What the Advanced Clean Truck Rule Will Do for Massachusetts

The adoption of the ACT and HDO rules in Massachusetts is projected to significantly reduce toxic air pollutants and carbon emissions from medium- and heavy-duty vehicles, leading to substantial health savings and net societal benefits by 2050.

• Medium- and heavy-duty (M/HD) vehicles in Massachusetts represent less than 10% of all vehicles but contribute disproportionately to pollution, accounting for approximately 46% of NOx, over 40% of fine particulate matter (PM2.5), and around 9% of the state's global warming pollution.
• Adopting the ACT rule is expected to increase the share of zero-emissions M/HD vehicle sales in Massachusetts from less than 1% today to nearly 30% by 2030 and nearly 60% by 2035, which would eliminate almost 22 million metric tons of cumulative carbon dioxide through 2050.
• The implementation of ACT and HDO regulations is projected to reduce NOx emissions from M/HD vehicles by nearly 85% and PM2.5 emissions by 27% by 2050, resulting in 152 avoided premature deaths, 157 avoided hospital visits, and nearly 90,000 avoided minor sicknesses.
• The transition to clean trucks is estimated to generate $1.7 billion to $1.8 billion in health-related savings and $7.5 billion in cumulative net societal benefits by 2050, with annual net societal benefits reaching $837 million.
• Electric truck operators are projected to see more than $12,000 in net lifetime savings per vehicle by 2040 due to falling battery costs and reduced fuel and maintenance expenses.
