenge almost all aspects of socio-economic systems and it will require new knowledge and ways to both generate and evaluate it [19]. In addition, sustainability and global sustainability transformation require governance to implement sustainability in practice [20]. The achievement of a sustainable future requires taking care of all dimensions of sustainability and addressing all interlinked impacts on people and the environment [21] as well as a fundamental shift in the development paradigm including focus on enhanced human well-being and environmental resilience [22]. It has been noted that the social dimension plays a major role in sustainability assessment [23].
There are many future collective handprints that can be created based on joint efforts [3]. Previous studies have recognized that handprint approaches could be extended to the development of a sustainability handprint [5] and that they could contribute to the creation of a circular economy including focus on well-being and happiness [3]. In addition, there is a need for (1) research on the extension of the handprint approach to more holistic sustainability handprint (e.g., taking into account social, environmental and economic handprints of products) [24] and (2) approaches and indicator systems to address the contributions of businesses to the UN SDGs [25]. There are multiple handprint assessment approaches (with potential role to promote sustainability including various perspectives on the world) and more focus is needed on alternative handprint assessment approaches including incorporation of social science understanding of pathways and agency into assessments and methods, tools and data sources [8]. Modern companies can significantly benefit from the development of the sustainability handprint concept [26].
Previous studies have identified many challenges related to both sustainability and handprints, encompassing the integration of (1) sustainability science into sustainability assessment studies [27], (2) social aspects into decision processes due to the fact that social impacts play a major role in sustainability assessment [28] and (3) human needs (interlinked and -twined with other entities such as nature and resources), integrated earth system including its support to well-being and of impacts on human well-being (e.g., health and happiness) into sustainability assessments [29]. In addition, there are challenges related to the implementation of the sustainability concept by most organizations related to the determination and measurement of sustainability performance including selection of social criteria, stakeholder involvement and data availability [30] and to the development of an assessment approach to social sustainability of products and processes due to, e.g., high complexity of the social sustainability dimension, data availability, assessment method issues and acceptance of the approach by the public and the industry [31].

