Overall, RGGI has led to nearly $450 million in clean energy investments that resulted in more than $1 billion in energy savings and $2.6 billion in economic growth in the region, the report said. These results have so far helped the market survive GOP-led attacks in other states.
Last month, Delaware and Maine lawmakers reaffirmed their states' participation in RGGI after attempts by some Republicans to leave the scheme.
In New Hampshire, the Senate has sent a bill to Democratic Gov. John Lynch that would remove the state from RGGI. Catherine Corkery, director of the state's chapter, said that while the governor is ready to veto the bill, it could be in limbo until August or beyond due to the summer recess.
