United Nations Conference on Sustainable Development

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 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 ten-day mega-summit, which culminated in a three-day high-level UN conference, was organized by the United Nations Department of Economic and Social Affairs and included participation from 192 UN member states – including 57 head of state and 31 head of government,^{[citation needed]} private sector companies, NGOs and other groups. The decision to hold the conference was made by UN General Assembly Resolution A/RES/64/236 on 24 December 2009. It was intended to be a high-level conference, including heads of state and government or other representatives and resulting in a focused political document designed to shape global environmental policy.

During the final three days of the Conference, from 20 to 22 June 2012, world leaders and representatives met for intense meetings which culminated in finalizing the non-binding document, "The Future We Want", which opens with: "We the Heads of State and Government and high-level representatives, having met at Rio de Janeiro, Brazil, from 20 to 22 June 2012, with the full participation of civil society, renew our commitment to sustainable development and to ensuring the promotion of an economically, socially and environmentally sustainable future for our planet and for present and future generations."

In 1992, the first conference of its kind, the United Nations Conference on Environment and Development (UNCED), commonly referred to as the Rio Conference or Earth Summit, succeeded in raising public awareness of the need to integrate environment and development. The conference drew 109 heads of state to Rio de Janeiro, Brazil, to address what were dubbed urgent problems of environmental protection and socio-economic development. The Earth Summit influenced subsequent UN conferences, including Rio+20 and set the global green agenda. "The World Conference on Human Rights, for example, focused on the right of people to a healthy environment and the right to development; controversial demands that had met with resistance from some Member States until the Earth Summit."

Major outcomes of the conference include the United Nations Framework Convention on Climate Change (UNFCCC) – a climate-change agreement that led to the Kyoto Protocol, Agenda 21, the United Nations Convention on Biological Diversity (CBD) and the United Nations Convention to Combat Desertification (UNCCD). It also created new international institutions, among them the Commission on Sustainable Development, tasked with the follow-up to the Rio Conference and led to the reform of the Global Environment Facility.

Ten years later, Earth Summit 2002, informally nicknamed Rio+10, was held in Johannesburg, South Africa, with the goal of again bringing together leaders from government, business and NGOs to agree on a range of measures toward similar goals. At Rio+10, sustainable development was recognized as an overarching goal for institutions at the national, regional and international levels. There, the need to enhance the integration of sustainable development in the activities of all relevant United Nations agencies, programs and funds was highlighted. The discussion also encompassed the role of institutions in stepping up efforts to bridge the gap between the international financial institutions and the multilateral development banks and the rest of the UN system.

Major outcomes of that conference include the Johannesburg Declaration and almost 300 international partnership initiatives meant to help achieve the Millennium Development Goals.

The conference had three objectives – to secure renewed political commitment for sustainable development, to assess the progress and implementation gaps in meeting previous commitments, and to address new and emerging challenges.
