SB 253 (Wiener) Corporate Climate Data Accountability Act 

On October 7, 2023, Governor Newsom signed SB 253, the Climate Corporate Data Accountability Act, into law!

Thank you to Senator Scott Wiener, our partners at California Environmental Voters, and the thousands of Californians who stood up to fossil fuel corporations to get this bill over the finish line.

Many of the largest corporations doing business in California — which contribute the most to the climate crisis — are not transparent about their carbon footprint. SB 253 will change that. This law will require all large, U.S.-based corporations doing business in California that make more than $1 billion annually to publicly disclose their full carbon footprint in a way that is easily understandable and available to the public.

Without transparency, we can’t hold corporations accountable for their climate pollution. That’s why SB 253 is so important. Fossil fuel companies tried to kill this bill, but the climate movement fought back and won!
