On August 2, 2016, the White House Council on Environmental Quality (CEQ) issued its final guidance for federal agencies to assess the impact of their decisions on greenhouse gas emissions (GHGs) and also how such decisions may be impacted by a changing climate (e.g., future sea level rise impacts on a long-term infrastructure project proposed for a coastal barrier island) when conducting reviews under the National Environmental Policy Act (NEPA). The final guidance follows CEQ’s issuance of draft guidance in 2010 and revised draft guidance in 2014, incorporating consideration of public comments and feedback on the two drafts. Following this six-year process, CEQ’s guidance is a recommendation to federal agencies versus a formal legal requirement and therefore does not have the same authority as a federal rule or regulation.
The guidance does not establish any particular quantity of GHG emissions as representing a significant burden on the environment – that determination will be left to the discretion of the agencies. However, the guidance does prohibit the so-called “de minimis approach” where an agency would compare a Federal action’s GHG emissions to global GHG emissions, finding that since the action did not represent a meaningful percentage of the global GHG inventory, the action did not significantly affect the environment.
