Text:
Blocks California's special pollution rule
Disapproves the rule from the Environmental Protection Agency that allowed California to set its own pollution standards for vehicles and engines. This action makes the California rule have no legal power.
What is the real world impact?

Limits state power over environmental rules
Stops California from setting its own, often stricter, pollution standards. This ensures a single, national standard for vehicle makers, which critics argue could weaken overall environmental protections.
•
Creates a single national standard for vehicle makers
Makes it easier and cheaper for car and engine companies to operate by requiring them to follow one set of federal rules instead of different rules for different states.
When does this start?
This disapproval takes effect immediately on June 12, 2025, and the EPA rule will no longer have any power.