Materials and Methods
This study aimed at exploring, discovering, analyzing and synthetizing the implications of (1) sustainable development, (2) sustainability, (3) social sustainability and (4) societal sustainability definitions and elements for the creation and assessment of social sustainability handprints. In addition, it aimed at exploring, discovering, analyzing and synthetizing the implications of sustainability assessment and sustainability indicator approaches and development focus areas for the assessment of social sustainability handprints. This study, including the specific results sections, is structured based on these specific aims related to both creation and assessment of social sustainability handprints.
In the chosen approach, social sustainability is closely linked to societal sustainability including social/society-environment relationships and interfaces. Interrelationships between social and economic sustainability including social/society-economy relationships and interfaces were beyond the scope of this study. However, many related and intertwined social and societal contexts and aspects are addressed. The materials included scientific books and articles, research reports, online sources and other publications (searched form all major academic research databases) focusing on handprints, sustainable development, sustainability (including sustainability science and research), social sustainability, sustainability assessment and sustainability indicators. This study is accompanied by a previous study (Part (1) [32], which addressed social sustainability handprints in the contexts of handprint and life cycle thinking and approaches. Additionally, there is one simultaneous study [33] that explores social sustainability handprint development in the contexts of both sustainability science and the UN SDGs/Agenda 2030. A similar research approach that is described in this section was also applied in that study.
A qualitative research approach was applied including the application of the following elements [34]: (1) collection and analysis of qualitative information using textual materials, (2) inductive, deductive and abductive reasoning, (3) theory construction (e.g., to promote improvement and provide guidance), (4) organization and synthesis of information and content analysis, (5) a theoretical and conceptual framework that evolves and changes based on new insights and progress of the study, (6) category and pattern construction (e.g., interrelationships, influences and interaction) and (7) summative synthesis and statements (e.g., linkages). Open discovery and insight and new insights and understandings as well as description, analysis and interpretation were also major parts of the approach [34].
The chosen approach acknowledges that there are multiple and diverse approaches to social sustainability handprints including ways to create and assess them. This study links social sustainability handprints with the comprehensive frameworks of both sustainable development and sustainability including numerous sustainability assessment and indicator approaches. Handprint approaches can be, e.g., dynamic and qualitative including focus on actions (e.g., [2,9,11,12]) or static and quantitative [7]. Handprints can be about supporting sustainable development and creating sustainability [3]. Handprint approaches can encompass (1) the good we do with unlimited potential, (2) inspiring, educating and influencing approach, (3) individual and collective creation (at home/work), (4) keeping count of accomplishments, (5) entrepreneurism and (6) recovery, restoration and advocation of protection [11]. In addition, sustainability handprints are about approaches to encour-age people and individuals to work for sustainable development including joint effort to promote a transformation towards a sustainable society and to implement sustainability including focus on, e.g., participation and institutions [12]. Handprint assessments can focus on positive actions and changes (e.g., innovations and initiatives) by organizations, individuals and companies [7].
In addition, handprint approaches can be about (1) solving of societal and environmental challenges, (2) promoting positive changes (e.g., within product life cycles), (3) supporting a sustainability transformation of societies and businesses, (4) assessment of positive contributions to sustainable development (e.g., active contributions of organizations including stakeholder inclusion/education) [25]. In addition, previous research has acknowledged that multiple approaches can be applied to the creation, development and assessment of handprints such as (1) actions to promote sustainability and sustainable development [9], (2) positive/tangible local and global actions towards future sustainability, commitments to act for the common good, care for the planet and all life forms and collaboration to take action for safer and healthier communities [2], (3) positive sustainability contributions, actions and impacts [26], (4) sustainability improvements [8], (5) innovation and collaboration among multiple actors to promote sustainable development [7], (6) innovation in an interconnected world and systemic thinking approaches to sustainability including sustainability management and assessment [6], (7) addressing sustainability challenges and contributions to global sustainable development targets (e.g., Agenda 2030) [5] and (8) holistic approaches to sustainability [24] In addition, social sustainability handprint approaches can be based on, e.g., sustainability management, assessment and indicators (e.g., sustainability indices/indicators [35][36][37]), sustainability science and research approaches and handprint and life cycle thinking and approaches. The chosen approach both builds on and further extends the foundation created by previous research to fully acknowledge the diversity and broadness of the overall social/societal sustainability (including social/society-environment relationships and interfaces), sustainable development, sustainability and sustainability assessment contexts. Therefore, sustainability handprints can be created through multiple ways including (1) innovations, changes, actions/activities, initiatives and positive impacts, (2) sustainability management and assessment (e.g., indicators, index/indices and metrics), (3) sustainability science and research approaches, (4) handprint and life cycle thinking and approaches, (5) leadership, informed decision making, governance, design, planning and sustainable engineering and (5) improvements and changes towards sustainability and sustainable development including, e.g., social/societal sustainability and social/society-environment relationships and interfaces. For the purposes of this study, the social sustainability handprint concept and approach can be presented in a simplified manner as follows: Social sustainability handprint = (social sustainability (normal practice) + social sustainability handprint (social sustainability) ) − social sustainability (normal practice) where Social sustainability (normal practice) refers to the normal social sustainability practices/performance level (that can be used, e.g., as a baseline level of social sustainability) associated with, e.g., an organization, company, society/societal actor, a group of people, individual(s), products/services/processes or an activity/activities based on social sustainability assessment based on, e.g., (1) sustainability science/research approaches, (2) sustainability management and assessment using indicators/index/indices and/or (3) handprint and life cycle thinking and approaches.
Social sustainability handprint (social sustainability) refers to, e.g., actions, innovations, changes, impacts and initiatives that result in the improvement of social sustainability practices/performance level associated with an organization, company, society/societal actor, a group of people, individual(s), products/services/processes or an activity/activities based on social sustainability assessment based on, e.g., (1) sustainability science/research approaches, (2) sustainability management and assessment using indicators/index/indices and/or (3) handprint and life cycle thinking and approaches.

Sustainable Development
Sustainable development is about (1) the creation of conditions for long-term sustainability for present and future generations (e.g., the balance between social justice, environmental protection and economic development and integrated and cooperative solutions to evolving challenges [38], (2) a decision-making strategy by all stakeholders (from local to global level) including sustainability assessment and indicators to address decision-making challenges [16], (3) the promotion of global trends that contribute to the sustainability transition [15], (4) a new vision of empowered stewardship [17] and (5) a sustainable relationship between the human species and its natural life support system and transdisciplinary approaches [8]. Sustainable development can be defined (in addition to the social, environmental and economic pillars) based on what it specifically aims to achieve, how it is measured (including the role of indicators), values supporting or representing it and practice (e.g., goals, indicators and values) [39]. In addition, sustainable development encompasses objective and subjective dimensions of human well-being [18,40] considering the framework of quality of life [40].
Sustainable development is a global challenge within local diversity, capacity and contingency including intergenerational and international dimensions (acting here/now to ensure conditions for high/decent quality of life elsewhere/later) [40]. Additionally, It can be interpreted based on subjective and value-based elements (considering that numerous ideas, observations and concepts from multiple scientific disciplines have created sustainability science) and its important elements include quality of life including sustaining and developing qualities of life [40]. Common visions about the goals of sustainable development focus, e.g., on equitable improvements of human well-being within and across generations [41]. In addition, sustainable development is about (1) a human effort to make choices and institutions to ensure that the earth can support the continued presence of humans for the indefinite future and (2) a vision of how human society could develop sustainably with strong focus on social dimensions such as intergenerational equity [42].
These findings suggest that the creation of social sustainability handprints needs to focus on changes, actions, innovations and impacts that are based on (1) the creation of conditions for long-term social sustainability for present and future generations, (2) integrated and cooperative solutions to evolving social and societal sustainability challenges, (3) help to achieve the defined social sustainability goals, (4) values supporting or representing social sustainability and social sustainability practices (e.g., goals, indicators and values), (5) subjective and value-based elements, sustainability science and common visions about social and societal goals associated with sustainable development (e.g., equitable improvements of human well-being within and across generations), (6) transdisciplinary and future-oriented approaches and inclusion of all stakeholders, (8) the advancement of human well-being and quality of life including intergenerational and international dimensions, (9) building sustainable social/society-environment relationships and interfaces and (10) social sustainability management, assessment and indicators. The implications of sustainable development definitions and elements for the creation of social sustainability handprints are presented in Table 1. whereas the implications for the assessment of social sustainability handprints are presented in Table 2.
In addition, the principles of international sustainable development law include many important issues that should be taken into account in the creation of social sustainability handprints. These principles encompass the following: (1) the duty of states to ensure sustainable use of natural resources (including conservation and protection of the environment such as ecosystems), (2) the principle of equity and eradication of poverty (e.g., inter-and intragenerational equity, just distribution of resources and meeting the basic needs of the poor), (3) the principle of common but differentiated responsibility (e.g., different circumstances, ability to prevent, reduce and control the threat and provision of assistance), (4) the precautionary principle (e.g., precautionary approach to human health, ecosystems and natural resources), (5) the principle of public participation (e.g., people participate in decision-making processes that affect and impact their lives and well-being)) and access to information and justice, (6) the principle of good governance (e.g., rule of law, democracy, political accountability, responsiveness/flexibility of government, democratic/transparent decision-making procedures and institutional structures that promote consensus building, coherence, coordination and community interests) and (7) the principle of integration and interrelationship (e.g., interdependence of social, environmental, human rights and economic/financial aspects, integration at all levels of governance and integrated thinking) [38,[43][44][45][46]. Table 1. Implications of sustainable development definitions and elements for the creation of social sustainability handprints.

