Ninth Circuit Rules on California Climate Disclosure Laws, Allows Scope 1 & 2 to Proceed

The U.S. Court of Appeals for the Ninth Circuit issued an opinion on California's Senate Bills 253 and 261, which mandate climate-related disclosures. The ruling allows Scope 1 and 2 greenhouse gas emissions disclosures under SB 253 to move forward, with a reporting deadline of November 10, 2026. However, the court indicated that Scope 3 disclosures under SB 253 and all of SB 261 are likely unconstitutional under the First Amendment and are expected to be enjoined.

Context

California's Senate Bills 253 and 261 aim to enhance climate-related disclosures by requiring companies to report their greenhouse gas emissions. Scope 1 and 2 emissions pertain to direct emissions from owned or controlled sources, while Scope 3 includes indirect emissions. The court's decision allows for the implementation of Scope 1 and 2 disclosures but raises constitutional concerns regarding Scope 3 and SB 261.

Why it matters

The Ninth Circuit's ruling on California's climate disclosure laws is significant as it establishes a legal framework for transparency in greenhouse gas emissions. This decision impacts how companies report their environmental impact, potentially influencing corporate behavior and accountability. The ruling may also set a precedent for similar legislation in other states, shaping the national conversation on climate change and corporate responsibility.

Implications

The ruling may lead to increased scrutiny of corporate emissions, encouraging companies to adopt more sustainable practices. Businesses that fail to comply with the new disclosure requirements could face legal and reputational risks. Furthermore, the decision may influence investor behavior, as stakeholders increasingly prioritize environmental transparency in their investment decisions.

What to watch

The reporting deadline for Scope 1 and 2 emissions is set for November 10, 2026, which will be a key date for companies to prepare their disclosures. Observers should monitor how businesses adapt to these requirements and the potential legal challenges that may arise regarding Scope 3 disclosures. Additionally, the response from environmental advocacy groups and other states considering similar laws will be important.
