The first-of-its-kind “Green Fee” will produce $100 million a year from tourism to fight climate change disasters.

Hawaii Governor Josh Green said the tax "ensures that visitors who come to Hawai'i are making an investment in Hawai'i's future."

In a landmark move, Hawaii has become the first U.S. state to implement a climate impact fee, introducing a new tax on tourists to support environmental initiatives. Announced on Tuesday, the fee is designed to fund climate change resiliency efforts and preserve the islands’ natural resources.
