California Passes Landmark Emissions Transparency Law for Large Companies

California lawmakers passed legislation requiring large companies to disclose direct and indirect greenhouse gas emissions.

Thousands of public and private companies making over $1 billion annually would have to report emissions from operations and supply chains.

Supporters say it will increase transparency and push companies to cut emissions, but opponents argue it will be burdensome.

The bill would mandate more disclosure than proposed federal SEC climate risk rules.

If signed into law, companies would start reporting emissions in 2026, with regulations formulated by 2025.
