CARB Confirms California Climate Risk Reports On Hold, Pending Appeal

December 2, 2025

On December 1, 2025, the California Air Resources Board (CARB), the regulatory body tasked with implementing and enforcing SB 261 and SB 253, confirmed that, in accordance with the Ninth Circuit’s order granting a partial injunction on November 18, 2025, it would not take enforcement action against any Covered Entity that does not post and submit a climate-related financial risk report pursuant to SB 261 by the January 1, 2026 statutory deadline.

Below are four questions to help companies determine the appropriate next steps.

How should I think about the Ninth Circuit order and CARB’s latest announcement?

As discussed in our blog post last week, the Ninth Circuit’s order granted a partial injunction against CARB’s ability to enforce SB 261 for the duration of the injunction, which lasts for the duration of the appeal (oral argument is set for January 9, 2026). SB 261, as codified in California’s Health and Safety Code section 38533, is still valid and effective at this time. CARB has confirmed in a new Enforcement Advisory on December 1, 2025 that Covered Entities will not be penalized for delaying the posting of its climate-related financial risk reports until the appeal has been resolved (although Covered Entities are still welcome to voluntarily post and submit their reports to CARB beginning December 1, 2025). At such time, CARB will provide additional information, including alternate deadlines for reporting in this first year, as appropriate. Until there has been confirmation that the legislation has been struck down or permanently stayed, a Covered Entity should still be prepared to submit its SB 261 report if and when the new deadlines are published.

SB 253, of course, was not impacted by the Ninth Circuit’s order, and Reporting Entities should be prepared to submit their GHG emissions reports in line with current proposed guidelines.

See our blog post last week for the latest information about how companies can determine if they are in-scope as either a Covered Entity for purposes of SB 261 or a Reporting Entity for purposes of SB 253.

How should I think about preparing for the SB 261 climate-related financial risk report?

At the November 18, 2025 working group session, CARB confirmed that it believes it has provided sufficient guidance for companies to prepare their climate-related financial risk reports under SB 261 and was not planning to publish further guidance besides the updated checklist it published as of November 17, 2025. During the working group session, CARB proposed updated guidance and clarified a few open points during the Q&A. Below is a summary of the latest guidance, which supplements the guidance laid out in our prior alert:

Topic Update 
Deadline

As a result of the Ninth Circuit order, the new deadline for SB 261 reports is still to be determined for this first year of compliance. CARB has previously confirmed that the extended timeline for finalizing the initial implementing regulations does not impact the deadline for first year reporting. As such, the new deadline could be set before or after the implementing regulations are approved, depending on how long the appeal takes.

Going forward, the legislation codifying SB 261 requires climate-related financial risk reports to be uploaded to each Covered Entity’s website by January 1 every other year, and CARB does not have any authority to change this date.

Website Posting Requirement

In response to comments received, CARB confirmed if a Covered Entity (e.g. a subsidiary entity) does not have its own website, it can make a new website or page for the purpose of posting the required climate-related financial risk report. However, CARB did not clarify that a subsidiary Covered Entity could post it on their parent company’s website.

Website Posting vs Docket Submission

Unlike the January 1, 2026 deadline for posting the reports on each Covered Entity’s website, the public docket through which links to the report must be submitted will remain open from December 1, 2025 to July 1, 2026. While this is to give Covered Entities additional time to submit the links, CARB refused to affirmatively approve multiple requests from participants at the November working group session to make further revisions and edits to the climate-related financial risk reports between the website posting deadline and the docket submission deadline.

Docket Submission Requirements

CARB opened the public docket to submit SB 261 reports on December 1, 2025. Although no longer required by January 1, 2026, Covered Entities can voluntarily post and submit their reports now. When making the submission, Covered Entities should keep in mind the following instructions:

  • Company statements should be on official letterhead and should use the following file naming convention: “CompanyName_Statement_date”.

  • For parent/subsidiaries submitting consolidated reports, the statement should include a list of Covered Entity subsidiaries that are using the report to satisfy their SB 261 reporting requirements.

  • The company statement should be uploaded as an attachment to the submission, while the link to the climate-related financial risk report can be submitted in the “Message” field of the submission form.

