Massachusetts Governor Charlie Baker signed into law late last week one of the nation’s most sweeping climate bills, putting the state on a path to net zero carbon emissions by 2050.
The law sets emissions limits of 50% below 1990 levels by 2030 and 75% cuts by 2040 with interim limits every five years. To achieve those goals, the Bay State will add gigawatts of offshore wind power, spur cities and towns to adopt a net-zero building code, and set targets for electric vehicles, charging stations, and energy storage.
The state expects that it will be able to fully eliminate 85% of all carbon emissions by 2050. For the remaining, 15%, it will have to find other options, including tree planting or direct air capture of carbon dioxide. The net-zero target of 2050 is encouraged by the Intergovernmental Panel on Climate Change to avoid warming of greater than 1.5˚ C.
