The Rio+20 Conference : The United Nations Conference on Sustainable Development (UNCSD) is being organized in pursuance of General Assembly Resolution 64/236 (A/RES/64/236), and will take place in Brazil on 20-22 June 2012 to mark the 20th anniversary of the 1992 United Nations Conference on Environment and Development (UNCED), in Rio de Janeiro, and the 10th anniversary of the 2002 World Summit on Sustainable Development (WSSD) in Johannesburg.

As delegates and NGOs flock to Rio for the Rio + 20 Global Environmental Summit starting on Wednesday, the world should be clear about expectations for this event. The assembly of governments, frequently represented by heads of state, and a myriad of NGOs and other organizations does not guarantee that a significant agreement will emerge about the world’s many environmental problems.

Having participated in 1992 as a member of the delegation of an international organization in both the official meeting of governments and in the Forum of Non-Governmental Organizations, I remember being impressed by the contrast between the conventional thinking inside official conference and the dynamism, passion, and innovation visible at the Forum. These were two worlds apart, in style, content, and process. And they did not meet.

Inside the conference center, government officials from both rich and poor countries did not demonstrate leadership in reforming official policies or in creating a compelling ethical platform from which change would develop. The Rio official statements are occasionally referenced 20 years later, but their impact has been minimal on national and local practice. In the Forum, the environmental movement was strengthened by the presence and energy of new members and eventually led to the World Social Forum, which started in Porto Alegre, Brazil some years later. The challenging slogan, “Another World is Possible,” which came later from the World Social Forum, had neither the tone nor the content of the Rio meeting 20 years ago.

My concerns about Rio + 20 are also based on the disappointing Copenhagen Summit on Climate Change in 2009, where the processes of the United Nations were subverted by an agreement . . .
