Your path to California climate reporting starts here.
California’s new climate disclosure laws, SB 253 and SB 261, will soon reshape how companies doing business in the state report on greenhouse gas emissions and sustainability practices. With requirements taking effect January 1, 2026, now is the time to prepare. For many organizations, the challenge isn’t just knowing what CARB requires, it’s finding a clear, practical way to comply. Weaver’s sustainability team shares timely insights, practical guidance and tools to help you understand your obligations and take the right steps today.
CARB developed a checklist to provide additional direction to organizations.
Key Questions About California Climate Compliance
The new California requirements raise immediate questions about who is impacted, what data must be reported and how much time organizations really have to prepare. The following Q&A addresses these key issues to help you start planning with clarity.
Does my company fall under the new CARB disclosure requirements?
If your organization is registered to do business in California, you may fall under the state’s new climate disclosure laws. Not-for-profit organizations are exempt, among several other sectors, but most industrial, manufacturing and large private companies with a California presence will be required to comply.
What data will we need to collect and verify to stay compliant?
CARB requires detailed greenhouse gas (GHG) emissions data across scope 1, 2 and eventually scope 3, depending on the threshold. This includes energy use, emissions from facilities and in many cases, indirect emissions from your supply chain.
How much time and investment will compliance require?
The timeline is shorter than you may expect with January 1, 2026, as the new reporting deadline. Developing reliable data systems, engaging third-party assurance providers and aligning internal resources should begin now to avoid costly delays in 2026.
