Annual Performance Review

We are pleased to publish these Annual Performance Review Reports about the Emissions Reduction Market System (ERMS) in Illinois. The ERMS is an innovative, market-based approach for reducing emissions of volatile organic materials that contribute to ozone nonattainment. These reports document the progress that results from implementation of this new market system and provides an analytical framework that serves as a platform for future evaluation of key trends and patterns that may be important for us to monitor.
