California Climate Laws Update: CARB Workshop and SB 261 Pause 

Below is an excerpt from ISS-Corporate’s recently released article California Climate Laws Update: CARB Workshop and SB 261 Pause”. The full article is available on ISS-Corporate’s resources page.   

The California Air Resources Board (CARB) hosted its public workshop on November 18, 2025, to discuss the California Climate Accountability Package (CCAP). This was the third workshop hosted by CARB this year. For summaries of the first two workshops on May 29 and August 21 see ISS-Corporate’s coverage here (Workshop 1) and here (Workshop 2). 

The CCAP consists of two laws – collectively referred to as “the 200s” – that apply to companies doing business in California: 

  • SB 253: Requires annual disclosure of Scope 1, 2, and 3 greenhouse gas emissions. 
  • SB 261: Requires biennial reporting on climate-related financial risks. 

Also on November 18, the Ninth Circuit Court of Appeals issued an order temporarily pausing  SB 261, effectively putting the statutory deadline of January 1, 2026, on hold. A hearing scheduled for January 9, 2026.
