The White House announced it will revoke an important finding: greenhouse gases harm public health.
This finding has supported the U.S. since 2009 in using the Clean Air Act to regulate emissions from cars, power plants, and large factories.
If revoked now, the federal government will find it harder to require reductions in carbon dioxide.
Car companies may slow down the development of electric vehicles, but places like California still have their own stricter rules, so regulations may vary across the U.S.
For power generation, coal plants may get 'relief,' but coal must still face the reality of cheaper natural gas, solar, and wind energy.
Increased emissions will worsen global warming, and coal power also produces pollutants like fine particles, sulfur dioxide, and mercury, which affect respiratory and heart health.
This decision may also trigger new lawsuits and leave the U.S. without leadership in international climate cooperation.
The bigger issue is: when the government no longer respects scientific evidence, policies become inconsistent, and long-term environmental protection efforts become harder to maintain.
