IA SF2427

Shields defendants from civil and criminal liability for damages or injuries allegedly caused by greenhouse gas emissions' effects on climate.

Covers emissions from agricultural sources (farms producing, storing, or processing commodities) and renewable fuel sources, as well as specific gases including carbon dioxide, methane, nitrous oxide, and hydrofluorocarbons.

Liability protection applies unless a district court finds by clear and convincing evidence that the defendant violated an enforceable statutory limitation on greenhouse gas emissions or an express term of an operating/air permit issued by the Iowa DNR or a federal agency like the EPA.

Plaintiffs must specify each greenhouse gas emitted and demonstrate unavoidable, identifiable damage directly caused by the defendant's permit or statutory violation.

Explicitly states the chapter does not create any new right to bring climate-related lawsuits or judicial remedies.
