The state should build a unified, easy-to-navigate system for producing, standardizing, and sharing local GHG and energy data. This would include: A centralized statewide energy and GHG data portal—potentially by expanding existing platforms like the UCLA Energy Atlas to serve all regions and remain up to date, and by restoring free access to key tools such as ICLEI ClearPath for local jurisdictions. Standardized GHG inventory methods, timelines, and indicators statewide, ensuring that all jurisdictions work from consistent, comparable (“apples-to-apples”) data. Regularly produced and published local GHG inventories for every city and county, updated on a predictable statewide cycle to reduce duplication, support regional planning, and inform state policy.