Sustainability
Sustainability is a broad and diverse concept encompassing multiple definitions and elements that have implications for the creation and assessment of social sustainability handprints. Sustainability is about normativity (societal and normative choices and social constructions by people based on values), equity (fairness and justice including inter-and intragenerational aspects), integration (whole system perspective and integration of all goals) and dynamism (process of sustainability-oriented change) [20]. The most important elements of sustainability goals vary across places, times and groups and (the adequacy of the resource base to support human well-being now and in the future is a central feature of sustainability) [41]. It has been noted that the UN SDGs provide a mechanism for the communication of themes to activate the social norms that can potentially promote societally beneficial practices [59] and that future orientation is essential for sustainability including all dimensions and measures to address all interlinked impacts on people and the environment [21]. Previous studies have recognized the following characteristics of sustainability: • Important future issues encompass (1) extending the existing metrics to better integrate the contribution of all relevant natural and anthropogenic resources, (2) addressing connections within and across systems organization levels, (3) addressing intra-and intergenerational equity and (4) monitoring of capacities that are necessary for sustainable development (e.g., capacity to measure sustainable development, promote equity and design governance arrangements that support collective management of shared resources and promote equity) [41]. • Based on normative orientation towards sustainability justice (the synthesis of sustainability relationships such as intra-and intergenerational justice between humans and justice towards nature), comprehensive scope, continuance, threefold relationality (nature and present and future generations), uncertainty (especially about the environment and future including interactions between human and natural systems) and limits [60].

•
A dynamic, open and an evolving idea that aims at encompassing multiple interdependence, independence and interpretation possibilities among various sectors, actions, contexts and stakeholders across time and space and a concept that engages with environmental, social and economic domains (key issue is intergenerational equity which refers to fairness across generations) [48].
These findings suggest that the creation of social sustainability handprints needs to focus on changes, actions, innovations and impacts that are based on (1) societal and normative choices, social norms and societally beneficial practices, (2) social construction of people, (3) values, (4) equity, fairness and sustainability justice including interand intragenerational aspects, (5) system level thinking and social sustainability-oriented change processes, (6) the UN SDGs, current and future human well-being and consideration of various places, times and groups, (7) multiple, new and emerging assessment and monitoring metrics and indicators, (8) sustainable social/society-environment relationships and interfaces and (9) interdependence and independence among various sectors, contexts and stakeholders across time and space. In addition, it is essential that the assess-ment of social sustainability handprints includes the application of extended assessment approaches and indicators that better integrate all relevant social and societal aspects (including social/society-environment relationships and interfaces), address new and emerging themes and are capable of assessing and measuring social and societal aspects of both sustainable development and sustainability.
Sustainability challenges are related to almost all aspects of socio-economic systems that require new knowledge and ways to generate and evaluate sustainability [19]. There are multiple definitions and conceptualizations of sustainability [50] and previous studies have recognized that sustainability is (1) a multi-and cross-disciplinary concept [59], (2) an integrative concept (the integration of ecological, social and economic considerations is the foundation of the sustainability concept) [61], (3) a result of interdependencies between societal, environmental, cultural and economic drivers including dilemmas, contradictions and technical problems [62] and (4) a people-centered and conservation-based concept (the development of the standard of human life by respecting the capacity of nature to provide life supporting resources and facilities) that aims at maintaining the environmental carrying capacity [49]. In addition, it has been noted that humanity has not gotten closer to global sustainability despite long-term efforts of sustainability science and associated policy and action programs [63]. Previous studies have also recognized the following characteristics of sustainability:

