1 week agoUS: Trump's EPA sued by environmentalist, health groups
The 2009 "endangerment finding" came about as a result of a prolonged legal battle that ended in a 2007 Supreme Court ruling, Massachusetts v. EPA, where it was determined that greenhouse gases qualify as pollutants under the Clean Air Act.
