California climate law overview
California has enacted a trio of landmark climate laws – SB-253, SB-261, and AB-1305 – that significantly expand corporate climate disclosure requirements for businesses operating in the state. These laws are poised to influence national and global sustainability reporting practices.
Why it matters
With California’s climate disclosure laws on the horizon, companies with operations in California should carefully evaluate their sustainability readiness to reduce risk and avoid penalties. Non-compliance could lead to fines up to $500,000 per year. But beyond penalties, it’s about reputational risk and missing out on investor confidence.
