Blocks California from setting its own greenhouse gas emission standards for new cars

This bill would block California from setting its own greenhouse gas emission standards for new cars. If passed, a 2009 rule from the Environmental Protection Agency (EPA) that allowed California to have stricter standards would be canceled. This means new vehicles sold in California would need to meet federal emission standards instead.

What Would Change

Currently, the Environmental Protection Agency's 2009 rule allows California to enforce its own greenhouse gas emission standards for new cars from 2009 models onward. If this bill becomes law, that EPA rule would be canceled, and California would have to follow federal emission standards for new motor vehicles.

Key Provisions

Blocks the Environmental Protection Agency's 2009 rule that allowed California to set its own greenhouse gas emission standards for new motor vehicles.
Removes California's ability to enforce its own greenhouse gas emission standards for new cars from 2009 models onward.
Ensures that the federal government's emission standards would apply to new motor vehicles in California.
