Geoengineering Bills by State
2026 Regular Session
Adjourned Session ended May 15, 2026

|---|---|---|---|---|
|
2023 Regular Session
|
||||
| SB84 | Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances | Died in committee | ||
| A sprawling "Freedom to Farm" bill that bans weather modification while simultaneously stripping the governor of emergency food control powers and immunising farmers from nuisance suits and product liability claims. The environmental manipulation ban is almost incidental to the bill's broader agenda of insulating agricultural operations from government oversight. |

2024 Regular Session
|
||||
| SB1318 | Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances | Died in committee | ||
| A near-verbatim reintroduction of the previous session's failed "Freedom to Farm Act," now sponsored by Senator Moon instead of Senator Carter, with only the licensing cutoff date updated from 2023 to 2024. The weather modification ban remains buried within a broader agricultural deregulation package. |

2025 Regular Session
Session Adjourn Thu 15 May 2025
|
||||
| HB78 | Grants the air conservation commission the authority to create standards and guidelines | Sine die | ||
| A minimalist atmospheric modification ban that prohibits intentional weather and climate intervention but punts all enforcement details to the Air Conservation Commission through rulemaking - a sharp contrast to Missouri's sprawling "Freedom to Farm Act" attempts that bundle weather modification bans with agricultural deregulation. |

| SB297 | Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances | Sine die | ||
| Senator Moon's third consecutive attempt at the "Freedom to Farm Act," now entering the 103rd General Assembly with only a date change from its two failed predecessors. The persistent reintroduction suggests either strong constituent interest or the sponsor's personal commitment, but the lack of any substantive amendments after two committee deaths raises questions about prospects for breakthrough. |

2025 1st Special Session
|
||||
| SB15 | Prohibits any form of environmental manipulation | Sine die | ||
| Senator Moon strips the environmental manipulation ban from his repeatedly-failed "Freedom to Farm Act" and reintroduces it as a standalone two-page bill during a special session - identical definitional language, identical civil-only enforcement, but without the agricultural deregulation baggage that may have doomed previous attempts. |
