California Air Resources Board Signals Intentions for Climate Regulations
At their August 21st public workshop, California’s Air Resources Board (CARB) significantly advanced implementation of the state’s climate disclosure laws. We are in the countdown!
These are SB 253 (Corporate GHG Reporting), SB 261 (Climate-Related Financial Risk Disclosure), and SB 219 amendments. Aimed at large companies formed in the U.S. and doing business in California, these require disclosure of greenhouse gas (GHG) emissions and climate-related financial risks starting in 2026.
Four months remain in 2025 for companies to prepare a first climate risk assessment for reporting. Companies have 10 months to compile Corporate Scope 1 and 2 reporting in mid-June, 2026.
NEW: CARB’s Current Regulatory Direction
For public comment, CARB provided their current thinking on draft rule language identifying a wide range of key details for implementation of the ‘200s’, as they referred to the 3 laws.

Do you represent one of the 10,000 companies in the U.S. doing business in California that will be affected by sweeping new climate-related disclosure requirements recently signed into law?
California requirements for public disclosures cover corporate climate-related financial risk (SB 261) and corporate GHG emissions/targets (SB 253). While these state climate disclosure laws are subject to court challenges, they are still in effect, so companies are collecting data now.
If you reply yes to the questions below, you must report your company’s Climate Disclosure starting in 2026.
This live educational webinar will highlight these new disclosure requirements for climate disclosures, apply the standards, and provide the related assurance requirements for each. This one-hour webinar is free and relevant to all industries. Meet our panelists.
Our panelists will explain the carbon accounting expectations, materiality considerations, and what to do now to prepare. We’ll provide an update on the net impact of timely court decisions affecting California requirements, as well as the impact of similar disclosure requirements under the CSRD rules of the European Union. It’s free with a Q&A forum, it’s non-commercial, and we respect your privacy!
Start or refine your roadmap for the journey to mandatory reporting and reflect upon the relationship of these disclosures to U.S. firms remaining globally competitive.

California is one of the world’s largest economies and drives national and global change. Two new state climate laws have been passed that address climate change’s physical, human, and financial risks. The Climate Corporate Data Accountability Act (SB 253) and The Climate-Related Financial Risk Act (SB 261) impact thousands of organizations that do business in California and must provide assurance-ready carbon emissions data — including reporting on scope 3 emissions from up and down their value chains.
Businesses are already implementing changes to meet the demands of these emerging regulations that cement the shift from voluntary climate reporting to mandatory reporting. Corporate leaders continue to develop strong climate reporting capabilities with audit-ready carbon accounting. They will be well-positioned to meet these California requirements and similar regulations emerging around the globe.
If you’re a large company doing business in California, you must begin gathering emissions data now to meet reporting requirements. Please join SCS Engineers for an A&WMA webinar that will help your company prepare your climate data and the internal processes and controls to manage it for these new regulations.
SB 253 affects public and private businesses with more than $1B in total revenue and doing business in California. SB 261 affects public and private businesses with more than $500M in total revenue and doing business in California.

Navigating U.S. Climate Emissions And Risk Disclosure Requirements: California Leads The Way
Join the Air and Waste Management Association (A&WMA) on March 19th for a 90-minute discussion of the sweeping new climate-related disclosure requirements covering climate risk and greenhouse gas emissions (GHG) finalized by the U.S. Securities and Exchange Commission (“SEC”) and the state of California in 2024. Both are subject to court challenges, with the implementation of the SEC rules now paused.
California’s laws have not been paused.
This presentation presents who is affected, the need-to-know elements of these new state and federal disclosure requirements, and what to do to prepare. Bonus material will be provided for climate and carbon requirements in the EU.
Thousands of organizations that do business in California will now have to provide assurance-ready carbon emissions data — including reporting on scope 3 emissions from up and down their value chains. California’s new laws cement the shift from voluntary climate reporting to mandatory reporting, raising the bar for corporate climate action. Corporate leaders who develop strong climate reporting capabilities with audit-ready carbon accounting will be best positioned to meet these California requirements and similar regulations emerging around the globe.
