An act relating to revoking Vermont’s use of California’s Clean Air Act waiver

This bill (S 101) prohibits Vermont from adopting California’s stricter vehicle emission standards under the Clean Air Act. It amends Vermont law to explicitly ban the use of California’s waiver for new motor vehicle emissions rules, requiring the state to follow federal baseline standards instead. The bill repeals Vermont’s existing Low Emission Vehicle and Zero Emission Vehicle Rules and updates climate planning requirements to exclude California standards. It directly affects auto manufacturers selling in Vermont and Vermont’s environmental regulations, taking effect July 1, 2025.
