The 2012 United Nations Conference on Sustainable Development (“Rio+20”) will provide “a historic opportunity to define pathways to a safer, more equitable, cleaner, greener and more prosperous world for all.” Rio+20 comes twenty years after the 1992 Earth Summit in Rio, where participating governments agreed to several historic accords to promote a more sustainable environment. Subsequent conferences followed suit with more accords aimed at improving and augmenting preceding commitments. One of the most important documents that resulted from the 1992 Earth Summit was Agenda 21, a planning-oriented framework on redefining economic growth while also promoting social equity and ensuring environmental protections.
