The clean fuels credit account is created in the state treasury. All receipts from clean fuel credits generated under this chapter by state agency activities not funded through an appropriation in an omnibus transportation appropriations act must be deposited into the account. Moneys in the account may be spent only after appropriation. Expenditures from the account may be used only for state agencies to complete investments to reduce state agency transportation-related emissions including, but not limited to, electric vehicle infrastructure, electric vehicles, electric vessels, and electric boats.