•
It is based on the social, environmental and economic pillars of sustainability (in the broadest sense) and it encourages coordination between humans and social, environmental and economic pillars of sustainability through sustainability strategies [21]. • A fundamental shift in the development paradigm including focus on enhanced human well-being and environmental resilience [22]. • Governance is needed to implement sustainability in practice and to promote a global sustainability transformation [20]. • It is about a (1) communal system with social equity and understanding of relationship to address the pressures caused by disharmony in the society and (2) the achievement of a stable relationship between human activities and the environment to ensure that future generations can have a good quality of life [21]. • It aims at (1) ensuring that the earth can meet the material and energy needs to support complex systems (e.g., humanity) over the long-term including social dimensions, (2) supporting human society and (3) making the survival of civilized human existence on earth feasible [42].
These findings suggest that the assessment of social sustainability handprints needs to integrate (1) responses and solutions to and the identification and analysis of direct, indirect and underlying reasons for the failure to achieve global sustainability goals (e.g., through policies and actions), (2) new knowledge and way to assess social and societal sustainability, (3) transdisciplinary approaches, (4) diverse ways to define and conceptualize social and societal sustainability, (5) social/society-environment relationships and interfaces, (6) interdependencies between societal, cultural and environmental drivers, (7) the development of the standard of human life through maintaining the environmental carrying capacity and respecting the capacity of nature to provide life supporting resources and facilities, (8) human well-being, good quality of life, social equity, good governance and societal harmony into assessment, development of indicators and collection of information. Further implications of sustainability definitions and elements for the creation of social sustainability handprints are presented in Table 3, whereas the implications for the assessment of social sustainability handprints are presented in Table 4.

Social Sustainability
Social sustainability provides the foundation for social sustainability handprints and it encompasses multiple definitions and elements that have implications in the creation and assessment of social sustainability handprints. Social sustainability is strongly linked to the overall frameworks of both sustainability and sustainable development. Previous studies have acknowledged that social sustainability is (1) a particular branch of sustainable development that addresses its social dimensions and implications (sustainable development originally included a clear social mandate) including its connections to broader bio-physical environmental and economic issues and challenges [92], (2) about the integration of sustainable development dimensions, the incorporation of inter-and intragenerational equity considerations and engagement of the public in the research process (when addressed from the sustainability perspective) [93], (3) both a normative and an analytical concept [94] and (4) essential for sustainability because its constituents and principles promote a more sustainable society and ensure environmental and economic sustainability and system level resilience to manage, e.g., changes [95] In addition, social sustainability can be significantly promoted by the civil society [96] and it is recognized that social dimension is the most challenging pillar of sustainable development including its theoretical, analytical and practical foundations [48]. The main underlying themes of social sustainability can be assessed and monitored by using (social) sustainability assessment methods, tools and metrics including the development of new indicators to address the emerging themes [97]. A previous study has also recognized the following elements of social sustainability: (1) development social sustainability (e.g., meeting basic needs and intra-and intergenerational equity), (2) bridge social sustainability (changing behavior to meet bio-physical environmental goals) and (3) maintenance social sustainability (what can be sustained in social terms and ways of life to be maintained or improved) [92].
These findings suggest that the creation of social sustainability handprints needs to focus on changes, actions, innovations and impacts that are based on and promote (1) social goals, dimensions, implications and aspects of sustainable development including social/society-environment relationships and interfaces, (2) inter-and intragenerational equity, (3) public participation including the application of (social) sustainability research, (4) normative and analytical approaches to social sustainability (e.g., management and assessment), (5) sustainable societies, (6) system level resilience to manage social and societal changes, (7) the essential role of the civil society and (8) ways to meet basic needs, (9) behavior changes and (10) sustaining, maintaining, improving and developing essential aspects of social sustainability and associated ways of life. In addition, these findings suggest that the assessment of social sustainability handprints needs to integrate management, assessment and indicators covering all social sustainability themes and continuously emerging new themes including continuous development of new indicators into assessment, development of indicators and collection of information. Further implications of social sustainability definitions and elements for the creation of social sustainability handprints are presented in Table 5. Whereas the implications for the assessment of social sustainability handprints are presented in Table 6. Table 5.

