In September 2015, at the UN headquarters in New York, the international community agreed on a set of 17 Sustainable Development Goals (SDGs), which simultaneously included 169 goals to be achieved by 2030. The SDG framework has a specific objective for education (SDG4—Ensuring inclusive and quality education for all and promoting lifelong learning) and makes explicit reference to higher education, although only this “ensures equal access for all women and men to access and quality technical, vocational and higher education, including university” (SDG4 objective 4.3) (UNESCO, 2018a).
The first comprehensive intervention for the integration of CSR on academic education in Europe was in late 1980s by Professor Mahoney in the form of a comparative study on the teaching of business ethics in the U.S.A., U.K. and Continental Europe (Mahoney, 1990). Following that, numerous articles have been written about education for Sustainable development and CSR education in Higher Education Institutions. The majority of the earliest studies have focused their attention on the economic universities or schools of business. A considerable number of relevant and interrelated specific issues can be found, for instance the relation between marketing and business ethics (Shannon & Berl, 1997), the sustainability (Weber, 1990; Huckle, 1999; Wheeler et al., 2001) or the evaluation criteria for courses of business ethics (Moon & Matten, 2004). The success of these actions is being determined by companies, E.U. and by other international bodies and it can be considered, amongst others, a result of the human factor, who has been trained by various training programs in universities (Benn & Kramar, 2011; Ceulemans et al., 2011) and technological institutes (Wright, 2003; Cantalapiedra et al., 2006; Benn & Rusinko, 2011). The goal of these earliest programs, often referred to in the international literature as training programs for corporate social responsibility and programs for environmental (and ecological) education and sustainable development, is to prepare employees, future managers and active citizens to improve social, environmental and sustainable business performance (Wright, 2002).
Recently, international organizations, university associations and corporations but also Higher Education Institutions (HEIs), have embraced Education for Sustainable Development (ESD) and CSR management (GUNi, 2017). HEIs have also introduced courses concerning CSR and business ethics in their curriculum (UNESCO, 2018b). It appears that these organizations have identified the need and importance of students’ knowledge, perceptions and behaviors on social, ethical and environmental issues (Leal Filho et al., 2017, 2018; Lozano et al., 2015, 2019).
Investigating the global literature in depth, it is worth mentioning the strong correlation between the concept of Education for Sustainable Development and CSR. The need of CSR philosophy was emerged mostly after the 70’ in order to confront crucial issues, such as environmental scandals, the Climate Change, the Ozone Layer, the protection of biodiversity and to constrain the environmental degradation. Thus, Higher Education Institutions have been introducing subjects concerning Business Ethics, Environmental protection, CSR management, in many academic fields but mostly in Business Administration, firstly at undergraduate level and then at post-graduate level, so as to introduce and promote Sustainable Development Goals.
For these reasons, it is imperative that the Greek students’ education on issues regarding CSR and Sustainable Development is crucial so that they have the necessary knowledge, skills and abilities to cope with the changing Greek market needs. Institutions of Higher Education have a very important role to play in sustainable development goals. They should investigate the needs and Greek market trends and try to adapt their curriculum properly so as to provide the necessary knowledge to academics, but also to shape an appropriate behavior and culture on social, environmental and corporate governance responsibility.
However, the question that arises from the above is whether Greek universities have embraced the corresponding actions. The lack of literature on Sustainable Development and Corporate Social Responsibility Policy in Greek Higher Education Institutions, further reinforces the need for research Sustainable Development and CSR in the Greek HEIs.
2. Education for the Sustainable Development and CSR in the HEIs—Literature Review
Interdisciplinary researches on the mainstreaming of CSR into European universities, highlight business ethics (Rossouw, 2002), social dimensions of entrepreneurship (Cummins, 1999) and instructional technics of CSR (Cowton & Cummins, 2003) as priority areas. Research appears to be mainly focused on the scientific field of business ethics in different departments (Van Luijk, 2001; Hartman & Hartman, 2005). Illustrative examples of such departments are, business administration, mechanical engineering, information technology, architecture, tourism, etc. (Fien, 2002; Wright, 2003; Down, 2006).
