For the Sierra Club, the key to more than a century of successful environmental activism is people - passionate, committed people like you who are actively involved in our work and who provide financial support.
Join us! Become a Sierra Club member, and take the first step toward being part of a global team to protect our land, air and water. Then learn how you can get involved as a volunteer with your local Sierra Club group or our state chapter.
If you’re already a member or simply want to support the work of the Sierra Club in Illinois, you can donate online. Gifts made through our website will go directly to the Illinois Chapter. You can make a one-time donation or set up a monthly gift.
Thank you for joining and supporting the IL Sierra Club!
