- Reducing GHG Emissions from Plastics Combustion
- Since 2009, the Commonwealth has funded grants totaling more than $3 million for encouraging, expanding, and improving municipal recycling programs. Depending on composition, each ton of material recycled could abate as much as three tons of GHG emissions. Recycling also keeps money in our local economy by reducing our dependence on imported materials.
- Reducing Emissions from the Natural Gas
- Continuing an ongoing program dating back to before 1990, stopping methane leaks from natural gas distribution networks has reduced GHG emissions by 38% since 2010 and saved natural gas ratepayers money by reducing waste.
- Reducing SF6 Emissions from Gas-Insulated Switchgear
- In 2015, the three largest utilities in the state all reported SF6 emissions well below that year’s cap. However, there is work to be done to reach the 2020 goal. Although only emitted in trace amounts, SF6 is an incredibly powerful greenhouse gas, pound for pound—24 thousand times more powerful than CO2—so small amounts matter a great deal.
MassDEP is reviewing the final EPA regulations signed on September 26, 2016. These regulations extend federal Clean Air Act requirements to non-ozone-depleting substitute refrigerants. MassDEP is also reviewing the recent extension of the international Montreal Protocol framework to address refrigerants.
