Is it time to rethink the Northeast’s cap-and-trade system?

MAINE MORNING STAR • September 18, 2026

Twenty years ago, a group of Northeastern states signed on to a plan to reduce the greenhouse gases spewing from power plants by making generators pay for the carbon they release. Since then, the region’s power sector emissions have dropped by half, and states have reaped more than $10 billion in revenue to invest in energy programs. The Regional Greenhouse Gas Initiative, or RGGI, looks like a success. Two decades in, however, the price power plants pay for each ton of carbon emissions is more than 12 times what it was at the beginning, clean energy development in the region faces daunting challenges, and emissions have started creeping back up. A growing chorus of voices is now questioning whether RGGI is still worth the investment at a time when soaring power prices are straining household budgets.
