Loan guarantees are available to California small businesses and qualified nonprofits with up to 750 employees.
The Bay Area Air District facilitates the Climate Tech Finance loan guarantee by partnering with IBank to help climate tech companies secure financing. The program evaluates projects for greenhouse gas reduction impact, connects companies with lenders, and reduces lender risk by guaranteeing up to 80% of loans.
Climate Tech Finance offers loan guarantees of up to $5 million on loans up to $20 million, with up to a 7-year term (the loan term can be longer).
The interest rates for small businesses are determined by many external and internal factors and banks are generally free to set up their own interest rate.
IBank interest rates for public entities are set based on a combination of an Interest Rate Benchmark and Interest Rate Adjustments, which are dependent upon the repayment source. The Interest Rate Benchmark will be based on the Thompson's Municipal Market Data Index (MMD) and use published letter category ratings for the pledged revenue stream to determine the base (market price) spread from the MMD AAA GO Scale applicable to the borrower. Interest Rate Adjustments will cause the interest rate on financings to generally be below the Interest Rate Benchmark.
