What is RGGI?

RGGI is a market-driven, cap-and-invest program to reduce carbon dioxide emissions from power plants and uses the money generated to reduce air pollution, improve energy efficiency, provide for fossil fuel worker transitions, and work toward environmental justice, and more.

Support Regional Greenhouse Gas Initiative

Pennsylvania has joined 11 other states in the Regional Greenhouse Gas Initiative (RGGI).

The Regional Greenhouse Gas Initiative (RGGI) is a cap and invest market driven approach to reducing carbon emissions. It works by imposing a fee on power plants to penalize carbon pollution and then using that money accrued by individual states to pay for state climate change reduction efforts. RGGI has a more than 10-year proven track record of reducing CO2 emissions and significantly improving the lives of the people in its member states. RGGI will benefit all Pennsylvanians by improving the air quality and therefore our health, reducing the effects of climate change that we currently already struggle to grapple with, and bringing 21st century jobs to our Commonwealth.


RGGI is currently under legal threat from lawsuits from the fossil-fuel lobby. Please spread the word about the benefits of RGGI by writing to your state legislators and submitting letters to the editor to your local papers.

Pennsylvania's Path to RGGI


July 27, 2022

Unfortunately the judge has reinstated the injunction against PA participating in the next RGGI auction. Hopefully this is just the next iteration of the ball going back and forth and not where the ball lands until the lawsuits are decided, which won't be until much later this year or possibly the beginning of next year.,

July 20, 2022

On July 8th, the PA Commonwealth Court imposed an injunction on RGGI, preventing Pennsylvania from participating in the quarterly RGGI auctions until all legal matters are resolved. However, the DEP appealed the injunction, which again allows Pennsylvania to participate in the September 2022 auction.  This could, however, change back again. With the recent actions limiting federal powers to combat climate change, it is more important than ever that action is taken at the state level.


May 17, 2022

Right now we don't know if the PA Senate will vote on the anti-RGGI Bill HB 637, or modify it to reflect the fact that PA has entered RGGI.


The RGGI opponents are still fighting RGGI with lawsuits.


We need your help in spreading the word about the benefits of RGGI by calling your state legislators and writing Letters to the Editor.


April 7, 2022

The Pennsylvania State House of Representatives and PA Senate are back in session. 


In the next few weeks, the PA Senate will be voting on an amended bill called HB 637 (it recently passed the PA House and is now in the Senate). The anti-RGGI HB 637 bill, recently renamed The Energy Sustainability and Investment Act), not only would place restrictions on the regulation of carbon dioxide, but also would end Pennsylvania’s current attempt to join RGGI and replace it with a one-time infusion of $250 million from Covid Relief funds to pay for only some environmental actions–not the broad scope of benefits that RGGI would enable. Compared to RGGI, HB 637 will keep us dependent on fossil fuels and accelerate climate change, especially here in PA. In the RGGI program, the source of the money comes from the fossil fueled-fired power plants, incentivizing them to reduce their carbon emissions. Moreover, PA’s RGGI program would bring around $400 million each year to our state–nearly twice as much as the one-time infusion proposed in HB 637—annual RGGI revenue that would go towards reducing the leading contributor to climate change (carbon dioxide pollution from fossil fueled-fired power plants) and towards climate adaptation and mitigation strategies, and more. 

Soon the PA General Assembly will be voting on SB 119, a bill that would severely curtail PA's current attempt to join RGGI.


On April 4, 2022, the PA Senate failed to meet the 2/3 majority needed to override Governor Wolf's veto of the RGGI disapproval resolution.  In other words, the PA Senate failed to stop Pennsylvania from entering RGGI.  The RGGI rule was poised to be published within the week. However, on April 5 the Commonwealth Court put a pause on Pennsylvania joining RGGI—putting Pennsylvania's attempt to become the 12th member state of RGGI on hold. That pause expired, and on April 23, Pennsylvania entered RGGI.
