| 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. |

| 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. |
