The aim of the research and investigation methodology was based on an expert survey, using questionnaires translated into German, English, French, Spanish and Portuguese languages. The experts, interviewed in this study as part of the international community, represent institutions or organizations, that are involved in educational policy or in university research and teaching contexts with the topics and content as well as the implementation of ESD. The answers of the experts provide a different and wide range of variations in assessments of the implementation of the UN Decade and its characteristics of democratic potential and support. This shows that the potential democratic influences can always be assessed much more positively through sustainable development than that of actual democratic changes, particularly in reference to good governance, to the basic and human rights, to the protection of minorities, to civil society participation and to the separation of powers and the rule of law.
