Summary:
The Trump administration is moving to revise the EPA’s scientific determination that greenhouse gases endanger public health – a 2009 Endangerment Finding foundational to Clean Air Act climate regulations. This unprecedented challenge targets the legal basis for vehicle emissions standards and power plant rules. If successful, the change would cripple federal authority to regulate carbon emissions, benefiting fossil fuel industries while hindering U.S. climate commitments.
What This Means for You:
- Reduced Clean Air Protections: Expect weaker emissions standards for vehicles and industrial facilities in your area
- Business Uncertainty: Energy sector companies should prepare for legal battles and policy reversals post-2020 election
- State-Level Action: Residents in CA, NY, and climate alliance states will see accelerated local emissions regulations
- Legal Challenges Ahead: This policy faces near-certain lawsuits from 23 states with existing clean air lawsuits

People Also Ask About:
- What is the EPA endangerment finding? The 2009 determination that greenhouse gases threaten public health through climate change effects.
- Why would Trump challenge this now? To create lasting barriers to climate regulation before potential administration change.
- Could this affect fuel efficiency standards? Yes, current CAFE standards for vehicles rely directly on this finding.
- How would this impact Paris Agreement goals? Removes federal authority to enforce emission reduction commitments.
Expert Opinion:
“Challenging established endangerment science sets dangerous precedent,” warns Dr. Michael Gerrard, Columbia Climate Law Director. “This isn’t just about current regulations – it aims to permanently disable EPA’s regulatory architecture for climate policy regardless of future administrations or worsening climate impacts.”
