The "Greenhouse Gas Pollution Superfund Act" establishes a cost-recovery program in Minnesota aimed at addressing greenhouse gas emissions. It creates a dedicated account for payments from responsible parties, which will fund climate change adaptation projects. Key definitions are provided, including terms like "responsible party" and "disadvantaged community," with a mandate that at least 40% of the disbursements benefit disadvantaged communities. The Pollution Control Agency's commissioner is responsible for determining liability, imposing cost-recovery demands, and disbursing funds for eligible projects. The bill also emphasizes local employment by requiring that contracts for adaptation projects adhere to prevailing wage standards.

Furthermore, the bill mandates the state auditor to assess costs incurred by the state due to greenhouse gas emissions and to report on the program's financial activities biennially. New provisions allow for fiscal audits of the program's account and expenditures, ensuring accountability and transparency. Appropriations from the general fund for fiscal year 2027 are included to support the commissioner of the Pollution Control Agency and the state auditor in implementing the program, covering staffing, administrative support, and hiring necessary consultants. This financial backing aims to enhance the program's effectiveness in combating greenhouse gas pollution.
