In Hawaii, gas taxes are the largest source of funding for the safety, upkeep, and improvement of public roads and bridges. The state gas tax is 16 cents per gallon. The federal government and counties also collect fuel taxes. As Hawaii gets closer to the goal of 100% clean energy by 2045, many people are buying more fuel-efficient cars and trucks. Fewer gallons of gas sold means less gas tax collected. RUC is a possible way we could pay for our roads and bridges in a future without gas taxes.
