New California Climate Laws — Navigating the Regulatory Environment

The Race to Climate and GHG Regulations

California passed landmark legislation requiring large businesses to disclose their greenhouse gas emissions and climate-related business risks. While companies working in California with under $500 million in revenue are not subject to these new laws, smaller companies will likely experience increased pressure, as larger companies work to accurately calculate their Scope 3 GHG emissions. The new rules take effect in 2026.
