Hawaii becomes fifth state with a clean fuel standard

July 20, 2026 |

In Hawaii, Governor Josh Green, M.D. signed legislation to create a clean fuel standard for the State of Hawaii. This new law will help drive demand and open a new market for biodiesel, renewable diesel and sustainable aviation fuel while spurring economic opportunity and improving the health of its citizens.

SB2999 tasks the Hawaii Department of Transportation (HDOT) to develop regulations to reduce transportation emissions by 10% from 2019 levels by 2035 and no less than 50% by 2045. HDOT must adopt program rules by Jan. 1, 2028, with implementation beginning Jan. 1, 2029. This technology-neutral and market-based program will generate new opportunities for the fuels industry to help meet these carbon emissions reduction targets.
