The Environmental Protection Agency (EPA) has released MOVES6, its latest model for estimating emissions from cars, trucks, buses, and motorcycles. State and local air quality and transportation agencies outside California can use it now for air quality plans. It becomes required for new transportation conformity analyses on October 27, 2028, after a two-year grace period that starts October 27, 2026. EPA says it updated the model for changes in federal vehicle rules, laws, and data, including lower electric vehicle projections.
