  • Companies that have not been collecting GHG emissions data and are not planning to collect data, are not expected to submit Scope 1 and 2 reports in 2026 (they must submit an explanatory letter to CARB)
  • Assurance is not required for the first year 2026 reporting (although if the company has it and wishes to report it, they can do so)
  • Staff will be working on a subsequent rulemaking in 2026 to address program requirements in 2027 and other topics including reporting format and data assurance requirements
