Acadia Center, a Northeast-based environmental advocacy group that was among critics of the natural gas emphasis in the 2013 CES, discovered a math error in DEEP’s calculation of greenhouse gas emissions in 2013.

Instead of being at, or even just below, the 2020 emissions cap dictated by the state’s Global Warming Solutions Act – which is where emissions were in 2012 they were heading back up. DEEP has since revised its calculation.

Acadia’s calculation, based on publicly available data, showed more. “We found an increase of 7.5 percent from 2012 to 2015,” said Bill Dornbos, who heads Acadia’s Connecticut office. “Looking at the data that’s out there now for 2016, we’re pretty confident 2016 will be higher than 2015 and maybe even significantly so.”

Most believe the cause is not the electricity sector, which has all but eliminated its dirtiest generators in the state and region. Rather the lower price of gasoline has increased the use of vehicles and the purchase of less fuel-efficient ones. Transportation accounts for about 40 percent of emissions.

Emissions from buildings and manufacturing account for another 40 percent, and that’s gone up too. “Our current natural gas emission level is higher than the entire carbon budget for 2050 (80 percent below 2001 emissions),” Dornbos said.
