The U.S. EPA has proposed to revoke its 2009 GHG Endangerment Finding, which underpins the regulation of tailpipe (GHG) emissions from cars and trucks.
Analysis of millions of remote sensing measurements of vehicle tailpipes shows that particulate emissions from U.S. cars are still at 2005 levels, despite the availability of technology which has been used in Europe and China.
Each year, millions of people die prematurely because of exposure to fine particles emitted as a result of fossil fuel combustion. Europe and China have taken steps to address particulates from passenger cars. Upcoming US regulations provide an opportunity to catch up.
