How to Prepare for 2026 California Climate Disclosure, with CARB Assistant Division Chief, Sydney Vergis
November 13, 2025 @ 2:00 pm – 3:00 pm EST
About this Event:
With the California Air Resources Board (CARB) set to finalize implementation rules for the state’s landmark climate disclosure laws—the Climate Corporate Data Accountability Act (formerly SB 253) and the Climate-related Financial Risk Act (formerly SB 261)—by year-end, the clock is ticking for companies required to comply in 2026.
The Climate Corporate Data Accountability Act requires large companies doing business in California to publicly disclose their greenhouse gas (GHG) emissions. The Climate-Related Financial Risk Act mandates climate risk disclosures aligned with frameworks such as TCFD or ISSB’s IFRS S2 Climate-Related Disclosure. These laws impose new data, assurance, strategy and governance expectations to integrate climate considerations into business planning. The session will deliver an overview of the laws’ development timeline and key requirements, including agency insight on program goals and application.
Join Workiva industry principal Alyssa Zucker for a live discussion with assistant division chief of the California Air Resources Board, Sydney Vergis, Ph.D. on critical first year reporting requirements, and expectations for future disclosure.
We will break down:
- Key elements of CARB’s proposed regulations and guidance
- The latest deadlines and reporting expectations for 2026
- How to determine if your company falls under SB 253 or SB 261
- What to expect from CARB’s forthcoming templates, public registries, and assurance requirements
The session will also include a moderated Q&A to address common questions regarding scope, applicability, data requirements, reporting structure, and alignment with global frameworks and reporting mandates.
After attending this session, participants will be able to:
- Assess Applicability: Understand proposed definitions of “doing business in California” and revenue thresholds determining applicability for SB 253 and SB 261.
- Navigate Reporting Requirements: Identify minimum reporting requirements for first year disclosure, and what remains TBD for future years.
- Prepare for Assurance: Grasp the phased- limited and reasonable assurance requirements for emissions disclosure.
- Leverage Official Resources: Receive a direct overview of templates, guidance, and resources available from CARB.
Workiva offers one CPE credit for this session.
