BOSTON (WWLP) – Environmentalists are calling on Massachusetts to help keep the air clean by reducing emissions from fossil fuels like coal and gasoline.

They want Governor Charlie Baker to follow through on his promise to double the reduction rate for power plant emissions from 2.5% to 5% per year.

Pollution went down 4.8% in 2016; however, the City of Springfield had more than 30 days with elevated smog pollution in 2015. Smog buildup can aggravate respiratory conditions like asthma.

Advocates like Chloe Hedrich are looking into other power sources to help fuel the next generation. “Moving towards these renewable sources, like wind and solar, which Massachusetts has already been a leader in; but it could really prove to be a bigger leader will have a huge impact positively on the generations to come.”

State lawmakers have filed several environmental bills, including one that would transition Massachusetts to 100% renewable energy by 2050.
