Iowa AG leads brief against California climate reporting laws

Iowa Capital Dispatch

Iowa Attorney General Brenna Bird and attorneys general from 24 additional states are urging the U.S. Supreme Court to issue a stay on California emissions reporting laws.

The states allege, in the amici curiae filed, the California laws would impose an “illegal greenhouse gas disclosure policy” and would cause “nightmarish compliance costs and liability on companies across the country.”

In 2023, California enacted laws that require businesses of a certain size to submit greenhouse gas emissions reports and reports on the measures the business planned to adopt to reduce their climate-related financial risk.

The brief from the states said California is “trying to be the national regulator of American greenhouse gas emissions—but for many reasons it may not do so.”
