The Regional Greenhouse Gas Initiative

With over a decade of proven success, RGGI reduces emissions from the power sector, creates jobs and helps pave the way to a net zero carbon future

The Regional Greenhouse Gas Initiative (RGGI) is a successful cap-and-trade carbon pricing program for the power sector. Over the last decade, participating states have seen a range of benefits while emissions and electricity costs have decreased, according to the Center for Climate and Energy Solutions. 


Established in 2009, RGGI limits carbon emissions from power plants1 by placing a regional cap on emissions and then requiring companies to buy or trade allowances to emit up to the limit of the cap. The cap decreases annually, so the allowance price rises every year. This system allows industry flexibility to meet reduction targets at the lowest possible cost. 


Independent studies of the program show RGGI works for people, business and the planet. RGGI states also outpaced power sector emissions reductions in the rest of the country by 90 percent.*


bp publicly advocated for Virginia to join RGGI and was thrilled when the governor signed that bill into law in 2020. Now bp is actively encouraging Pennsylvania to benefit from the program along with its neighbors in:

  • Connecticut
  • Delaware
  • Maine
  • Maryland
  • Massachusetts
  • New Jersey
  • New Hampshire
  • New York
  • Rhode Island
  • Vermont
  • Virginia


We’re also part of a coalition of businesses and environmental organizations in Pennsylvania working to bring this policy to the Keystone State. We believe it’s good for citizens, the environment and the economy.
