Introduction
At the Rio+20 conference the cooperation between science and policy was highlighted. A full list of recommendations was given in the “The Future We Want” outcome document, expressing the need for strengthening the collaboration between science and policy as well as the necessity of fostering international research collaboration so as to support sustainable development of society in the near future (paras. 48, 85(k), 88(d), United Nations General Assembly, 2012). Serving the same purpose, yet via different means the call for education for sustainable development was highlighted. Capacity building and development of sustainability competences are crucial for the present and future generations in terms of their acting and interacting in a sustainable manner (paras. 62, 229-235, United Nations General Assembly, 2012).
