Alternative Fuel Standard Development
The state’s alternative fuels standard contains a non-binding goal of having alternative fuels provide 20% of highway fuel demand by 2020 and 30% by 2030. (Hawaii Revised Statutes 196-42)
Alternative Fuel and Advanced Vehicle Acquisition Requirements
State and county agencies must purchase light-duty vehicles that reduce petroleum consumption and meet the needs of the agency. State agencies must purchase alternative fuels and ethanol-blended gasoline when available. For more information, see the Hawaii State Energy Office’s Vehicle Purchasing Guidelines website. (Hawaii Revised Statutes 103D-412 and 196-9)
Alternative Fuel Tax Rate
Ethanol is taxed at .145 times the rate for diesel fuel on both the state and county level. State tax on ethanol is 2.4 cents per gallon while gasoline and diesel are 16 cpg. County taxes on ethanol/gas are: Hawaii – 1.3/8.8 cpg; Honolulu – 2.4/16.5 cpg; Kauai – 2.5/17 cpg; and Maui, 4.2/18 cpg. When those rates are applied, E10 is taxed 2.1 to 2.8 cents lower than straight gasoline.
