An Act to expand carbon pricing in the commonwealth

This bill expands Massachusetts' carbon pricing system by requiring state officials to implement market-based fees or charges on specific sectors to meet greenhouse gas emission goals. The plan introduces a phased approach, starting with commercial, institutional, and industrial buildings by 2026, followed by industrial processes in 2027, the transportation sector in 2028, and finally residential heating and cooling in 2029. These fees are designed to cost at least $50 per ton of carbon emissions initially, increasing by $10 annually up to a maximum of $200 per ton, while also aiming to protect low-income communities and prevent pollution from other contaminants. Revenue generated from transportation-related fees will be distributed as rebates to residents and employers or added to the state's transportation fund.
