SB2691 AN ACT to amend Tennessee Code Annotated, Title 4; Title 5; Title 6; Title 7; Title 8; Title 39; Title 42; Title 43; Title 44; Title 55; Title 58; Title 59; Title 60; Title 65; Title 68 and Title 69, relative to environmental protection. 1 Jul 2024 Passed
Tennessee's geoengineering ban includes legislative findings asserting that federal atmospheric experiments may occur in the state, while its own fiscal analysis assumes no such activities are happening or will occur, creating an unusual disconnect between the stated justification and the projected impact.

2025-2026 Regular Session Session Adjourn Fri 24 Apr 2026
HB0899 AN ACT to amend Tennessee Code Annotated, Title 47, Chapter 18 and Title 68, Chapter 201, relative to weather modification. 1 Jul 2025 Introduced
Tennessee's bill takes an unusual enforcement approach by routing weather modification violations through consumer protection law rather than creating direct criminal prohibitions, treating cloud seeding as essentially a form of commercial fraud. The narrow application only to "weather-related companies" makes a significant gap—the same activities would remain legal if conducted by entities outside this defined category. Last update
Fri 14 Feb 2025
  Status: Held in Agriculture & Natural Resources Subcommittee since Feb 2025
HB1112 AN ACT to amend Tennessee Code Annotated, Title 58, Chapter 2 and Title 68, Chapter 201, relative to weather modification. 1 Jul 2025 Engrossed
Tennessee's HB 1112 creates one of the more aggressive enforcement frameworks among state weather modification bills, combining criminal misdemeanour charges with a substantial $100,000-per-violation administrative fine and extending liability up the supply chain to anyone providing materials with knowledge of their intended use. The bill has already passed the House 69-21 and crossed over to the Senate. Last update
Wed 26 Mar 2025
  Status: Passed by House, in Senate awaiting committee assignment
