International recognition of sustainable development as a key element is growing steadily. Its role 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 are the Paris Agreement and the 2030 Agenda for Sustainable Development (United Nations, 2015). The SDGs recognize that all countries must stimulate action in the following key areas – people, planet, prosperity, peace and partnership – in order to tackle the global challenges that are crucial for the survival of humanity.
