Clean fuel standard prompts lifecycle and cost questions; committee defers SB 2999
Summary
A joint Agriculture & Environment and Transportation hearing on SB 2999 examined a proposed clean fuel standard; DOT provided feasibility modeling showing small upfront per-gallon impacts under conservative scenarios, while opponents raised land, water and lifecycle-emissions concerns. The committee deferred the bill for further study.
SB 2999 would require the Department of Transportation to adopt rules by Jan. 1, 2028, to implement a clean fuel standard for alternative fuels. DOT provided initial feasibility modeling showing a range of possible price impacts at the pump (a conservative scenario projecting approximately 1.5¢–5¢ per gallon and moderate/aggressive scenarios projecting up to 5–20¢ per gallon), while testifiers including the Energy Justice Network cautioned that fuels created for combustion are not truly zero-emissions and that biofuels can carry land- and water-use and lifecycle emissions risks.
Supporters said CFS programs in other states have helped attract private investment in charging infrastructure, renewable fuels and electrification projects; critics said Hawaii's limited land and water resources and the potential need to import feedstocks create environmental trade-offs that must be assessed using lifecycle tools such as the GREET model. DOT and other witnesses discussed an opt-in approach for aviation and marine sectors because of federal preemption issues. Committee members asked for additional analysis of lifecycle carbon intensity, land-use implications and consumer-price impacts.
Given the complexity of trade-offs and outstanding modeling concerns, the committee deferred SB 2999 for additional study and stakeholder input.
What happens next: DOT was asked to provide expanded feasibility modeling and cost/benefit scenarios and the committee requested further clarifications on opt-in mechanics for aviation and marine sectors and lifecycle accounting.
