An Act aligning the commonwealth's transportation plans with its mandates and goals for reducing emissions and vehicle miles traveled

Massachusetts bill SD 1327 requires transportation agencies to align regional and statewide transportation plans with the state's emissions and vehicle miles traveled (VMT) reduction goals. It mandates that all transportation plans include 20-year emissions and VMT impact assessments, and that projects must incorporate localized "mitigation measures" (like transit expansions, active transportation infrastructure, or land-use changes) prioritized for communities directly affected by the project. The bill directly affects metropolitan planning organizations and state transportation agencies, requiring them to demonstrate compliance with existing emissions sublimits and VMT reduction targets set under Chapter 21N. These targets, established by the Secretary of Transportation, must be integrated into all transportation planning documents and public hearings.
