An Act To Update The Regional Greenhouse Gas Initiative Allowances

LD 2037 updates Maine's annual carbon dioxide emissions limits under the Regional Greenhouse Gas Initiative (RGGI) for 2027-2037, setting specific caps that decline from 2,065,595 tons in 2027 to 221,314 tons by 2037. The bill removes Maine's ability to withdraw from RGGI by repealing related provisions, ensuring continued state participation in the regional program. These changes directly affect power plants and large industrial facilities in Maine that must comply with the state's emissions cap under RGGI. The policy establishes a fixed annual reduction schedule without new regulatory mechanisms beyond the updated caps.
