SB633 would amend Hawaii’s environmental response, energy, and food security tax to function as a phased-in carbon tax on fossil fuels. It renames the tax to the environmental response, energy, carbon emissions, and food security tax, raises the petroleum and fossil-fuel tax rates gradually beginning in 2026, and directs portions of the revenue to existing environmental, energy, transportation, and new special funds. The bill’s stated purpose is to reduce greenhouse gas emissions while avoiding a sudden price shock by starting with lower initial rates and increasing them over time.
The bill also creates a carbon cashback tax credit for individual taxpayers with gross annual household income up to roughly 80% of area median income, with larger refundable credits for lower-income households and joint filers. The credit is designed to offset the higher fuel costs caused by the carbon tax and is refundable, meaning eligible taxpayers can receive payment even if they owe no income tax. In addition, the bill establishes a carbon emissions tax and dividend special fund to pay for administration and outreach, and it reenacts the agricultural development and food security special fund to support farming, food production, and reduced reliance on imported food.
In practical terms, the bill would change state tax law by increasing distributor-level taxes on petroleum products and other fossil fuels, revising how those revenues are allocated, and creating new statutory funding streams for agriculture and carbon-dividend administration. It also requires annual reporting by the Department of Taxation and a later evaluation by the Office of Planning and Sustainable Development, giving the Legislature ongoing oversight and the ability to adjust the credit amounts in future years. The bill would apply the tax credit retroactively to taxable years beginning after December 31, 2024, while the higher carbon tax rates would begin on January 1, 2026.
The overall sentiment reflected in the bill text is strongly supportive of carbon pricing and progressive rebates. The findings cite economist support for carbon taxes and rely on a University of Hawaii study concluding that a carbon tax and dividend approach would reduce fossil fuel use and provide net benefits to most households, especially lower-income households. Because there are no committee transcripts or recorded votes provided, there is no documented opposition or support beyond the bill’s own policy framing.
The main points of potential contention are the size and pace of the tax increases, the effect on fuel and utility prices, and whether the refundable credits fully offset costs for lower-income residents. Another possible issue is the bill’s use of revenue for multiple purposes, including agriculture, environmental programs, and administration, which could draw scrutiny over fund allocation priorities. The bill also preserves certain exemptions and utility pass-through provisions, which may be relevant to electric utilities, gas utilities, and aviation and boating fuel users.
SB633 would substantially revise Chapter 243’s fuel tax structure by increasing the per-barrel and per-BTU tax rates over time and expanding the tax’s stated purpose to include carbon emissions reduction. It would also add new provisions to Chapters 141, 231, and 235 to create the agricultural development and food security special fund, the carbon emissions tax and dividend special fund, and the carbon cashback refundable tax credit, respectively. Existing environmental, energy, and development funds would continue to receive designated revenue shares, while new fixed-dollar deposits would be directed to agriculture and the carbon-dividend program. The bill would affect fossil fuel distributors, taxpayers eligible for the credit, the Department of Taxation, the Department of Agriculture, and agencies receiving dedicated fund deposits.
The bill is framed positively and policy-driven, with explicit legislative findings favoring carbon pricing, climate mitigation, and household rebates. Its stated rationale emphasizes emissions reduction, economic efficiency, and relief for lower-income residents, suggesting a generally favorable posture toward the proposal. No committee testimony or vote history was provided, so there is no recorded external sentiment to indicate organized support or opposition beyond the bill’s own findings and structure.
The likely areas of contention are the higher fuel tax burden, the gradual but significant rate increases, and the downstream effects on consumers, utilities, and businesses that rely on fossil fuels. Critics may question whether the refundable credits adequately protect households from higher energy costs, whether the revenue allocations are the best use of the proceeds, and whether the carbon tax should be implemented through the existing fuel tax framework. The bill’s exemptions for certain coal power purchase agreements and pass-through provisions for utilities could also be debated, as could the reenactment and funding level of the agricultural special fund.
