Hawaii Governor Josh Green signed two key pieces of climate and transportation legislation into law. SB 2999 establishes a statewide Clean Fuel Standard that requires transportation fuel carbon intensity to drop at least 10% below 2019 levels by 2035 and 50% by 2045. The program uses a credit-deficit system to incentivize lower-carbon fuels without mandating specific technologies. The Hawaii Department of Transportation must implement the standard by January 1, 2028. HB 2021 creates uniform statewide rules for electric bicycles and micro-mobility devices, including definitions, safety requirements, helmet rules for minors, and clearer enforcement authority. The law aims to close safety gaps as e-bike use grows rapidly in the state. Both bills are part of Hawaii's broader push to cut transportation emissions, which remains the state's largest source of greenhouse gases.
