HB 1318 prohibits South Dakota from engaging with or investing in "natural asset companies," defined as for-profit entities that manage ecological resources like soil, biodiversity, or water quality for financial gain. The bill bans state contracts, investments, and bonds involving these companies, prohibits them from operating in the state, and voids any contracts entered after July 1, 2026. It also requires the Secretary of State to revoke business licenses for such companies and prevents natural assets (e.g., land, water rights) from being transferred to them. The law applies broadly to corporations and LLCs classified as natural asset companies but excludes state retirement systems and investment councils.

HB 1294 prohibits any person from conducting geoengineering within South Dakota. The bill defines geoengineering as large-scale climate interventions, specifically including carbon dioxide removal or reflecting sunlight away from Earth. Violating this prohibition is classified as a Class 6 felony. This law directly affects individuals or entities attempting these specific climate interventions within the state. The bill establishes a clear criminal penalty for such actions, focusing on preventing large-scale atmospheric or oceanic climate modification.

HB 1157 creates a 12-member task force to study ecological damage and costs from aquatic invasive species in South Dakota. The task force includes representatives from state agencies (Game, Fish and Parks; Agriculture; Tourism), tribal organizations, water development districts, recreation industries, and environmental groups. It must submit a report by November 2026 detailing prevention strategies, cost estimates, and funding recommendations for addressing invasive species. The bill appropriates $50,000 from the general fund for task force expenses and declares an emergency to expedite implementation.
