Baker tackles state’s strict greenhouse emissions rules

Gov. Charlie Baker’s administration has released a set of new rules aimed at bringing Massachusetts into full compliance with an ambitious state law that calls for a 25 percent reduction in greenhouse gas emissions by the end of the decade.

The regulations announced yesterday include clean energy requirements for utilities, reductions in carbon dioxide emissions from electricity generating plants, and curbs on methane emissions from natural gas distribution systems. Officials also planned to announce a “lead by example” provision that establishes new fuel efficiency standards for the state’s own fleet of passenger vehicles.

The new regulations take effect on Jan. 1.

The state launched a review and held public hearings following a May 2016 ruling by the state’s highest court. The justices sided with environmental groups that sued Massachusetts, saying it wasn’t doing enough to meet greenhouse gas limits called for in the 2008 Global Warming Solutions Act.

In addition to the 2020 target of a 25 percent reduction in emissions relative to 1990 levels, the law sets an 80 percent reduction goal by 2050.

In a statement, Baker said “combatting and preparing for the impact of climate change remains a top priority of our administration, and requires collaboration across state government and with stakeholders throughout Massachusetts.”

According to Secretary of Energy and Environmental Affairs Matthew Beaton, the Bay State was already closing in on the 2020 goal, having achieved a 21.3 percent reduction in emissions, so far.

“We are trending in a very good direction,” he said, “and we are confident that we are going to hit those goals.”

The state is soliciting bids under a separate law passed last year for renewable energy projects that will generate 1,600 megawatts of power from offshore wind facilities and 1,200 megawatts from hydropower, solar and onshore wind over the next 10 years.