Moon & Matten (2004) suggest that the overall development of education in CSR is not a result of academic research but of other numerous sources. It is also noted that CSR, in the broader sense, is high on the agenda of the learning procedure with the teaching courses for CSR being mostly by the interest of industry rather than the academia (Moon & Matten, 2004). Furthermore, the integration of actions related to sustainable development in the field of education, within the cooperation framework of central public administration with companies, is fairly recent and rather limited (Moon & Orlitzky, 2011). Another important indicator of the relevance between CSR and schools of Economics and Business Administration is the way of finance of this new scientific field (Ceulemans et al., 2011). Moreover, there has been a debate on whether CSR should be taught as a separate course in the curriculum or if a new program supporting the basis of the concept and content of CSR is to be created (Christensen et al., 2007; Rusinko, 2010). The issue at hand, namely environmental protection awareness, is becoming exceedingly important to students considering the ongoing economic and environmental crisis (Sims & Felton, 2006; Posch & Steiner, 2006; Lourdel et al., 2007). In fact, a number of universities around the world have introduced courses in their curriculum regarding environmental protection, environmental ethics, social responsibility and other related subjects. Indicative examples are universities in China (Niu et al., 2010), Russia (Lindroos, 2001), Jamaica (Down, 2006), Austria and Sweden (Anderberg et al., 2009) and Spain (Setó-Pamies et al., 2011). As a result, business ethics have experienced an exceptional boom in the field of Higher Education and similar courses have become more well-known and attractive at both undergraduate and postgraduate levels. Christensen et al. (2007) observed that 42% of the best MBA programs have incorporated courses on CSR. Similarly, International Schools of Business Administration have begun implementing social and responsible initiatives to educate future leaders, managers and employees in preparation of them facing environmental, social and economic systems throughout their careers and crucial issues around these areas (Deale et al., 2009; Stubbs & Schapper, 2011).
In the Greek universities, Macris & Georgakellos (2006) support a new teaching tool in education for sustainable development: ontology-based knowledge networks for environmental training. In the technical universities, Manoliadis (2009) promotes a set of multidisciplinary case studies and support material in order to aid engineering students in understanding the sustainability concepts and how solutions can be developed. Moreover, Sepetis & Rizos (2011) conducted, for the first time, a research about the promotion of Education in the Sustainable Development in Greek HEIs.
Due to the lack of an institutional framework requiring universities to incorporate sustainable development policies, all best CSR practices and actions have been a result of voluntary initiatives. In sustainable university level, the study of Professor Idowu (2008), examined whether the universities of U.K. are implementing CSR in their business operations. The research shows that most institutions of higher education in the UK are conscious that they owe some responsibility to their stakeholders and are striving to demonstrate this awareness in various ways (Idowu, 2008). A survey by Nejati et al. (2011) shows the effects and benefits of CSR integration for the top 10 universities worldwide. The findings of this research show that world leading universities are committed to their social responsibility and provide sufficient information on most of the core areas of corporate social responsibility (CSR) (Nejati et al., 2011). Moreover, research in the Canadian universities by Elliott and Wright in 2013 concluded that while a number of themes emerged, one that was overarching as a general concern and both a barrier and incentive to a more sustainable university was university finances. This in turn is linked with the students through enrolment and recruitment efforts as tuition represents a large proportion of university budgets. Participants believed that students hold the greatest ability of all university stakeholders to promote sustainability on their campuses and when combined with their ability to impact university finances, the possible impact of empowered students to initiate change for more sustainable campuses is great (Elliott & Wright, 2013). According to Hoover and Harder in the field of sustainable universities, there have been different attempts to conceptualize the characteristics of a sustainable university (Hoover & Harder, 2014). Thus, a sustainable university entails changing its own mission, redefining curricula, modifying its research programs, integrating new ways of living in their campuses, enhancing social engagement and intervention, and evaluating and announcing these activities Lozano et al. (2015). Moreover, Ceulemans et al. (2011) argue that the topic of Sustainability Reporting (SR) has been approached in a rather fragmented way in the Higher Education for Sustainable Development (HESD) literature, while the scientific field would benefit from more in-depth studies, preferably supplemented by empirical evidence. For this reason, the concept of SR in relation to HESD was until now relatively unclear, and many avenues for further research currently still remain open (Ceulemans et al., 2011). Verhulst & Lambrechts (2015) presented a conceptual model which links human factors to the sustainable development integration process. The model structures and supports the analysis of this integration process in a higher education institution. It is applied in a specific case study of a Belgian university college. The results indicate that the conceptual model helps to get a profound understanding of human related barriers for integrating sustainable development in higher education, as well as to understand the underlying reasons for these barriers and linkages between them in different stages of the integration process. Another main lesson learned is the importance of continuously supporting ambassadors of sustainable development integration in higher education (Verhulst & Lambrechts, 2015). A recent study in the Portuguese university students by Aleixo et al. (2018) results suggests that, although aware of the concept of sustainability, the different stakeholders are not familiar with the concept of sustainable higher education institutions. The lack of financial resources due to the decline in funding for higher education and falling numbers of Portuguese university students is perceived as the main barrier to sustainable development in higher education (i.e. practices are still associated with spending financial resources). This research highlights the importance of a conceptual and organizational change in higher education institutions, notably through identifying new sources of financing, more flexible organizational forms, more comprehensive mission statements, more tailored educational offers, life-long learning and commitment to internationalization, and more strategic human resource management (Aleixo et al., 2018).
