The U.S. Environmental Protection Agency wants to change how it analyzes problems and makes decisions, in a way that would give it vastly expanded power to regulate businesses, communities and ecosystems in the name of “sustainable development,” the centerpiece of a global United Nations conference slated for Rio de Janeiro next June.

The major focus of the EPA thinking is a weighty study the agency commissioned last year from the National Academies of Science. Published in August, the study, entitled “Sustainability and the U.S. EPA,” cost nearly $700,000 and involved a team of a dozen outside experts and about half as many National Academies staff.
