Carbon prices are way down, thanks to the Supreme Court’s hold on Clean Power Plan

“Low RGGI prices hamper the region’s ability to pursue additional carbon cuts,” and make clean energy investment less profitable, said Jordan Stutt, a clean energy analyst for the Acadia Center, a New England climate policy think tank.

He said lower prices mean states earn less money from trading carbon, reducing the amount of auction money they will get that can be reinvested in state-run clean energy and energy efficiency programs.
