The United Nations Conference on Sustainable Development (UNCSD), also known as Rio 2012, Rio+20 (Portuguese pronunciation: [ˈʁi.u ˈmajʒ ˈvĩtʃi]), or Earth Summit 2012 was the third international conference on sustainable development aimed at reconciling the economic and environmental goals of the global community. Hosted by Brazil in Rio de Janeiro from 13 to 22 June 2012, Rio+20 was a 20-year follow-up to the 1992 Earth Summit / United Nations Conference on Environment and Development (UNCED) held in the same city, and the 10th anniversary of the 2002 World Summit on Sustainable Development (WSSD) in Johannesburg.
The primary result of the conference was the nonbinding document, "The Future We Want," a 49-page work paper.[8] In it, the heads of state of the 192 governments in attendance renewed their political commitment to sustainable development and declared their commitment to the promotion of a sustainable future. The document largely reaffirms previous action plans like Agenda.
