The United Nations Conference on Sustainable Development, also known as Rio +20, is scheduled from June 20 to June 22, 2012 in Rio de Janeiro, Brazil.
92 world leaders are expected to attend the conference in the Brazilian megalopolis. The name for the conference, "Rio +20," was inspired by the renowned 1992 Rio Conference, which launched the concept of sustainable development.
The People's Summit for Social and Environmental Justice is planning an alternative conference to Rio +20. The People's Summit hopes their conference will provide a forum for reflection on Rio +20's objectives and for promoting the advancement of more sustainable development, without capitalist influence.
In spite of Rio +20's hope for productive discussion during the conference, the absence of major world leaders will remain a challenge to forming a united agenda. Among the world leaders who will be absent from the Rio +20 discussions are U.S. President Barack Obama, who will be represented on the last day of the conference by Secretary of State Hillary Clinton, as well as British Prime Minister David Cameron, German Chancellor Angela Merkel and Russian president Vladimir Putin.
