Citing the growing impacts of global warming, Hawaii Gov. Josh Green said Monday that he will jumpstart efforts to enact a climate impact fee on tourists. The $25 charge would be levied on visitors when they stay at an island hotel or short-term rental. Green called it a “modest” fee that was “far less than the resort fees or other taxes visitors have paid for years.” He estimated it would generate more than $68 million every year for the state’s use.
