Preserving Choice in Vehicle Purchases Act of 2023

S 2090, the *Preserving Choice in Vehicle Purchases Act of 2023*, modifies federal clean air rules to restrict state vehicle emission standards. It adds a new requirement that state rules cannot "directly or indirectly limit the sale or use of new gas-powered cars," effectively blocking states from enforcing policies that would phase out internal combustion engine vehicles. The bill also mandates the EPA to cancel existing state emission waivers (like California’s) if those waivers don’t meet this new standard. This directly affects states with their own vehicle emission rules and the EPA’s authority to approve them under the Clean Air Act.
