About Us

The Sierra Club of Hawai‘i is one of the oldest and most effective grassroots environmental organizations in the islands. Founded in 1968, we currently have more than 20,000 members and supporters volunteering to help people better explore, enjoy, and protect Hawaiʻi’s unique environment and wildlife. Through outings, litigation, and advocacy we are able to connect people to the things they care about in nature and help them better defend the natural resources they depend upon.

The Hawaiʻi Chapter is made up of four regional groups with appointed representatives on the Executive Committee, seven elected chapter leaders and two additional appointed volunteers, as needed.  We also have seven paid staff, including Group Managers on Oʻahu and Maui.

What We Do

The climate is changing faster than ever and the Sierra Club of Hawaiʻi is laser focused on adapting to the impacts we are already seeing and mitigating what future impacts we can. This means looking holistically at the climate change issues at hand and implementing innovative ideas to protect our islands and people from the worst effects of climate change. 

Water Security
Water is vital for all life. However, climate change brings with it threats to our freshwater availability—increased droughts, storm activity, and rising seas. The Sierra Club of Hawaiʻi is advocating for the return of waters to public streams previous monopolized by sugar barons and corporations, for the removal of water diversions and better management of watersheds, and for the protection of our aquifers from pollution. 

Carbon Free Hawaiʻi
Hawaiʻi has committed to being carbon neutral by 2045 and the Sierra Club of Hawaiʻi is dedicated to making sure that happens. We are working to ramp down our islands’ reliance on dirty fossil fuels and completely cut our coal dependence, increase our clean energy production, all the while planting more trees to sequester the carbon already in the atmosphere.

Land Stewardship
Nature-based solutions provide effective and less-intrusive mitigation and adaptation to climate change. The Sierra Club of Hawaiʻi supports projects that return nature to nature and benefit society. This means pushing for local sustainable agriculture, like permaculture and native food systems, reforestation projects that improve soil health, and preserving special open places and nearshore waters.

We value diversity and promote environmental justice as we work to fulfill our mission to explore, enjoy, and protect the Hawaiian Islands and its local culture.

Thanks to the support of our members, people in Hawaiʻi are better connected to their environment and their public policymakers. Our advocacy has accomplished a number of longstanding goals including creating a beverage container recycling program (HI-5), establishing Hawaiʻi’s 100% renewable energy goal, mandating solar hot water heater on all new homes, and securing funding to preserve and protect natural resources. Our outdoor education efforts have protected public access to trails and beaches and restored hundreds of trails on public and private land.