Societal Sustainability
Societal sustainability is a broad and diverse concept that encompasses multiple definitions, elements and approaches. This concept is also linked to the overall frameworks and both sustainability and sustainable development. Previous studies have recognized that (1) the achievement of socially sustainable societies is an iterative process that simultaneously requires definition of the meaning of the concept, ways to measure the outcomes of action and policy (to assess progress and make adjustments) and necessary conditions for pursuing social sustainability [96], (2) societies can promote a sustainability transition using sustainability indicators to establish or change direction, assess progress and to get warnings of unsustainability [47], (3) the promotion of a sustainable society requires focus on quality of life indicators and social diversity [107] and (4) societal sustainability includes human-ecological relations including establishment and maintenance of long-term integrity of socio-biophysical systems and protection of the life support functions that are essential for both human and ecological well-being [72]. In addition, previous studies have recognized the following important definitions and elements of societal sustainability:

•
Societal sustainability is about (1) sustainability implications of social aspects (e.g., institutions, culture and politics) and their influence on the interaction of social and natural systems and (2) a systems perspective and approach that integrates social and natural systems encompassing consideration of social and environmental quality justice in particular social or economic fields [19].

•
(1) Business organizations are societal institutions that should play a role in ensuring the long-term viability of a democratically governed society that is based on equality, justice and trust and supported by sustainable social, natural and economic systems and (2) organizational management needs to be held accountable by society (e.g., evaluation of outcomes based on criteria that reflect the norms and values of the society) including the use of resources [109].

•
Understanding of the environmental dimension of sustainable development in the context of societal sustainability requires focus on, e.g., biodiversity (ecosystem, species and genetic diversity) and ecosystem services (things acquired by people from nature to support well-being) [48].
These findings suggest that the creation of social sustainability handprints needs to focus on changes, actions, innovations and impacts that promote (1) all aspects of societal sustainability, societal aspects of sustainable development and sustainable societies, (2) consensus-and capacity-building processes and approaches for societal sustainability, (3) the inclusion of multiple stakeholder communities, (4) social diversity and sustainability transitions, (5) sustainable social/society-environment relationships and interfaces (e.g., ecosystem services, biodiversity and life support functions), (6) human and ecological well-being and social and environmental justice, and (7) the contribution of business organizations (as societal institutions) to the long-term viability of a democratically governed society that is based on equality, justice and trust and supported by sustainable social and natural systems. Further implications of societal sustainability definitions and elements for the creation of social sustainability handprints are presented in Table 7. Table 7.

development of indicators and collection of information.

Sustainability Assessment
Sustainability assessment encompasses multiple elements and approaches that have implications for the assessment of social sustainability handprints. Sustainability assessment is based on the sustainability concept within the decision-making context [119] and on context dependent, universal and open-ended processes with intertwined ends and means that contribute to the pursuit of sustainability and to the definition of local sustainability particulars in specific circumstances and contexts [72]. Sustainability assessment is a globally applied tool for directing decision making towards sustainability including a broad and continuously evolving range of processes [119]. Previous studies have recognized that sustainability assessment approaches (1) use sustainability indicators [47], (2) integrate sustainability concepts into decision making through multiple processes [120], (3) support strategic decision making [18] and (4) focus on decision-making processes including assessment of whether, e.g., initiatives, plans or policies will lead society to more sustainable direction [88]. In addition, previous studies have recognized the following important aspects of sustainability assessment approaches:

•
The measurement and monitoring of progress toward sustainability [121] and reflexiveness about issue definition and criteria for sustainable solutions [122].

•
The integration of ecological, social and economic considerations [61]. • Operationalization of sustainability in the context of sustainability assessment including comprehensive considerations and interrelations and interdependency over the short-and long-term and application by governments, civil society organizations and companies at both strategic and project levels [52]. • Multiple approaches to align decision making with sustainability principles (including problem analysis, mapping of options and assessment of alternatives) and operationalization of sustainability for decision making based on structuring of unstructured sustainability issues [122]. • Inclusion of various specific aspects such as (1) intra-and intergenerational equity, (2) socio-ecological system integrity, (3) livelihood sufficiency and opportunity, (4) resource maintenance and efficiency, (5) socio-ecological civility and democratic governance, (6) precaution and adaptation and (7) immediate and long-term integration [72].
These findings suggest that the assessment of social sustainability handprints needs to integrate (1) operationalization of sustainability including direction of decision making towards sustainability and aligning decision making with sustainability principles (problem analysis, mapping of options, assessment of alternatives and structuring of unstructured sustainability issues), (2) context dependent, continuously evolving, universal and openended processes with intertwined ends and means, (3) local sustainability particulars in specific circumstances and contexts, (4) comprehensive considerations and interrelations and interdependency over the short-and long-term, (5) social sustainability indicators, (6) assessment of initiatives, plans and policies (are they leading towards a more sustainable society), (7) ecological, social and economic considerations, (8) progress toward sustainability and criteria for sustainable solutions, (9) application by governments, civil society organizations and companies at both strategic and project levels and (10) specific aspects such as intra-and intergenerational equity, socio-ecological system integrity, democratic governance, precaution and immediate/long-term integration. Further implications of sustainability assessment approaches for the assessment of social sustainability handprints are presented in Table 8. Table 8. Implications of sustainability assessment approaches for the assessment of social sustainability handprints.

