Mitigating Greenhouse Gas Emissions

Reducing greenhouse gas emissions in the Commonwealth of Massachusetts.

The Global Warming Solutions Act (GWSA) of 2008 requires a 25% reduction in greenhouse gas (GHG) emissions from all sectors of the economy below the 1990 baseline emission level in 2020 and at least an 80% reduction in 2050.

The Act Creating A Next-Generation Roadmap for Massachusetts Climate Policy, signed into law in 2021, requires at least 50% emissions reduction by 2030, at least 75% emissions reduction by 2040, and at least net zero GHG emissions by 2050, provided that in no event shall the level of emissions in 2050 be higher than a level 85% below the 1990 level.