  • The submitter will need to provide their name and contact information in the submission form.

Minimum Requirements

Most of the prior guidance on the minimum requirements for climate-related financial risk reports for this first year of compliance has stayed the same since our prior alert: the accepted frameworks (including relevant industry-specific guidance), the required additional statements set forth by CARB, the four key principles to be covered (governance, strategy, risk management and metrics and targets) and the guidance around enforcement discretion for this first year all remain the same.

The main update is that Covered Entities that are still in the early stages of evaluating climate-related risks and may not have a full report ready by the deadline should nevertheless submit a report disclosing how climate-related risks relate or may be relevant to the Covered Entity’s business, even if no material risks have been identified or risk mitigation strategies and actions taken. This is in addition to the required descriptions about what components of the TCFD (or other approved framework) have been followed and not followed, and plans to address those gaps in the next report.

Additionally, while not strictly required, Covered Entities are encouraged to include a description of gaps, limitations, estimates and assumptions that were used and made in connection with the Covered Entity’s assessment of climate-related financial risks. Such disclosure is helpful not only to the market, but also helps protect the Covered Entity from potential disclosure liability risk.


What do I need to do to get ready for compliance with SB 253?

At the November working group session, CARB provided updates to its guidance on the greenhouse gas emissions reports required under SB 253 in 2026, which are summarized below. Guidance that has not changed since August/September can be found in our prior alert. Further guidance for future reports, including data assurance requirements, further enforcement provisions and recurring reporting deadlines after 2026, will be forthcoming later in 2026 after the initial implementing regulations are finalized.

Topic Update 
Deadline

The new deadline for the greenhouse gas emissions report covering Scope and Scope 2 emissions for this first year is August 10, 2026. Although subject to final approval by the CARB board in Q1 2026, we expect this deadline will be approved, as it is intended to align with the verification deadline under California’s Mandatory Greenhouse Gas Reporting Regulation. Future year deadlines will be established by subsequent rulemaking, so companies should not assume the 2027 deadline will also be August 10.

Period Covered for the 2026 Report

In short, most Reporting Entities will be required to produce fiscal year 2025 data in the report due August 10, 2026 (but may provide fiscal year 2026 data if preferred). Certain Reporting Entities with early fiscal year ends (on or before February 1, 2026) will be required to product fiscal year 2026 data in this first report. CARB’s stated intention with these cutoffs is to allow each Reporting Entity at least six months to compile the applicable data and finalize the report.

Report Requirements

As noted in the Enforcement Notice that CARB published on December 5, 2024,CARB will exercise its enforcement discretion for this first year of compliance and allow Reporting Entities some flexibility in complying with SB 253 requirements. Since existing practices of Reporting Entity companies vary widely as to the collection of greenhouse gas emissions data and preparation of such reports, during the November working group session, CARB presented a few different ways a Reporting Entity may satisfy the SB 253 reporting requirement in 2026:

  • If a Reporting Entity has an existing report that covers Scope 1 and Scope 2 emissions and was prepared in accordance with the Greenhouse Protocol (“GHG Protocol”), then the Reporting Entity can submit that report to satisfy the SB 253 requirement.

  • If a Reporting Entity already submits annual Scope and Scope 2 emissions data through another regulatory program or a voluntary program, then the Reporting Entity can submit that same information to CARB to satisfy the SB 253 requirement.

  • A Reporting Entity may choose to submit data using CARB’s Draft Scope 1 and 2 GHG Reporting Template, although use of this template is not required for the greenhouse gas emissions report due August 10, 2026. CARB has stated it does not plan to update this template, as its use is optional in the first year. CARB’s future guidance on SB 253 for subsequent reporting years may include a revised template.

  • If a Reporting Entity was not collecting Scope 1 and/or Scope 2 emissions data or was not planning to collect such data as of December 5, 2024 (the date of the Enforcement Notice), then such Reporting Entity is not required to submit Scope 1 and Scope 2 data for this first reporting cycle. However, they must submit a separate statement on company letterhead to CARB, stating that the Reporting Entity is not submitting a report and indicating that, in accordance with the Enforcement Notice, the Reporting Entity was not collecting such data or planning to collect such data at the time the Enforcement Notice was issued. CARB intends to open a public docket closer to August 10, 2026 that Reporting Entities should use to submit these statements.

