An Act to reduce greenhouse gas emissions by permitting local option all-electric buildings and homes ordinances

This bill amends state law to allow Massachusetts towns and cities to pass local ordinances requiring new buildings and major renovations to be all-electric, meaning they cannot use natural gas, heating oil, or propane for heating, cooling, or cooking. The legislation defines "all-electric" as systems that rely on electricity or geothermal energy for these purposes while excluding fossil fuel infrastructure, with specific exceptions for vehicle fueling, mechanic shops, and emergency backup power. By giving municipalities the authority to mandate these standards, the bill aims to reduce greenhouse gas emissions by shifting energy use away from fossil fuels in residential, commercial, and public structures. The rules apply to construction projects and major renovations where building permit applications are submitted on or after January 1, 2022.
