SF 2427 Iowa Senate · 2025-2026 Regular Session

A bill for an act providing a limitation on civil or criminal liability for any alleged actual or potential effect on climate caused wholly or partly by a greenhouse gas emission.

This bill limits civil or criminal liability for climate effects linked to greenhouse gas emissions from specific sources. It shields defendants (like farms, renewable fuel operations, or other facilities) from lawsuits claiming harm from emissions of gases such as carbon dioxide, methane, or nitrous oxide - unless a court finds they violated specific emission limits or permit terms. To override this protection, a plaintiff must prove by "clear and convincing evidence" that the defendant broke an enforceable state emission rule or permit condition. The bill explicitly states it does not create new legal rights to sue over climate impacts.