Assurance Requirements

As part of CARB’s enforcement discretion, it will not object if limited assurance is not included this first year’s report, if a Reporting Entity does not have it ready in time. However, Reporting Entities that already have obtained limited assurance should still include it in their report. Reporting Entities with emissions data but not assurance should submit the emissions data report and are not required to submit a separate statement about not having assurance (although it may be helpful to note it in the report, for ease of CARB’s compliance review). CARB clarified that limited assurance will be required beginning in 2027 and the subsequent deadlines for when reasonable assurance will be required have not changed.

Request for Comment on Scope 3

Although not required in this first year’s report, CARB is soliciting feedback on which of the fifteen Scope 3 categories listed in the GHG Protocol are most used by companies and/or most helpful for investors and consumers, as it prepares implementing regulations for Scope 3 emissions reporting under SB 253. Comments should be sent to climatedisclosure@arb.ca.gov.


How should I think about reporting and compliance if I have multiple in-scope entities in my corporate structure?

A significant number of participants at CARB’s working group sessions this year have raised questions about how to comply with SB 253 and SB 261 when there may be multiple in-scope entities under one parent entity, when certain entities may be in-scope but not others (especially with respect to companies that have non-U.S.-based parent or subsidiary companies). Although a number of questions are still open and waiting for CARB’s response, there were some additional clarifications provided at the November working group session that supplements the parent/subsidiary relationship guidance that CARB previously proposed at its August working group session, which we summarized in our prior alert. We expect that CARB will have additional guidance forthcoming with respect to how to think about compliance in the context of parent/subsidiary relationships and multiple in-scope entity reporting. 

Topic Update 
Use of Consolidated Reports

CARB reiterated that only in-scope subsidiaries that are determined to be a “subsidiary” under California’s Cap-and-Invest program (the extended and renamed successor program to the original Cap-and-Trade program) can use their parent-level consolidated reports. If they do not satisfy those requirements, the in-scope subsidiary must prepare its own individual report.

Separately, CARB clarified that consolidated reports do not need to be limited to include only the consolidated data of in-scope entities: a consolidated report that includes data from an in-scope subsidiary and other not-in-scope subsidiaries can still be used to satisfy the requirements under both SB 261 and SB 253.

Subsidiary Submitting Parent-level Consolidated Reports

SB 219 allows parent companies to submit reports on their in-scope subsidiary’s behalf, even if the parent company itself is not an in-scope entity. However, CARB seems to take this literally (i.e., the parent can submit on behalf of the subsidiary) and declined to confirm when asked by participants during the November working group session that the in-scope subsidiary entity can itself submit a link to the parent company’s report. CARB did acknowledge the question, however, and noted they would put together some additional FAQs on this point.

Fees to be Paid

Fee invoices will be issued to in-scope entities after the CARB board adopts CARB’s proposed implementing regulations, which includes the proposed fee amounts. It is unclear how CARB will issue such fee invoices (for example, whether these will precede the submission of the required reports—particularly for the greenhouse gas emissions report under SB 253—or whether it will rely on company lists based on the FTB database or some other database). What is clear is that companies will not need to pay the annual fee until further notice from CARB.

CARB also reiterated that fees are assessed for each in-scope entity, and while parent companies can pay all owed fees in one combined payment, the amount must reflect the fees separately owed by each in-scope entity in that parent company’s corporate structure. This annual fee assessment applies for both SB 261 and SB 253, even though the report required under SB 261 is only bi-annual.


Next Steps for CARB

CARB will be presenting its final proposed implementing regulations to the CARB board for approval sometime during the first quarter of 2026. Although we expect the proposals should not significantly change between now and then, CARB is still considering feedback and comments that interested parties may submit through the CARB email address at climatedisclosure@arb.ca.gov. Once the notice package with the initial rulemaking is published, the public docket will be open for a 45-day comment period to solicit further comment. Following the approval and finalization of the first round of implementing regulations in the first quarter of 2026, CARB will continue to develop and propose additional implementing regulations for subsequent reports for SB 253.
