Environmental protection; prohibit chemtrails.

SB 2666 defined "geoengineering" as the intentional release of chemicals into the atmosphere to alter weather or sunlight, and prohibited such activities within Mississippi. The bill amended state environmental laws to grant the Mississippi Commission on Environmental Quality authority to enforce this prohibition, including issuing orders and imposing penalties for violations. This would have directly affected any entity conducting geoengineering within the state, including government agencies or private organizations. However, the bill died in committee on February 3, 2026, and did not become law.
