IEC Affiliates

We rely on our affiliates
to identify issues facing our environment

Since our founding in 1975 by a group of dedicated grassroots environmentalists, IEC has advanced public policies that protect the environment in Illinois.

IEC builds the power of the environmental community by convening and advocating on behalf of more than 100 organizations working to protect the Illinois environment. Non-profit organizations are welcome to apply for membership at any time throughout the year.
