We're Building Power for People and the Environment.

The Illinois Environmental Council (IEC) was created in 1975 to ensure that the collective voice of Illinois’ environmental community was amplified in public policy debates and legislative action. Today, IEC is proud to lead the strongest environmental movement in Illinois' history.

Representing over 130 environmental organizations operating in Illinois, IEC carries out our mission to advance equitable public policies that create healthy environments across Illinois through collaboration, building power, and advocacy.
