EPA Administrator Recommends to White House to Abandon the GHG Endangerment Finding
In this previous article, we have summarized the high-level changes announced by the White House, EPA and other related agencies and their potential impact on the transport sector, with an emphasis on decarbonization / emissions abatement.
This is a very brief alert on perhaps the most important topic: the greenhouse gas (GHG) endangerment finding.
Background
President Trump’s Jan 20th Executive Order directs the Administrator of the EPA to “submit joint recommendations to the Director of OMB on the legality and continuing applicability” of the GHG Endangerment findings previously published following the Supreme Court’s landmark 2007 ruling in Massachusetts v. EPA. The endangerment finding provides EPA with the legal basis for setting GHG-limiting standards for vehicles, power plants and other sources.
According to the Washington Post, the EPA Administrator Lee Zeldin has recommended to the White House that the endangerment finding be scrapped. If enacted upon, this will face a very high legal bar in courts.
