BOSTON — The Latest on rules governing greenhouse gas emissions (all times local):

3:31 p.m.

Gov. Charlie Baker’s administration has released new rules for greenhouse gas emissions.

The regulations announced Friday are aimed at bringing Massachusetts into compliance with an ambitious state law that calls for a 25 percent reduction in emissions by the end of the decade.

The regulations — which kick in Jan. 1, 2018 — 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.

The state also plans to curb emissions from its own fleet of vehicles.

The rules were drawn up in response to a ruling in a lawsuit brought by environmental advocates.

State officials say the rules likely will increase consumer electric bills, but by no more than 2 percent a year.
