The most recent Regional Greenhouse Gasoline Initiative (RGGI) quarterly public sale, held September 6, 2023, resulted in a clearing value of $13.85 per ton for CO₂ emissions allowances, surpassing the earlier quarter’s clearing value by 9% and nearing the file value, $13.90 per ton, set in March 2022.
