Illinois

Illinois passed the historic Climate and Equitable Jobs Act (CEJA) in 2021, putting the state on the pathway to 100% clean energy by 2050. By 2024, Illinois cut emissions 20% from 2005 levels, but meeting the state’s 2025 climate target would require an additional 39% cut from present-day emissions. The state is a key hub for national crude oil and natural gas distribution, although in-state electricity generation from coal is declining in response to stricter emissions regulations and economic pressures.

Enacted	Residential Energy Codes Empty column The statewide energy code for residential construction is 2021 IECC with amendments. Establishing Policies Illinois State Energy Code (2023)	Buildings and Efficiency	Building Codes	2023
Enacted	Commercial Energy Codes Empty column The statewide energy code for commercial building construction is 2021 IECC with amendments. Establishing Policies Illinois State Energy Code (2023)	Buildings and Efficiency	Building Codes	2023
Enacted	Stretch Building Energy Codes Empty column The Illinois Capital Development Board approved the Illinois Residential Stretch Code on April 9, 2024. The Code will be available for municipalities to adopt by October 31, 2024. Establishing Policies SB 2408 (2021) Illinois Residential Stretch Code (2024)	Buildings and Efficiency	Building Codes	2024
Not Enacted	Appliance Standards Empty column Appliance standards set minimum energy and water conservation requirements for appliances and equipment.	Buildings and Efficiency	Building Standards
Not Enacted	Building Performance Standards Empty column Building performance standards establish energy and/or greenhouse gas performance targets for existing buildings in a state. These targets increase in stringency over time, leading to efficiency improvements in buildings to conserve energy and reduce emissions.	Buildings and Efficiency	Building Standards
Not Enacted	Clean Heat Standards Empty column Clean heat standards establish a performance standard requiring heat providers to deliver a gradually-increasing percentage of low-emission heating services to customers.	Buildings and Efficiency	Building Standards
Enacted	Energy Efficiency Resource Standards (EERS) Empty column Electric utilities are required to achieve cumulative persisting annual savings of 21.5% by 2030 for utilities serving more than 3,000,000 retail customers, and cumulative persisting annual savings of 16% by 2030 for utilities serving between 500,000 and 3,000,000 retail customers. Savings are relative to average consumption over 2014-2016. Gas utilities are required to achieve annual energy savings of 1.5% each year.

Enacted	Property Assessed Clean Energy (PACE) Empty column Illinois has enacted commercial PACE-enabling legislation and has active programs. Establishing Policies HB 2831 (2017)	Buildings and Efficiency	Building Efficiency	2017
Partially Enacted	Weatherization Funding Empty column The State Policy Opportunity Tracker (SPOT) breaks clean energy policies down into “components”, which are binary questions to evaluate policy quality. Higher quality policies have more of their SPOT components fulfilled.
