Client Alert: CARB Releases Multiple SB 253 2026 Reporting Resources for Upcoming November 10th Deadline

On September 1, 2026, The California Air Resources Board (CARB) released multiple resources for the CARB proposed November 10, 2026 greenhouse gas (GHG) emissions reporting deadline, required by Senate Bill (SB) 253. The key update is the introduction of two submittal options for 2026 reporting: a new voluntary Report Intake Platform, and the ability to submit reports and contact information via email. 

New CARB Resources 

• A voluntary 2026 Report Intake Platform that entities may choose to use. Use of this platform is not mandatory. Entities may also email emissions reports and contact information to climatedisclosure@arb.ca.gov. 

• A  Guidance Document for SB 253 2026 Reporting Submittals

• A video tutorial of the voluntary report intake platform

Acceptable Reporting Formats for 2026 

Entities may satisfy their 2026 reporting obligation by: 

• Submitting an existing annual report that includes Scope 1 and Scope 2 GHG emissions. 

• Submitting existing Scope 1 and Scope 2 data already reported to other programs or voluntary initiatives. 

• Using CARB’s Draft Scope 1 and Scope 2 GHG Reporting Template for reporting Scope 1 and Scope 2 data. 

• Submitting a statement of non-reporting (on company letterhead) if the entity was not collecting, and was not planning to collect, Scope 1 and Scope 2 data as of December 5, 2024, when the Enforcement Notice was issued.  

Emissions reports, non-reporting statements, and contact information may be submitted via the voluntary 2026 Report Intake Platform or emailed to climatedisclosure@arb.ca.gov. All emission reports or statements of non-reporting will be made public. 

Key Clarifications 

• Minimum reporting scope: For 2026, reporting entities submitting reports are only required to provide their annual Scope 1 and Scope 2 emissions. Additional details – methodology descriptions, data sources, global warming potential (GWP) values, emission factors, organizational boundaries, disaggregated emissions data by category and gas, and any assumptions used – are optional, not required. 

• Reporting template is voluntary: CARB’s Draft Scope 1 and Scope 2 GHG Reporting Template, posted on October 10, 2025, may be used, but its use is not mandatory for this cycle.  

• CARB will still accept submissions whether or not assurance has been obtained for the 2026 cycle. 

• CARB is currently developing the reporting requirements for 2027, and this guidance only applies to the 2026 reporting cycle.

The California Air Resources Board (CARB) is proposing to defer the current reporting deadline for CA SB 253 from August 10, 2026, to November 10, 2026. The regulation is undergoing revisions, and once the public comment period concludes, the deadline extension will become final.

Client Alert: California Senate Extends Climate Disclosure Reporting Deadline

The California Senate has voted to approve an amendment to California's climate disclosure laws, granting the California Air Resources Board (CARB) an additional six months to develop regulations related to the reporting of greenhouse gas emissions.

The amendment introduces several changes to California Health and Safety Code 38532 (introduced as California Senate Bill 253) and California Health and Safety Code 38533 (introduced as California Senate Bill 261). The proposed amendment was introduced as SB 219 and effectively extends the previous January 1, 2025, reporting deadline to July 1, 2025, for purposes of reporting out greenhouse gas emissions under California Health and Safety Code 38532 (CA SB 253). Currently, the reporting deadlines have not changed for California Health and Safety Code 38533 (CA SB 261).
