"Five of the states have Republican governors. The RGGI proposal follows California's vote to extend its cap-and-trade program to fight climate change."
"Nine eastern states announced Wednesday that they have agreed on a proposal to cut global-warming pollution from the region's power plants an additional 30 percent between 2020 and 2030.
The compact of Northeastern and Mid-Atlantic states known as the Regional Greenhouse Gas Initiative (RGGI) has worked for two years to hammer out the next step in their landmark emissions cap-and-trade program, which puts a price on carbon dioxide emissions from the production of electricity. The program has a track record of cutting emissions fairly painlessly across a densely populated section of the country.
Advocacy groups and policy makers have been closely watching the outcome of the negotiations. The RGGI states' decision on how to move forward, which still must be finalized, is seen as a test case of states' commitment to cut greenhouse gas emissions as the Trump administration attempts to dismantle federal climate policies, including the Clean Power Plan that was the Obama administration's plan for controlling power plant emissions."
