A recent report from the Regional Greenhouse Gas Initiative, of which Connecticut is a member state, said the program has reduced annual average carbon dioxide emissions from electric generation sources by nearly 36 percent compared to the 2006 to 2008 time period.
That reduction amounts to 49.3 million short tons of CO2, according to the Aug. 12 report.
RGGI, launched in 2008, currently has nine member states. The program has created a cap-and-trade program for pollution permits, incentivizing cleaner generation technologies.
There are ongoing discussions about how to update caps and requirements before the end of the decade.
Some member states feel the proposals may be too stringent, and Maryland has said it may be forced to pull out if caps become too strict, the Boston Globe reported Sunday.
