Global economic and climate policy leaders agree: the long-term resilience of both local and global economies hinges on their ability to manage and withstand climate-related risks. The state of California is now mandating compliance.
Climate Risk Mandates in California
California has long been recognized as a global leader in climate-risk policy, a reputation that aligns with its geographic vulnerability and frequent weather-related emergencies. As climate change intensifies and natural disasters become more frequent, it’s no surprise that the state has introduced new legislation that mandates certain companies disclose their annual climate-related financial risk to the public.
Effective January 1, 2026, Senate Bill No.261 (SB 261) requires companies to identify physical climate risks such as wildfires, floods, and extreme heat, in addition to transition risks like policy, market, and technology changes.
Who is Affected by SB 261
SB 261 applies to any company, other than insurers with annual global revenue exceeding $500 million, that conducts business in California. For those who are affected, compliance is generally defined as either 25% of total sales, property, or payroll, or for companies actively engaged in transactions for financial gain in California.

What This Means For You
SB 261 signals a broader shift in how climate risk is being treated, not just as an environmental issue, but as a financial one with real monetary implications. Companies are already feeling the impact, rising insurance costs, shrinking coverage in high-risk areas, and declining asset reliability are putting pressure on financial performance. For those operating in California, this legislation makes climate-risk disclosure a legal requirement starting January 1, 2026. With that date quickly approaching, building robust reporting processes will help avoid last-minute compliance risks. For those outside its scope, SB 261 is indicative of a growing wave of global climate disclosure mandates, with similar frameworks emerging from regulators in the U.S., Canada, and the EU.
