CA SB100

Creates the Climate Catalyst Revolving Loan Fund within the State Treasury to provide low-interest financing for climate projects, administered by the California Infrastructure and Economic Development Bank.

Defines "climate catalyst projects" as buildings, infrastructure, equipment, or activities within California that further climate goals, reduce climate risk, and implement low-carbon technology.

Requires the Strategic Growth Council to advise the Legislature annually beginning in 2020 on priority categories of climate projects and requires the bank to submit annual reports on fund activities to the Legislature and Governor.

Increases the total outstanding bond authority for the Infrastructure and Economic Development Bank from $15 billion combined ($5 billion for public development facilities and $10 billion for rate reduction bonds) to $15 billion total for both types.

Expands the bank board's authority to establish small business finance programs directly, in conjunction with financial institutions, or through special purpose entities, in addition to existing contracting arrangements.
