Mississippi geoengineering ban; enact.

SB 2254 would have banned geoengineering activities in Mississippi by defining "geoengineering" as intentionally releasing chemicals into the atmosphere to alter weather, temperature, or sunlight. It would have prohibited such activities statewide and granted the Mississippi Commission on Environmental Quality authority to issue enforcement orders and impose penalties for violations. The bill directly affected entities or individuals attempting atmospheric interventions within Mississippi, including private companies or government entities. The legislation never became law, as it died in committee on February 3, 2026.
