The Trump administration has officially revoked the 2009 endangerment finding, a pillar of U.S. climate policy. This EPA determination recognized greenhouse gases as a threat to public health, allowing their regulation under the Clean Air Act. Its elimination leaves emission standards for vehicles, power plants, and industry without a legal basis, a move that is already generating promises of lawsuits.
Impact on technical regulations and engine development ⚙️
The revocation directly affects technical standards such as vehicle efficiency standards (CAFE) and emission limits for power plants. Without the legal foundation of the endangerment finding, these regulations lose their key support. This could slow regulatory pressure to innovate in cleaner combustion engines or accelerate electrification, giving more leeway to conventional technologies based on fossil fuels in the short term.
A new air for the same old air 💨
It seems the strategy is to combat climate change by eliminating the paper that mentions it. It's a direct approach: if you can't reduce emissions, you reduce the regulation that measures them. Thus, manufacturers can breathe a sigh of relief, while some citizens might notice another type of relief when breathing. A move that will undoubtedly leave a mark... though not precisely one of reduced carbon.