Sustainability Assessment Development Focus Areas
There are many sustainability assessment development focuses that have implications for the assessment of social sustainability handprints. The effective use of sustainability assessment and management approaches requires that they are integrated into existing decision making and planning processes or adaptation of other decision-making processes [124]. The design of sustainability assessments need to be based on an integrative process to build a framework for decision making including the integration of social, ecological and economic considerations [61]. In addition, sustainability-based decision making needs to be based on continuous learning, testing, adjustment and development of better understanding about durable and desirable ways of living on the planet [52] considering the complex nature of, e.g., the relationships between human systems and ecosystems [50]. In addition, previous studies have recognized the importance of the following sustainability assessment development focus areas:

•
In-depth knowledge about all parameters that have an effect on sustainability and assessment of the progress of a nation towards sustainability based on all parameters and their individual and combined impacts on all pillars of sustainability [21].

•
(1) The integration, promotion and accomplishment of learning, (2) inclusion of the views of all affected and interested parties in the framing of the assessment and (3) the application of mechanisms for managing trade-offs based on open, accountable and participative approaches [123]. • Design to initiate innovative and creative thought processes to solve sustainable development problems and a communicative process to improve communication about sustainability issues [88]. • Information about (1) ecosystem services, (2) trends in human use of ecosystem services, (3) changes in institutions and governance arrangements and (4) trends in components of human well-being (particular focus on aspects outside traditional measurement) to manage human-environment systems [67].
These findings suggest that the assessment of social sustainability handprints needs to integrate (1) existing and development of new decision making and planning processes and frameworks including integrative aspects, (2) social/society-environment relationships and interfaces including the complex nature of the relationships between human systems and ecosystems and the integration of social and ecological considerations, (3) continuous learning, testing, adjustment and development of better understanding about durable and desirable ways of living on the planet, (4) all aspects, elements and parameters (including their interrelations and individual and combined impacts) that have an effect on and can assess progress towards sustainability, (5) the promotion and accomplishment of learning, (6) inclusion of the views of all affected and interested parties, (7) management of trade-offs based on open, accountable and participative approaches, (8) design and innovative and creative thought processes to solve sustainable development problems, (9) a communicative process to improve communication about sustainability issues and (10) information about changes and trends in human well-being and human use of ecosystem services (particular focus on aspects outside traditional measurement) including social/society-environment relationships and interfaces into assessment, development of indicators and collection of information. Further implications of sustainability assessment development focus areas for the assessment of social sustainability handprints are presented in Table 9. Table 9. Implications of sustainability assessment approaches for the assessment of social sustainability handprints.

(1) The choice of tools and metrics based on highlighted context and characteristics, (2) consideration of the underlying assumptions and features of the applied tools to ensure transparency of the result, (3) the use of a variety of tools based on a choice guided by the assessment context (a good idea because no individual tool can encompass all sustainability perspectives), (4) addressing the lack of capability to assess progress towards sustainability in a holistic way (e.g., focus on multiple social, environmental and economic issues jointly with inter-and intragenerational equity aspects), (5) integration of social, environmental and economic (increasingly also institutional) issues and consideration of associated interdependencies, (6) inclusion of inter-and intragenerational equity considerations, (7) consideration of the future consequences of present actions, (8) acting with a precautionary bias and acknowledgement of the uncertainties related to the results of present actions and (9) engagement of the public [132] Integration of (1) the selection of tools and metrics based on context and its characteristics, (2) the consideration of the underlying assumptions and features of the applied tools to ensure transparency of the result, (3) the use of a variety of tools based on the assessment context to encompass all sustainability perspectives, (4) capability to assess progress towards sustainability in a holistic way (e.g., social/society-environment relationships and interfaces), (5) social, institutional and environmental issues including associated interdependencies, Observation systems that (1) encompass both social and environmental phenomena, (2) include multiple types of information (qualitative, narrative, quantitative data and historical records), (3) support decision making and scientific understanding and (4) address significant changes and assess resilience and vulnerability [67] Integration of (1) observation systems, (2) social and environmental phenomena, (3) multiple types of information (qualitative, narrative, quantitative data and historical records), (4) decision making, (5) scientific understanding, (6) significant changes and (7) resilience and vulnerability into assessment, development of indicators and collection of information (1) Integration into government decision making including recognition of the need to assess the interdependencies between human activities and the environment early in the decision-making process, the need for informed decision-making and participation and openness of the decision makers to a process of change and (2) qualitative approaches that may increase the quality of discussions on the introduction of the sustainable development principles into functioning of societies [88] Integration of (1) informed decision making (e.g., government), (2) early assessment of the interdependencies between human activities and the environment in decision making processes, (3) participation and openness of the decision makers to change processes and (4) qualitative approaches to introduce social and societal aspects of sustainable development principles into functioning of societies into assessment, development of indicators and collection of information

