Governor Green signed SB 2999, establishing a Clean Fuel Standard for Hawaii's transportation sector. The law requires fuel carbon intensity to drop at least 10% below 2019 levels by 2035 and 50% by 2045. It uses a credit-deficit system to reward cleaner fuels without mandating a specific technology. The Hawaii Department of Transportation will enforce the standard through public rulemaking, with full implementation by January 2028. The legislation also includes HB 2021, which creates statewide safety rules for e-bikes and micro-mobility devices after a record number of traffic fatalities in 2025. Other signed bills cover traffic safety, housing, and school facilities. The Clean Fuel Standard aims to support local agriculture and renewable energy industries by expanding markets for homegrown renewable fuels and waste-to-energy options.
