The EPA in April proposed requiring a 56% reduction in projected fleet average emissions over 2026 model year requirements.

Under the initial EPA proposal, automakers are forecast to produce 60% EVs by 2030 and 67% by 2032 to meet requirements. A group representing major automakers has called the EPA plan "neither reasonable nor achievable." The EPA plans to finalize its new emissions rules by March.
