State support for UC Berkeley’s GHG Inventory Tool

The CoolClimate Network at UC Berkeley is developing a data platform for GHG inventories and climate action metrics for local governments across California. The project was presented at CCEC 2024 and 2025 to gather input from participants. The outputs available to cities and counties (unincorporated counties are in the works) include traditional and consumption based inventories from 2010-2022. They also feature tangible metrics such as EV registrations with the DMV and heat pumps installed through TECH incentives. These detailed metrics are more informative and actionable for implementation than overall GHG emissions. They enable local governments to set concrete targets and tell compelling stories about climate action, benefits, and potential impacts in their communities. The emphasis on these metrics reflects the emerging trends of climate action practice, which seeks to be more relatable to people and integrated with equitable community benefits. 

The climate action data tool allows local governments to more efficiently conduct GHG inventories and evolve their climate action efforts and communications to focus on community benefits. The practice of local government climate action was originally established in the mid 2000’s in response to a lack of federal leadership. The current context calls us not only to continue but become more effective while delivering quantifiable social benefits and having the metrics to tell compelling stories.

CARB staff and contractors participate in the project’s advisory group and are evaluating whether this tool will meet the needs of local governments.
