"WASHINGTON - A group of 21 state attorneys general, the District of Columbia, and several major U.S. cities urged the Biden administration to finalize significantly stricter vehicle emissions rules than it has proposed.

The U.S. Environmental Protection Agency (EPA) in August called for reversing the Trump-era loosening of vehicle emissions rules with a new plan to boost efficiency 10% in the 2023 model year and aim for a fleet average of 52 miles per gallon (mpg) by 2026.

But the states and cities want more stringent rules saying automakers have enough time to meet tougher rules.

"There is no need to wait to require further deployment of these technologies or to delay the massive economic and public health benefits of reducing these emissions," wrote the state attorneys general, led by California and joined by New York City, Los Angeles, San Francisco, Denver and others."
