Comparison: State vs. Federal
• Rules. Applicable sources must comply with the federal greenhouse gas (GHG) reporting program under 40 CFR 98. Illinois has no additional mandatory GHG reporting, but voluntary reporting is encouraged.
Illinois has developed statutes and issued Executive Orders (EOs) to address GHG emissions in order to meet state-established GHG emissions reduction targets. Applicable sources emitting above federal thresholds for GHG emissions must comply with appropriate construction and operating permit requirements. In addition, the state is working with other states to implement regional programs to monitor and control GHG emissions.
• Administration and enforcement. The Illinois Environmental Protection Agency's Bureau of Air administers the state's GHG management programs to address GHG emissions and coordinates with other states to assist in the implementation of regional climate change initiatives.
REPORTING GHG EMISSIONS
At this time Illinois has no mandatory GHG reporting requirements beyond the federal mandatory GHG reporting rule. See the national section GHG MANAGEMENT for more information on mandatory GHG reporting.
