Business Groups Ask Supreme Court to Block California Climate Laws
The U.S. Chamber of Commerce has filed an emergency appeal with the Supreme Court seeking to halt California’s groundbreaking climate disclosure laws, arguing they violate corporate free-speech rights.
Key Takeaways
- California laws require large companies to report emissions and climate risks starting 2026
- Business groups claim laws violate First Amendment rights
- Laws affect thousands of companies with $1B+ and $500M+ revenue thresholds
- Supreme Court’s conservative majority may be sympathetic to business arguments
Legal Battle Over Climate Disclosure
In a dramatic move, the Chamber of Commerce and other business organizations asked the Supreme Court on Friday to pause what they call “the most sweeping” climate reporting requirements in the nation. The emergency appeal comes after lower courts refused to block the laws, which Democratic Governor Gavin Newsom signed in 2023.
The business coalition argues that California’s “unconstitutional efforts to slant public debate through compelled speech will take effect and inflict irreparable harm on thousands of companies across the country.”
What the Laws Require
First Law (SB 253): Companies with over $1 billion in annual revenue operating in California must report:
- Direct carbon emissions from 2026
- Indirect emissions from supply chains and business travel from 2027
- Affects 2,600-5,000 companies (state vs. Chamber estimates)
Second Law (SB 261): Companies with over $500 million in revenue must disclose:
- Climate-related financial risks every two years
- Impacts more than 4,100 companies according to state estimates
Companies failing to comply face civil penalties. ExxonMobil has separately challenged the laws in a recent lawsuit.
Constitutional Clash
California contends the laws don’t violate the First Amendment because commercial speech receives different constitutional protection. Governor Newsom has defended the measures as “bold responses to the climate crisis, turning information transparency into climate action.”
The environmental group Ceres supports the laws, arguing the disclosures will help consumers and investors make informed decisions about which businesses to support.
Broader Regulatory Context
The legal battle occurs amid broader uncertainty about climate disclosure requirements. The U.S. Securities and Exchange Commission approved a similar rule for public companies last year but paused implementation due to litigation.
The Supreme Court’s conservative majority has recently shown skepticism toward environmental regulations, including limiting EPA authority over power plant emissions in 2022 and blocking the “good neighbor” air pollution rule.
The outcome could set a crucial precedent for and corporate disclosure requirements nationwide.
