In 2010, the U.S. Environmental Protection Agency and the Department of Transportation announced the first-ever national limits on greenhouse gas pollution from cars and light trucks. Dubbed the “Clean Cars Rule,” it would increase vehicle fuel efficiency and reduce greenhouse gas emissions by motor vehicles, a major source of carbon pollution in the U.S.
Since then, the auto industry has thrived, achieving record sales, while drivers saved $90 billion in fuel costs.
Despite these gains, the Trump administration illegally rolled back the clean car and fuel economy standards, issuing a rule based on massive technical and economic errors — and that failed to meet core legal requirements. Separately, the administration attempted to block states’ authority to protect their residents from tailpipe pollution under the Clean Air Act.
