An Act To Prohibit Geoengineering

LD 499 prohibits individuals, organizations, or entities in Maine from conducting, authorizing, or funding any geoengineering activity, which includes climate-altering techniques like solar radiation management, stratospheric aerosol injection, cloud seeding, and carbon dioxide removal. The bill defines geoengineering as deliberate large-scale intervention in Earth's natural systems to counter climate change, with exemptions only for controlled scientific research approved by the Department of Environmental Protection (which must submit annual environmental impact reports). Violations constitute a Class E crime punishable by a $10,000 daily fine. This law directly affects anyone planning or funding such activities within Maine, excluding authorized research.
