California
California ranks third in the nation in industrial emissions. The state’s sixteen refineries account for thirty-seven percent of industrial emissions. Other high-emitting sectors include petroleum and gas systems, non-fluorinated chemicals, and minerals. Hydrogen production generates virtually all the emissions in the chemical sector. Cement production is responsible for nearly 90 percent of emissions from the minerals sector. Industry is clustered in the Bay Area, southern California, and the Central Valley.
- The top 20 emitters are shown on this map, coded by industrial sector. The size of the circles corresponds to emissions: the larger the circle, the higher the emissions.
- Disadvantaged communities (as determined by the federal government) are shaded blue.
- The inner circle provides a visual representation of the share of emissions generated by each industrial sector.
- The outer circle also indicates the share of a sector’s emissions generated in disadvantaged communities.
Examples of recently enacted legislation:
- In 2023, AB 43 amended the Health and Safety Code to address greenhouse gas emissions in California’s building materials sector, stating the intent to enact future legislation establishing a Low Carbon Product Standard for building materials.
- In 2023, SCR 21 urged the Alliance for Renewable Clean Hydrogen Energy Systems (ARCHES) to prioritize renewable, clean hydrogen for California. It emphasized the importance of prioritizing the hardest-to-abate sectors with the largest emissions profiles to help create economically sustainable markets.
- In 2024, AB 2731 amended the California Pollution Control Financing Authority Act, which presently allows the Authority to finance eligible projects or pollution control facilities aimed at preventing or reducing environmental pollution, to include qualified carbon dioxide capture facilities.
California has enacted a range of legislation that supports industrial decarbonization, including clean hydrogen production, sustainable procurement, and carbon capture.