Further research by Karatzoglou (2013) argues that the published ESD research covers a wide range of regions, topics, methodologies, and findings. The prevailing methodological approaches include theoretical and case-study articles. Yet, the former suffer from a rigorous conceptual framework deficiency, while the latter are characterized by their descriptive nature, which can be inspiring and encouraging for future peer efforts but of limited added value to theory development (Karatzoglou, 2013). Across the world, but particularly in Europe, some universities have become leaders in the field with very good practices. But unfortunately, many of those efforts address only one or two of the sustainability domains at HEIs, which continue to foster compartmentalization, instead of a holistic approach (for instance an approach which is inclusive and takes into account inputs and knowledge from different subjects) and a systems thinking approach (Ramos et al., 2015). Lozano et al. (2015) conducted an exploratory literature review to identify the different practices and domains among HEIs within sustainability, and the results revealed that most are focused on education (including curricula, pedagogies, competences and “educating the educators”), followed by campus operations, institutional framework, outreach, and assessment and reporting (Lozano et al., 2015). Recent research by the same authors (in 1997, 2015 updated the theoretical framework) provided a more precise perspective on how sustainability competences can be better developed in class, and how to better develop all the sustainability competences (Lozano et al., 2019). In the following chapter an empirical research will take place, in order to examine the relationship between Sustainable Development and CSR policies in HEIs in Greece.
3. Education for the Sustainable Development and CSR in the Greek Higher Education Institutions
Although very little has been done on Sustainable Development Education in Greek universities in relation to the interaction of other international universities in this field, we must admit that Greek higher education institutions are in a unique position to guide the implementation of each Goals for the Sustainable Development from different areas of education, work and action in the Greek business community and Greek society. Greek universities have long been powerful drivers of change both locally, regionally and globally and can support SDGs in thousands of ways in the Greek market. In addition, some Greek higher education institutions have already begun to implement and incorporate the concept of sustainability and CSR management into their universities, institutions, curricula and strategies. Educational authorities have begun to implement and integrate the concept of sustainability into their campuses, institutions, curricula and strategies. Moreover, international, European networks and statements on sustainable development have been created or promoted in existing Greek university networks. The main question that arises is if the introduction of these subjects has contributed to social and environmental protection in the Greek Universities and if Greek HEI’s students have altered their way of thinking and operating. To reach to a conclusion, a survey was conducted from an indicative sample of Greece HEI’s that have implemented courses about Sustainable Development and the CSR.
3.1. International, European and Greek Conventions and Declarations in the Field of Education for Sustainable Development and CSR Policies in HEIs
The development of Sustainable Development Education in the HEIs statements has increased both in terms of intensity and scope, as well as the intensification of the interaction between government and university statements. The interaction between university and supranational institutions indicates that in education and research policies sustainability has gained increased attention. This has produced an effect at least in three different ways. In the first place, the parties seem to internationally agree on the universities’ role and function in sustainable development. In the second place, the Sustainable Development Education in the HEIs declarations have formed the basis for the adoption of national legislative measures, e.g., in Germany, the UK and the U.S. In the third place, the competition among universities on green campus performance has emerged (Grindsted, 2011).