Sustainability Indicators
Sustainability indicators are essential parts of sustainability and sustainable development including sustainability management and assessment. There are multiple sustainability indicator definitions and elements that have implications for the assessment of social sustainability handprints. Previous studies have recognized that (1) sustainability assessment is based on sustainability indicators [47], (2) sustainable development indicators should be selected, revisited and refined based on the appropriate communities of interest [134], (3) reaching sustainable development requires the use of indicators taking into account all views, issues, actions and diversities (a sustainable development indicator system is an essential platform) [48], (4) the transition towards sustainability takes place through the application of a new set of values-based indicators to measure the implementation of ethical principles [71] and (5) multiple sustainability indices address community, environment and economy parts of sustainable development and their interactions [135]. In addition, previous studies have recognized the following important aspects of sustainability indicator approaches:

•
Internationally negotiated consensus on priority human needs goals, targets and indicators as a basis and focus on the assessment of the achievement of goals and targets and of progress towards or away from a sustainability transition [64].

•
(1) Support of decision making for and to promote sustainable development, (2) operationalization of sustainable development for a specific system in a particular socioenvironmental context, (3) generation and communication of complex sustainability information (well-structured approach to inform decision making), (4) identification of knowledge and data gaps and (4) advancement of continuous social learning (decision makers and stakeholders) [16].

•
(1) Assessment and communication of the progress toward sustainable development, (2) support of all levels of decision making and policy processes (e.g., strategies, policies, plans, operations, activities, programs and projects) and (3) improvement of the management of both human and natural systems [128]. • Identification (including making them visible) and management of essential dimensions of society and the environment [71].

•
(1) Mapping progress toward meeting human needs (including specific indicators of human welfare) and preserving life support systems, (2) evaluation of the effectiveness of applied actions to achieve the goals, (3) informing the society about the nature and progress of the sustainability transition and (4) contribution to information feedback system of society to adjust directions, assess progress and gain unsustainability warmings [58].
In addition, sustainability indicators are about the provision of information to support decision making about, for example, the future directions of society [53] and an important policy making and public communication tool including information on national and corporate social, environmental and economic performance [134]. They are also tools to identify and enable the management of society and environment related dimensions and progress towards sustainability (change in dynamic systems) including addressing challenges such as climate change and resource limits [71] and a part of the institutional framework for sustainability to assess and monitor progress and value [75]. Sustainability indicators can be based on multiple qualitative, quantitative or combined approaches and used to, e.g., report on and communicate about sustainability and to measure the characteristics or processes of the human-environmental system to ensure its functionality and continuity far into the future [53]. Previous studies have also recognized that sustainability indicator approaches encompass the following important aspects:

•
(1) Promotion and support of decision making for sustainable development, (2) provision of guidance towards a sustainable society, (3) addressing sustainability decisionmaking challenges including interpretation (principles and socio-environmental context), information-structuring (complex and multi-dimensional sustainability into, e.g., indicators) and influence (of sustainability information on decision making and implementation of sustainable development), (4) interpretation of sustainability, (5) impact measurement and (6) promotion of social learning, debate and participation [16]. (1) Sustainability transition through the operationalization of goals into specific indicators that can be continuously monitored, evaluated and reported, (2) responsibility by societies to take measure of the desired development direction and (3) sustainability transition reporting based on multiple indicators to both map progress toward the associated goals (meeting human needs and preserving life support systems) and to evaluate the effectiveness of applied actions to achieve the goals [58].
These findings suggest that the assessment of social sustainability handprints needs to integrate (1) social sustainability indicators and indicators for social and societal aspects of sustainable development based on the appropriate communities of interest, (2) the application of indicators taking into account all views, issues, actions and diversities, (3) the application of a new set of values-based indicators to measure the implementation of ethical principles, (4) multiple sustainability indices that address community and environment parts of sustainable development including social/society-environment relationships and interfaces, (5) internationally negotiated consensus on priority human needs goals, targets and indicators, (6) the achievement of goals and targets and of progress towards or away from sustainable development, a sustainability transition, meeting human needs and welfare and preservation of life support systems, (7) informed decision making, the identification of knowledge and data gaps and continuous social learning, (8) management of essential dimensions of society and the environment, (9) societal information feedback system to adjust directions, assess progress and produce unsustainability warmings and (10) information about the future directions of society into assessment, development of indicators and collection of information. In addition, the following aspects need to be integrated into social sustainability handprint assessment approaches including development of indicators and collection of information: • Corporate social and environmental performance and management of society and environment related dimensions and progress towards sustainability (change in dynamic systems) including climate change and resource limit challenges. • Institutional framework for sustainability to assess and monitor progress and value and sustainability indicators based on multiple qualitative, quantitative or combined approaches (e.g., to assess the characteristics or processes of the human-environmental system to ensure its functionality and continuity far into the future).

