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. (Formerly HSB 693.) Effective date: 07/01/2026.

The Iowa bill HF2527 limits the civil and criminal liability of individuals or businesses for any climate impacts that may be linked to greenhouse gas emissions. This means that if someone is accused of causing climate-related harm due to their emissions, they may have legal protections against lawsuits or criminal charges. The law will take effect on July 1, 2026.

Supporters of HF2527 argue that the bill encourages economic growth and innovation by protecting businesses from excessive litigation related to climate issues. They believe it provides a clearer framework for accountability and fosters a more business-friendly environment, ultimately benefiting the state's economy.

Critics of HF2527 contend that the bill undermines environmental protections and could allow harmful practices to continue without accountability. They argue that it may hinder efforts to combat climate change by shielding companies from responsibility for their contributions to greenhouse gas emissions.
