The transportation sector is responsible for 42 percent of greenhouse gas emissions in New Hampshire. While emissions from the electric sector have declined over time, transportation emissions have remained relatively stable, and are by far the largest contributor to state emissions. While New Hampshire is a member of the Transportation and Climate Initiative, the state has yet to join its peers in committing to develop a regional clean transportation plan, nor is it a member of the Zero Emissions Vehicle (ZEV) program. While the state Senate recently advanced efforts to allow the state Department of Transportation to tap into federal funds to complete a study of the Capitol Corridor commuter rail project from Boston to Manchester, and the legislature established a commission to make recommendations on how to expand electric vehicle infrastructure in the state, New Hampshire is lacking sufficient revenue and commitment to adequately address this sector.
