History

Historical Context

The Clean Air Act amendments of 2009 marked a significant step in U.S. environmental policy, as the EPA determined greenhouse gases endanger public health. This decision followed the 2007 Supreme Court ruling in Massachusetts v. EPA, which affirmed the EPA's authority to regulate such emissions. The current lawsuit against the EPA's repeal of the endangerment finding reflects ongoing tensions between environmental regulation and industry interests, impacting future climate policy.
