A federal appeals court has temporarily blocked Hawaii from enforcing a new climate change tax on cruise ship passengers that was scheduled to take effect at the start of 2026.

The ruling, issued on New Year’s Eve by two judges on the 9th U.S. Circuit Court of Appeals, prevents the state from enforcing the tax while legal challenges proceed. The lawsuit was brought by Cruise Lines International Association (CLIA), which argues that the new fee violates the U.S. Constitution and would raise cruise prices.

The tax is part of a climate-focused law signed by Governor Josh Green in May. The legislation increases taxes on hotel rooms and vacation rentals and also creates a new levy on cruise passengers. 

Under the new regulation, cruise travelers would be charged an 11 percent tax on their fare, prorated based on the number of days their ship spends in Hawaii. AP News reported that the Aloha State’s individual counties are also authorized to add an additional three percent surcharge, potentially raising the total to 14 percent of a passenger’s prorated cruise fare.

State officials estimate the measure would generate nearly $100 million a year to help pay for shoreline erosion, wildfire response and other climate-related challenges.

CLIA sued to block the cruise portion of the law, saying the tax amounts to an unconstitutional charge on ships for entering Hawaii ports. The group also said the new levy would make Hawaii cruises more expensive, jeopardizing the state's tourism economy.

U.S. District Judge Jill A. Otake ruled in the state's favor last week, allowing the tax to move forward. CLIA appealed that decision to the 9th Circuit Court of Appeals, and the U.S. government also appealed.

The appeals court granted an injunction, stopping the cruise tax from being enforced until the pending legal actions are resolved.

Hawaii officials said they expect the law to ultimately be upheld. “We remain confident that Act 96 is lawful and will be vindicated when the appeal is heard on the merits,” Toni Schwartz, a spokesperson for the Hawaii attorney general’s office, said in an email to AP News.

Schwartz said the court’s decision only pauses the law. “The order temporarily halts enforcement of the law on cruise ships while the appeals process moves forward,” her email noted.

The lawsuit applies only to the cruise ship portion of the law. The higher taxes on hotel and vacation rental stays are not being challenged and remain in effect.

For now, cruise passengers sailing to Hawaii in 2026 will not be charged the new climate tax while the legal fight continues.
