An Act relative to the clean heat standard

This bill establishes Massachusetts' Clean Heat Standard, requiring natural gas utilities and other heating fuel sellers (like oil or propane providers) to reduce emissions from the state's heating sector. Obligated parties must retire "clean heat credits" earned from qualifying energy-efficient upgrades (e.g., heat pumps or insulation) to meet annual targets, with 20% of required credits specifically sourced from low-income households and 20% from moderate-income households. The Massachusetts Department of Environmental Protection will oversee the credit system, track compliance, and ensure equity by prioritizing access for households with high energy costs. The program aims to align with state climate goals while mandating that utilities directly support vulnerable communities through clean heating solutions.
