Nine Mid-Atlantic and New England states have agreed to cut power plant greenhouse gas emissions across the region by 65 percent by 2030 through the nation's first cap-and-trade program to reduce carbon contributing to global climate change.New York Gov. Andrew Cuomo announced Wednesday that states in the Regional Greenhouse Gas Initiative have agreed to reduce the cap on power plant carbon emissions an additional 30 percent below 2020 levels by 2030. The Democrat said the new cap will be 65 percent below the program's 2009 starting level.The initiative caps carbon dioxide emissions and trades the excess in auctions, which have generated $2.7 billion in proceeds used by the states for clean energy programs."The Regional Greenhouse Gas Initiative has been an incredible success in reducing greenhouse gas emissions that contribute to global climate change in New York and the Northeast, while supporting thousands of jobs and billions of dollars of investments in sustainable development projects," said Basil Seggos, New York's environmental commissioner.
