How Could a California Green Bank Help Accelerate Decarbonization?

This fact sheet by the Climate Policy Initiative explores how a proposed California green bank could accelerate the decarbonization of the transportation sector, which accounts for approximately 40 percent of the state's greenhouse gas (GHG) emissions. The document identifies specific financial and risk-bearing interventions across four subsectors: passenger vehicles, alternative fuel vehicle infrastructure, goods movement, and regional planning.

• The transportation sector is identified as California's most significant clean-energy challenge, contributing roughly 40 percent of the state's GHG emissions. Within this sector, passenger vehicles were responsible for approximately 71 percent of annual transportation GHG emissions between 2000 and 2011, representing 27 percent of California's total annual GHG emissions.
• A green bank could address barriers to zero-emission vehicle (ZEV) adoption for low-income households by providing credit enhancements to financiers. This would encourage lenders to offer loans that account for lower fuel costs and reduced default risk, expanding private lending for low-carbon vehicles.
• To overcome the 'chicken-and-egg' challenge of ZEV adoption and infrastructure availability, a green bank could coordinate risk and financing across multiple stakeholders, including power providers, auto manufacturers, and government agencies. Potential interventions include financing home charging stations for multi-family units, supporting projects with long payback periods, and coordinating the deployment of vehicle-grid-integration (VGI) technologies like distributed solar and energy storage.
• In the goods movement sector, heavy-duty vehicles contribute about 20 percent of California's transportation emissions (8% of total state emissions). A green bank could support the scale-up of disruptive infrastructure through long-term loans and insurance, and provide credit enhancements to help small business owner-operators, such as drayage truck drivers, finance low-carbon upgrades.
• For regional planning, a green bank could support the goals of the 2008 Sustainable Communities and Climate Protection Act (S.B. 375) by financing pilot car share programs to reduce vehicle miles traveled (VMT). This includes expanding services to suburbs and underserved communities, piloting multi-modal ZEVs like e-bikes, and offering insurance to businesses that reduce parking spaces to lower VMT.