Today’s likewise, universities in Europe and around the world are playing a crucial role in global sustainable development goals. The Association for the Advancement of Sustainability in Higher Education (AASHE) was established in 2005 to “help coordinate and strengthen campus sustainability efforts at regional and national levels, and to serve as the first North American professional association for those interested in advancing campus sustainability”. The AASHE also recognizes colleges and universities that have achieved the greatest level of success with green initiatives on-campus and within their surrounding communities. The association gauges these efforts using the Sustainability Tracking, Assessment & Rating System (STARS), a voluntary system that allows different colleges and universities to report trends and track their sustainability efforts. The European Universities Association (EUA) is dedicated to the international cooperation for sustainable education. Therefore, it is natural that the Association is an active part of the worldwide agenda for achieving the United Nations’ Sustainable Development Goals (SDGs). The European Universities contribute to the goals through research and education in a wide array of disciplines that can potentially contribute to a better future. In a complex and developed context like Europe, it is essential that the achievement of the Sustainable Development Goals rests on knowledge, new research, innovation and citizens who are empowered by critical thinking1. Recently the Global University Network for innovation (GUNi) presented their latest publication, “implementing the 2030 Agenda at Higher Education Institutions: Challenges and Responses”. The publication focuses on the obstacles that higher education institutions encounter when implementing the Sustainable Development Goals and offers some clues as to what some higher education institutions do to overcome them (GUNi, 2018).
In July 2018, Greece presented its first Voluntary National Review (VNR) at the 2018 UN High-Level Political Forum on Sustainable development (HLPF). This VNR report covers all 17 SDGs2 through eight National Priorities for adapting the SDGs to national needs and circumstances, also in line with the above mentioned National Growth Strategy. These eight overarching National Priorities have been defined, through an open dialogue within all government units and with a wide array of stakeholders, and by an in-depth mapping exercise carried out in 2017. One of the eight National Priorities focuses on “Providing high-quality and inclusive education”, linked to SDG 4, and covers inter alia all aspects pertaining to ESD. The UNESCO Global Action Plan on ESD (GAP) provides the overall framework for ESD implementation in Greece, linking policies and activities with the UNECE Strategy for ESD, as well as the Mediterranean Strategy on ESD and its endorsed Work Plan3. In this context, the Hellenic Ministry of Education is promoting policies and measures at all education levels, for the integration of the basic principles of sustainable development, in line with the overall national education policy, and is implementing concrete interventions at all levels of education, supported by a number of laws and Ministerial Acts, to this end (UNESCO, 2018b). Many national and international declarations to promote sustainability have been developed in the university sustainable education, and many universities have voluntarily signed several initiatives and statements over the last thirty years (Lozano et al., 2015, 2019). However, signing a statement does not imply significant progress in the field of sustainability (Dlouhá et al., 2018).
3.2. Education for Sustainable Development in Greek Universities
A very encouraging fact is that Greek HEIs have introduced courses concerning business ethics, Sustainable, Environmental and CSR into their curriculum, following the trends and needs at an international level. The initial step was made mainly by Greek Schools of Economics and Business Administration, which have implemented courses, first in post-graduate level and then in undergraduate level. Some indicative examples of Greek HEIs are demonstrated in the next Table 1.
Taking into account that the role of higher education institutors in Greece is being formed not only from the transportation and transmission of knowledge, but also from the shaping of responsible citizens, it is worth to mention three successful cases of Greek universities that have developed important activities in
Table 1. Some Greek HEIs courses concerning business ethics, sustainable, environmental and CSR into their curriculum. Source: owns elaboration.
3.3. A Research in the CSR in Business Education in the Greek Universities
The research has been presented first time in the “ENVECON 2014” under “Corporate social responsibility and environmental management policies in higher education” by Sepetis and Rizos and took place during 2014 from various Schools of Business Administration of the Greek Higher Educational Institutions. Our sample though was mainly from the Technological Educational Institution (TEI) of Athens and the University of Piraeus (Sepetis & Rizos, 2014). The program used for data processing was the statistical program SPSS17.0 and the analysis presented below used the descriptive statistics. The survey involved 220 students, of which 76 individuals were male (34.5%) and 144 were female (65.5%) (Table 2) (Figures 1-8).
