Building upon the framework in the Massachusetts 2050 Decarbonization Roadmap Report, the Massachusetts Executive Office of Energy and Environmental Affairs (EEA) and Massachusetts Department of Energy Resources (DOER) must adopt a statewide greenhouse gas (GHG) emissions limit that achieves net zero statewide GHG emissions by 2050, or at least 85% below the 1990 level. By 2025, and every five years thereafter until 2050, EEA and DOER must set interim statewide GHG emissions limit, accompanied by a roadmap to achieve that limit. (Reference Senate Bill 9, 2021, and Massachusetts General Laws Chapter 21N, Section 3)
