The Sierra Club of Hawaiʻi is committed to advancing climate solutions, acting for justice, getting outdoors, and protecting Hawai‘i’s lands, water, air, and wildlife. Through our tried and true grassroots advocacy, long-standing outings program, and public interest litigation we connect people to the things they care about in nature and help them better defend the natural resources they depend on. We work on both statewide and county-based issues, activating our 27,000+ members and supporters to get involved on issues they care about through our groups on Hawaiʻi Island, Maui, Oʻahu, and Kauaʻi.
