Iowa 2025-2026 Regular Session

Iowa House Bill HSB693

Introduced
2/9/26  

Caption

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.(See HF 2527.)

Impact

The introduction of HSB693 could significantly impact how climate-related damages are litigated in Iowa. By restricting the grounds under which parties can sue for climate-related harms, this bill may reduce the number of claims filed against agricultural and renewable fuel entities. On one hand, proponents argue that this legislative measure is necessary to protect businesses from potentially frivolous lawsuits that could arise from the complex issue of climate change impacts. On the other hand, critics express concern that it may hinder accountability and limit the ability of individuals and communities to seek justice for legitimate harm caused by greenhouse gas emissions.

Summary

House Study Bill 693 aims to limit civil and criminal liability arising from alleged climate effects associated with greenhouse gas emissions. The bill specifies that in any civil or criminal action, a defendant will not be held liable if the action is based on claims related to greenhouse gas emissions unless clear and convincing evidence shows a violation of applicable regulatory statutes or permits. This introduces a structured definition of what constitutes a greenhouse gas and establishes the parameters under which liability can be assessed.

Contention

Notable points of contention surrounding HSB693 include debates about the balance between economic development and environmental responsibility. Opponents of the bill argue that it creates an environment that favors corporations over public health and environmental protections. They suggest that easing liability may discourage industries from adopting more sustainable practices or contributing to climate change mitigation efforts. Supporters, however, believe that the bill is a necessary step towards economic resilience, particularly for sectors heavily reliant on agriculture and renewable fuels, which may be adversely impacted by stringent climate liability claims.
