An Act aligning the Commonwealth's transportation plans with its climate goals

This bill requires Massachusetts transportation planning to align with climate goals by mandating that regional transportation plans and projects meet greenhouse gas emissions and vehicle miles traveled (VMT) reduction targets. It establishes a process for assessing emissions and VMT impacts of transportation projects, including requiring mitigation measures like transit expansions, active transportation infrastructure, or land-use changes to offset emissions. The Department of Transportation must publish these assessments online and ensure mitigation efforts are localized to affected communities or underserved areas. The bill directly affects metropolitan planning organizations, state agencies, and project developers by making compliance with emissions and VMT targets a condition for approving transportation plans and projects.
