International recognition of ESD as the key enabler for sustainable development is growing steadily. The role of ESD was recognized in three major UN summits on sustainable development: the 1992 UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil; the 2002 World Summit on Sustainable Development (WSSD) in Johannesburg, South Africa; and the 2012 UN Conference on Sustainable Development (UNCSD) in Rio de Janeiro. Other key global agreements such as the Paris Agreement (Article 12) also recognize the importance of ESD. Today, ESD is arguably at the heart of the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs) (United Nations, 2015). The SDGs recognize that all countries must stimulate action in the following key areas – people, planet, prosperity, peace and partnership – to tackle the global challenges that are crucial for the survival of humanity. Some of these SDGs include ensuring affordable and clean energy, providing clean water and sanitation, and partnership for these goals. ESD is explicitly mentioned in Target 4.7 of SDG4, which aims to ensure that all learners acquire the knowledge and skills needed to promote sustainable development and is understood as an important means to achieve all the other 16 SDGs (UNESCO, 2017). Additionally, SDG17 focuses on strengthening the means of implementation and revitalization of global partnership for sustainable development.