•
Assessment of what really matters to track progress toward a sustainable society and societal values and individuals as leading actors in the collection, analysis, evaluation and communication of sustainability information and data (e.g., households, daily activities and urban/rural ecosystems).
The assessment of social sustainability handprints also needs to integrate (1) decision making for sustainable development, provision of guidance towards a sustainable society and social learning, debate and participation, (2) the operationalization of goals into specific indicators that can be continuously monitored, evaluated and reported, (3) assessment of the desired development direction by societies and (4) sustainability transition reporting based on multiple indicators (to assess progress toward meeting human needs, preservation of life support systems and the effectiveness of applied actions to achieve these goals) into assessment, development of indicators and collection of information. Further implications of sustainability indicator approaches for the assessment of social sustainability handprints are presented in Table 10. Table 10. Implications of sustainability indicator approaches for the assessment of social sustainability handprints.

Sustainability Indicator Development Focus Areas
There are many development focus areas related to sustainability indicators and continuous development, innovation and responses to emerging issues are highly important. Previous studies have recognized that (1) the development of sustainable development and sustainability indicators needs to address action towards change and improvement of the quality of human lives [17], (2) there are both objective and subjective approaches to sustainability indicators and of shortcomings related to any statistical means to address complex truths [137], (3) the development of new sustainability indicators is focusing on the measurement of emerging themes and that too narrow assessment approaches are harmful for a meaningful progress in social sustainability assessment [100], (4) the development of sustainability indicators and indices should take into account their use and the needs of users [135] and (5) the users of sustainable development indicator metrics must have understanding about the foundations of specific metric including its limitations due to various definitions and conceptualizations of sustainability [50]. In addition, previous studies have also recognized the following important sustainability indicator development focus areas:

•
Capturing of social, environmental and economic priorities of projects and conflicts between human well-being, environmental conservation and economic development [139].
• Human-environment vulnerability including indicators that monitor the combination of social and natural factors that lead to irreversible damage [58]. • Indicators of (1) progress towards sustainability and (2) change in dynamic systems to address challenges (e.g., climate change and resource limits) [71]. • Specific issues such as (1) equity, (2) awareness of sustainability, (3) participation and (4) social cohesion dimensions of the social-environmental framework (for the analysis of organizations) [103].

•
The development of a concise set of fully integrated indicators covering essential sustainable development variables that define the main minimum set of social, environmental and economic monitoring measurements to link across actors, sectors and countries to promote monitoring, accountability and data for the implementation of sustainable development goals [51].
These findings suggest that the assessment of social sustainability handprints needs to integrate (1) the development of sustainable development and sustainability indicators that address action towards change and improvement of the quality of human lives, (2) objective and subjective approaches to sustainability indicators, (3) the development of new sustainability indicators and indices to assess all emerging themes considering their intended uses and the needs of various users, (4) the promotion of the understanding of various users about sustainable development indicators and metrics including limitations due to various definitions and conceptualizations of sustainability, (5) social/societyenvironment relationships and interfaces including social and environmental priorities of projects and conflicts between human well-being and environmental conservation, (6) human-environment vulnerability including indicators that assess the combination of social and natural factors that lead to irreversible damage, (7) indicators of progress towards sustainability and of change in dynamic systems to address climate change and resource limit challenges, (8) the assessment of organizations based on equity, awareness of sustainability, participation and social cohesion dimensions of the social-environmental framework and (9) the development of a set of fully integrated indicators to implement sustainable development goals based on reliable sources of information and covering essential sustainable development elements (that define the main social aspects and aspects related to social/society-environment relationships and interfaces including linkages across actors, sectors and countries) into assessment, development of indicators and collection of information.

Conclusions
The findings of this study suggest that social sustainability handprints provide significant potential to advance both social and societal sustainability based on the overall frameworks of both sustainable development and sustainability including the promotion of more sustainable social/society-environment relationships and interfaces. Social sustainability handprints can be created through multiple actions, changes, innovations and impacts to promote social sustainability based on sustainable development, sustainability and social and societal sustainability. Various actors such as all types of organizations, individuals, groups and companies can implement these ways to create social sustainability handprints. In addition, there are multiple assessment approaches that can be applied to the assessment of social sustainability handprints such as sustainability management, assessment and indicators, sustainability science and handprint and life cycle thinking and approaches. All these approaches contribute to improved social sustainability management based on social sustainability assessment and can be applied by all types of organizations.
In brief, the studied frameworks provide numerous ways to create and approaches to assess social sustainability handprints that can be used and further developed by multiple actors such as all types of organizations. Future research should focus on further theoretical and practical development of the creation of social sustainability handprints in the contexts of sustainable development, sustainability and social and societal sustainability. In addition, future studies need to pay similar attention to the development of the assessment of social sustainability handprints in the contexts of sustainability assessment and sustainability indicators. This theoretical and practical development needs to address all ways to create social sustainability handprints such as changes, actions, innovations and impacts and all assessment approaches such as sustainability science, sustainability management, assessment and indicators and handprint and life cycle thinking and approaches. Transdisciplinary approaches and real-life case studies based on continuous social and societal learning are highly recommended for this kind of future research and development.
