California State Capitol by Andre m

Existing law, the California Global Warming Solutions Act of 2006 (Act) designates the State Air Resources Board (ARB) as the state agency responsible for monitoring and regulating sources emitting greenhouse gases (GHGs). The Act requires the ARB to prepare and approve a Scoping Plan for achieving the maximum technologically feasible and cost-effective reductions in GHGs and to update the scoping plan at least once every 5 years.

This bill would require the ARB, before January 1, 2028, to develop and publish, on its website, a report on GHG emission inventories for the calendar year 2025 for each city, county, city and county, and special district. The bill would require the ARB, consistent with the preparation of the updates to the Scoping Plan and before January 1, 2033, and every 5 years thereafter, to update the inventories for the subsequent calendar years. The bill would authorize the ARB to solicit bids and enter into contracts for the development of the inventories. The bill would require the ARB, before January 1, 2026, to establish a local government advisory committee to inform its development of the GHG emission inventories. The bill would allocate, upon appropriation by the Legislature, $2,500,000 in the 2024–25 fiscal year for above-described purposes.

Committee Location: Senate Environmental Quality Committee; set for a March 29 hearing.
