HF 2527 Iowa House · 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.

HF 2527 would limit legal liability for businesses in agriculture, oil, or renewable fuels if sued over climate impacts from their greenhouse gas emissions. It blocks civil or criminal lawsuits claiming damage from emissions unless the business violated specific state emission rules or permits. Plaintiffs must prove clear evidence of direct harm from such violations, not just general climate effects. The law applies to all climate-related claims but does not create new legal rights to sue.
