Congress blocks California's clean truck rules

What it does

Congress used a special law to cancel an EPA rule. The rule let California set its own air rules for big trucks and buses. The rule was finalized in April 2023. It is now void. States that follow California's rules also lose that power.

Who it affects

People in California and 10 other states lose cleaner air from trucks and buses. Truck and bus makers pay less to follow air rules. Communities near ports, warehouses, and transit hubs lose better air.

One thing to notice

The rule gave California permission to set stricter air rules than the nation's rules allow. Canceling it removes that permission and blocks 10 other states too.
