Overview

• The draft rule, transmitted to the White House Office of Management and Budget on June 30, seeks to rescind the EPA’s 2009 endangerment finding that established greenhouse gases as a public health threat.
• It would also eliminate federal tailpipe emissions standards designed to drive automakers toward electric vehicles.
• The proposal argues that the EPA exceeded its authority under the Clean Air Act rather than challenging the science of climate change.
• Once interagency review is complete and the Administrator signs off, the draft will be published in the Federal Register for a public notice-and-comment period.
• Legal experts say challenges are likely and caution that repealing the finding would undercut federal tools for limiting emissions from power plants, vehicles, and industry.
