NEPA and Assessment of Greenhouse Gas Emissions
The growing national focus on greenhouse gas (GHG) emissions is creating new challenges for the application of one of the most venerable federal environmental laws, the National Environmental Policy Act (NEPA). NEPA requires federal agencies to analyze the environmental effects of their proposed actions in formal environmental studies. The purpose of the law is to generate better information on environmental impacts for agency decisionmakers and the public, so that agencies can make better decisions.
