I recently updated the Primer on the Emergence and Evolution of Sustainable Development (1951 to 2012), to include a discussion of the United Nations Conference on Sustainable Development (known as Rio+20), held in Rio de Janeiro, Brazil, June 20-22, 2012. The updated text takes a close look at the idea of the green economy, which was endorsed by delegates at the conference as a flexible mechanism for advancing sustainability.
