Why Support the Sierra Club of Hawaii?

We're the only local environmental organization that comprehensively:
  • interviews and endorses candidates for federal, state, and county offices;
  • leads the way on recycling, energy, and coastal protection issues;
  • has a lobbyist at the State Capitol;
  • holds local outings on a weekly basis that are free and open to the public;
  • takes youth into nature through hiking and camping events;
  • highlights violations degrading the environment; and
  • has worked to protect Hawai`i's environment for over forty years.


We're too Good for Tax Donations!

The Sierra Club is a 501(c)(4) non-profit organization under the regulations of the Internal Revenue Service. As a result of our effective work for new environmental policies, contributions are not tax deductible. Every dollar of your contribution, however, stays right here in Hawaii.
