Regional Collaboration and Shared Staffing Models. Local governments can partner with regional agencies to jointly develop GHG inventories, CAP components, and CEQA or planning tools, standardizing methodologies and sharing data to reduce duplication and cost. Regional or pooled staffing models allow smaller and under-resourced jurisdictions to share technical capacity for CAP updates, compliance tracking, and implementation, improving alignment with state frameworks and sustaining program delivery despite limited local staff.
