An Act to reduce greenhouse gas emissions threatening our natural environment

This bill amends Massachusetts law to require the state secretary to create market-based rules that reduce greenhouse gas emissions across transportation, commercial, industrial, and residential sectors. The regulations must prioritize lowering emissions from passenger vehicles and light trucks while ensuring low-income households are not disproportionately affected and identifying businesses at risk of negative economic impacts. Additionally, the bill mandates that the secretary publish a comprehensive energy plan by September 2025 and every five years thereafter, which must outline strategies for meeting future energy demands through conservation and efficiency. These rules allow the state to join existing regional or national carbon markets and require the secretary to review and adjust the compliance mechanisms at least once every 30 months.
