Our number one goal is to ensure a healthy environment for people, plants, and animals.
From the shores of Lake Michigan to the forests of the Shawnee, Illinois is a state rich in natural beauty. It's our job to protect these places. Sierra Club Illinois's priorities reflect the diversity of our state's natural resources and our commitment to the health of our communities. Here you can find information about our campaigns on conservation, energy issues, clean water, and transportation, as well as the work we do to elect leaders that will support our legislative priorities.
