Proposed Massachusetts air regulations target 80% decarbonization by 2050
Massachusetts Gov. Charlie Baker (R)'s Department of Environmental Protection has issued a draft of new clean air regulations to address greenhouse gas emissions, seven months after the state's Supreme Court ruled it was not doing enough to cut them.
Under the proposal, utilities would be required to purchase generation credits from zero-carbon sources, starting at 16% in 2018 and increasing to 80% by 2050. Renewables, nuclear and fossil generation with carbon capture would be eligible for the Clean Energy Credits.
The Massachusetts Global Warming Solutions Act requires the state reduce greenhouse gas emissions 80% from 1990 levels by 2050. Separate regulatory programs announced last week target emissions from vehicles and fossil fuel extraction and transport, along with the power sector rules.
