| LD499 | An Act to Prohibit Geoengineering | Defeated (ONTP adopted) | ||
| Maine's geoengineering prohibition attempted to criminalise not just practitioners but also funders and authorizers of atmospheric intervention activities. The bill died in April 2025 after a divided committee vote and a floor rejection, despite receiving a fiscal note approving funding for a dedicated enforcement position. |

| LD825 | An Act to Prohibit Geoengineering, Including the Use of Cloud Seeding, Weather Modification, Excessive Radio Waves and Microwave Radiation | Defeated (ONTP adopted) | ||
| This broader Maine geoengineering bill attempted to regulate electromagnetic emissions down to the milligauss level and would have required the state to formally notify the federal government that it was banned from atmospheric activities over Maine. With $500,000 daily fines and felony penalties, it represented one of the more aggressive enforcement approaches seen in 2025 geoengineering legislation. |