Some of the limitations of the survey were the small sample and the few participated HEI. Mainly, it involved two Greek Higher Education Institutions, both in Business Administration area. In the near future, the survey will be extended in more Greek HEI, so that more reliable data and results will be derived, presenting the actual condition in Greece. Moreover, it will investigate the proportion of students that are willing to get employed in organizations that perform CSR actions, conduct sustainability reports or CSR reports. One final field of investigation is whether students will prefer postgraduate programs about CSR and if they believe that they are going to be value-added in their business career. The encouraging fact is that CSR is well-accepted to both students and Greek HEI and is seen as an idea and philosophy whose time has come.
4. Research Findings and Discussion
The first CSR research in Business Education in the Greek University was in 2003 by Walker and co-authors, entitled: “An investigation of CSR orientations among Greek University students”. In this paper the researcher found that there are strong parallels between the CSR orientation of Greek students and managers in other countries, suggesting that culture may have little bearing on the corporate social responsibility orientations. The findings, in this sense, belie some of the stereotypical images of Greek culture and business practice in Greece (Walker et al., 2003).
Almost ten years since this research for CSR in Greek universities, the research of Sepetis & Rizos (2014) concluded that Greek students in the Greek business schools have knowledge of CSR at a relative level with European Universities or other international universities. According to this research regarding the question, if Greek students are familiar with the term of CSR, 87% answered positively, while only 13% responded negatively. Also, 40% of them knew the meaning of CSR from their educational institution. These findings are particularly interesting as students seemed to already have a first contact of this new way of business operation and Greek HEIs have contributed to this fact by introducing courses on CSR. It is noteworthy that regarding the concept of CSR, 32.4% of the Greek students understand CSR as a matter of Corporate Responsibility, 23% of environmental management issues and less of charity and legal issues. Furthermore, 45% of the sample believes that CSR is one of the most important subjects
Table 2. Research has been presented first time in the “ENVECON 2014” under Corporate social responsibility and environmental management policies in higher education by Sepetis and Rizos Source: owns elaboration.
for their academic and professional development in the social and environmental issues and 43% supports that CSR courses have helped them in the development of responsible behavior as future managers. Therefore, it is observed that CSR, which has been taught in the Greeks universities is a philosophy, which emphasizes on the responsibility towards the society and on the environmental protection and contributes to Sustainable Development. In addition, students were asked why CSR concerns them and responded that as future CEOs or employees, CSR could be useful and very important in the future business market for: 1) future business operation; and 2) social reputation of companies; 3) future human resources; 4) social sensitivity and environmental issues. Finally, students were asked to give their personal opinions and proposals on how Greek Higher Education Institutions can contribute to environmental protection. The main recommendations that were made is the introduction of CSR courses in the curriculum, so that academic citizens will shape a proper perception towards CSR and also this perception will be transmitted to academic staff and professors in order to, gradually, integrate the new philosophy in order to be applied by HEIs operations. Moreover, students consider that HEI should implement control energy use, as well as the implementation of environmental management systems (ISO, EMAS, etc.). An additional recommendation is the commitment of HEIs for recycling and the use of recycled materials in every activity. Furthermore, students suggest the planning of informative events and actions for the protection and restoration of the environment (volunteering, planting, etc.) inside their university so as to inform the academic society about the eco-friendly policies. According to the sample, these recommendations will greatly contribute to the integration and adoption of CSR-oriented and environmentally friendly behaviors across the academic community in collaboration with the business community (Sepetis & Rizos, 2014). Nikolaidis & Efthymiadis (2016) concluded that students should not only take courses about CSR, but they should become more actively involved in various CSR activities. Companies could play a significant role at this point, by allowing students to participate in their CSR initiatives. In Greece, despite some initial progress, there is still a long way to go as far as CSR educational programs are concerned (Nikolaidis & Efthymiadis, 2016). Pitoska et al. (2018), analyze the dominant perceptions of stakeholders towards CSR in HEIs, a qualitative empirical research, which was conducted in the region of Northern Greece, via online structured questionnaires. Their results demonstrated that there are differences in CSR perception and understanding among the surveyed stakeholders. It is worth noting that the majority of the participants were aware of the actual meaning and purpose of CSR, as well as of the potential benefits from its implementation. Most of the stakeholders considered CSR as a contemporary concept, related to environmental and social aspects, company profitability, legislative framework, voluntary work and charity as well as sustainable development. In addition, the research highlighted that it is vital that Greek HEIs incorporate CSR or business ethics in their curricula (Pitoska et al., 2018).
