Californias Climate Disclosure Laws Face Legal Stay: What Companies Need to Know

California is at the heart of a real tug-of-war over climate regulations this year — and it’s not just about the planet, but also about big business compliance. On November 18, 2025, the U.S. Ninth Circuit Court handed down a surprise move, pausing enforcement of a major climate-related financial risk disclosure law, SB 261. This law would have required companies with over $500 million in revenue doing business in California to publicly report the financial risks they face from climate change.

This legal hold on SB 261 was ordered as the court awaits a full hearing on the case, brought by the U.S. Chamber of Commerce and others who say the law is unconstitutional. However, another related law, SB 253, which mandates greenhouse gas emissions reporting, remains in effect but with some easing on enforcement for the initial period.

What does this mean for companies?

Some practical impacts include:

  • SB 261’s enforcement is on pause, so companies are temporarily not required to publish biennial climate-related financial risk reports as initially mandated by January 1, 2026.

  • SB 253’s emissions reporting starts gearing up, but California Air Resources Board (CARB) is allowing leniency, especially around data completeness and verification for the first reporting year. Companies can submit existing Scope 1 and Scope 2 emissions data they already gather, and are not penalized for gaps if they are making good faith efforts.

  • CARB pushed the first formal reporting deadline for SB 253 emissions data from June to August 10, 2026, with further flexibility on templates and assurance requirements.

Breaking down the laws and compliance expectations

SB 261: Climate-Related Financial Risk Act

  • Targets large companies ($500M+ revenue) in California
  • Requires public disclosure of governance on climate risks, business impacts, mitigation measures, and financial planning around these risks
  • Initial reports were due January 1, 2026, but enforcement is paused due to the legal challenge

SB 253: Climate Corporate Data Accountability Act

  • Requires annual reporting of greenhouse gas emissions, starting June 2026
  • Focuses on Scope 1 (direct emissions) and Scope 2 (indirect emissions from purchased energy)
  • CARB rolled out draft reporting templates but use is optional for 2026

What are Scope 1 and 2 emissions?

Think of Scope 1 emissions as the gases a company directly pumps out through its own activities, like burning fuel on-site. Scope 2 emissions come from the energy companies buy, like electricity generated by coal plants.

Why the legal pushback?

The U.S. Chamber of Commerce argues these California laws overreach, hurting competitiveness and exceeding state authority, reflecting broader national debates on climate regulation.

What’s next for businesses?

Carrying on with reasonable compliance efforts makes good sense in this murky environment. Here’s a quick checklist:

  • Monitor legal developments on SB 261 to know when enforcement may resume.

  • Prepare and organize emissions data, especially Scope 1 and 2, to meet the August 2026 deadline.

  • Consider adopting the CARB’s draft templates to simplify future reporting, even if optional.

  • Communicate with stakeholders transparently about where the company stands on climate risk disclosures.

The bigger picture

California is pioneering efforts to make companies accountable for environmental impacts, setting the tone for other states and possibly federal regulations. While the path is legally complex and shifting, these laws underline an essential truth: climate risk is increasingly seen as a financial risk, and corporate transparency on this front is fast becoming the norm, not just the niche.

Backed by expert voices, these regulations aim to pull back the curtain on how businesses are affected by and responding to climate change — turning what might seem like a dry regulatory filing into a powerful narrative for investors and communities.

In this dance between innovation, compliance, and courts, companies that keep agility and clear communication top of mind will be best positioned to succeed — regardless of how the legal winds blow.

Stay tuned as California’s climate regulatory landscape evolves — it’s a story with big stakes for business and the planet alike.
