The most recent Regional Greenhouse Gas Initiative (RGGI) quarterly auction, held on March 3, 2021, resulted in a clearing price of $7.60 per short ton of carbon dioxide (CO2), surpassing the previous high price of $7.50 per short ton reached in December 2015. States can reinvest the proceeds from these auctions in consumer benefit programs to improve energy efficiency and accelerate the deployment of renewable energy technologies in the electric power sector.
