Environmental Protection Agency officials might end the agency's prior "endangerment finding" for greenhouse gas emissions and repeal vehicle regulations.

The Trump administration’s latest and greatest assault on climate change mitigation would eliminate all greenhouse gas emissions regulations for motor vehicles and engines.

The so-called endangerment finding that the EPA proposed revoking on Tuesday forms the legal basis for the government’s authority to impose limits on certain emissions, which scientists say are responsible for climate change and health issues such as breathing problems.
