In the 2012 edition of its flagship report, Worldwatch celebrates the twentieth
anniversary of the 1992 Earth Summit with a far-reaching analysis of progress
toward building sustainable economies. Written in clear language with
easy-to-read charts, State of the World 2012 offers a new perspective on what
changes and policies will be necessary to make sustainability a permanent
feature of the world's economies. The Worldwatch Institute has been named one of
the top three environmental think tanks in the world by the University of
Pennsylvania's Think Tanks and Civil Societies Program.
