The Maine Chapter, which celebrated its 30th year in 2023, is a volunteer-run, grassroots organization, working with volunteers like you to:

  • Protect Maine’s wilderness heritage
  • Fight global warming & promote smart growth
  • Safeguard Maine’s clean water and coastline
  • Promote clean air and energy efficiency
  • Hold public officials accountable
  • Support pro-environment candidates for public office

 Please explore our website to find out what we are working on and how you can get involved to protect and enjoy Maine's incredibly special natural environment!

We urge you to become a member or renew your membership today. We also invite you to join one of our teams and to volunteer in a variety of ways. Be sure to check out our calendar to participate in our hikes, walks, films and other community events. We always welcome your donations which are critical in supporting our important work.

Thank you for all that you do to protect Maine's environment.
