Local governments should align their Climate Action Plans with regional and state frameworks by partnering with regional agencies to standardize methodologies, share data, and reduce duplicated work. Regional collaborations—such as conducting regional GHG inventories, developing shared CEQA or planning guidelines, and aggregating climate data—can lower costs, increase economies of scale, and ensure consistent assumptions across jurisdictions. This integrated regional approach strengthens collaboration, improves plan alignment, and provides small or under-resourced jurisdictions with the technical support needed to meet state climate goals.
