What We’re About

Carbon Accountable is a climate data initiative dedicated to corporate transparency in greenhouse gas emissions reporting. With a focus on legal and technical support, Carbon Accountable works to ensure robust and effective climate legislation implementation.

The California-based mandatory corporate GHG emissions disclosure proposal developed by Carbon Accountable became California Climate Corporate Data Accountability Act (SB 253) authored by Senator Scott Wiener (D-11). Carbon Accountable acted as a bill co-sponsor and the main legal and technical advisor on the bill prior to its enactment into law in October 2023 and continues to work to ensure that the promise of SB 253 is realized.

There is no time to lose - companies need GHG emissions data to manage climate risks and inform their chosen decarbonization strategies and consumers and investors must have access to the climate data they need for decision making.