Finally, the Greek research’s in the Greek Education for the Sustainable Development and CSR and recent relevant research’s for Leal Filho and Lozano and co-authors confirm the hypothesis of Walker and co-authors that “there are strong parallels between the CSR orientation of Greek students and students and managers in other countries”. According to the international research in the field of Higher Education for Sustainable Development by the Leal Filho, and to other researchers in a 2017 explorative study about the fundamental obstacles to implementing sustainability at universities there have been successful developments in the field of Higher Education for Sustainable Development over the past 15 years or so and there are still numerous challenges to overcome. Among these challenges is the need for Higher Education Institutions to improve the integration of sustainability in the curriculum and in research, and most important, to integrate it holistically in their systems (Leal Filho et al., 2017, 2018). In the same research field, a paper that focuses in the European Universities by Lozano et al. (2019) suggests that although there has been considerable progress in the incorporation of Sustainable Development into the curricula of higher education institutions (HEIs) in Europe, particularly on competences for sustainable development and on pedagogical approaches, there has been limited research though on the connection between how courses are delivered (pedagogical approaches) and how they may affect sustainability competences (Lozano et al., 2015, 2019).
HEIs staff in Greek Universities and especially professors should provide students, not only with the skills and training they will need in their future business careers, but they should also make them understand how crucial and vital decision making in social, environmental and corporate governance issues within an organization is. Every wrong and right decision has an impact. Greek students will be future managers, CEOs and future employees and will be responsible for the shaping of business principles, values, policies and strategies, which should be sustainable, socially, ethically and environmentally responsible.
From the business side, since 2000, research has shown the growing desire of international and Greek students to incorporate CSR into university education in collaboration with the business community. In addition, many researchers point out that the promotion of such educational programs requires the requisite demand from companies and civil society organizations to develop an ethical awareness in education. Therefore, the Greek Business Schools supporting Sustainable Development Goals and CSR will have a strong interest in further collaborating with the business community in a number of ways, summarized:
● Collaboration with companies for the training of students in CSR business practice;
● Develop SDG-related exchange programs between universities and businesses;
● Develop “proof-of-concept” SDG solutions for take-up by business;
● Arrange innovation challenges to address the SDGs for researchers across the university and external stakeholders;
● Encourage processes to assess the impacts of proposed solutions on all other SDGs and seek to maximize co-benefits and minimize negative impacts;
● Development of researches on SDGs and CSR in small and medium sized companies;
● Development of educational tolls for lifelong learning and e-learning in business ethics, on SDGs;
● Development of operational tools of sustainable development, such as environmental accounting and social accountability reports (CSR index, GRI reports);
● Development of partnerships for the implementation of quality systems and environmental or social management and corporate governance issues (ESG).
● Collaborate with businesses’ community to develop new technologies and solutions to address the SDGs;
● Establish innovation hubs focused on SDG-related challenges, partnering businesses and university based research;
● Incubate start-up high-tech companies associated with university research programs inspired by the SDGs and evaluated by their contribution to the SDGs.
A major recommendation in the field of Higher Education Institutions for Sustainable Development and CSR strategies is that universities should establish formal structures to guide the implementation of social, environmental and corporate governance management in the operational level of the university. Moreover, sustainable development policies and CSR programs, in Greek Universities, specifically in Business Schools should be supported with specific academic personnel, instead of trying to pursue them on an ad hoc with current academic staff basis, as is seen in many cases. In addition, the areas of CSR management and the integration of sustainable development goals into the business community are major obstacles in a day-to-day business operational management. For this reason, we follow the lack of interest of companies in the issue of CSR or their concern for sustainable development issues. The lack of business structures, such as the social and environmental sector in companies responsible for ESG issues (for instance GRI reports) also contributes to the problem of SDGs in the Greek business community. To achieve these goals, today’s most of the Greek companies plan training programs with business consultancies and other NGO organizations, which usually prepare their employees in order to assist with the implementation of the aims of the corporate social responsibility, environmental policy and corporate governance issues. On the contrary, in this paper we support that sustainable development education and CSR programs should be incorporated into Greek university business schools and should be supported by the Greek business community and educate future CEOs and employees on Sustainable Development Goals.
This study has been done within the framework of the Postgraduate Health and Social Care Management Programme of the University of West Attica.
