Illinois Green Policy Update: October 2025

Ryan Wilmington • October 8, 2025

Welcome to the October edition of the Illinois Green Policy Update. We're excited to share several updates about how Illinois Green and our membership can empower resilient communities, support strong energy policy, and advance green building policies across the state.



Announcing the Illinois Clean Building Commitment

I’m incredibly proud to announce Illinois Green’s latest initiative: The Illinois Clean Building Commitment!

 

This effort aims to help local communities protect residents from rising energy costs, lower public health risks, create green jobs, and set themselves up for a resilient future.

 

To do so, we want to reach local policymakers across the state and let them know how to bring green buildings to their community. By providing education on green buildings and technology, sharing existing energy incentives and opportunities, and creating a pathway for policy action, we will help local leaders across the state become green building champions.

 

Here's how professionals can support this work:

  • Share the Commitment with your local representatives! Hearing from industry voices is crucial — especially if you have any connections.
  • Help us demonstrate the value of green buildings by sharing any project examples, case studies, fact sheets, or other valuable information.
  • Know about any other green resources or tools for communities? Let us know!

State Lawmakers to Revisit Clean Grid Legislation in October

Illinois state legislators are working to pass the Clean and Reliable Grid Affordability Act, a large scale energy package intended to protect consumers from increased demand from data centers and build resilience by improving grid connections and more. 

Some key features of the legislation include:

•  Removing barriers that make it difficult and slow to connect new clean power to the grid,
•  Funding both large-scale battery storage and ‘
virtual power plants’,
•  Increasing utility spending on energy efficiency programs,
•  Require utilities to share energy data for entire buildings, allowing buildings to understand their energy use and create savings plans,

Support a Clean, Reliable, and Affordable Grid!

Support a Strong Energy Code Across Illinois

The latest energy code is ready for Illinois to adopt, but we need the help of building industry leaders to let legislators know why a strong code is important!



This new energy code would save $133-$309 for the average Illinois household in a new home, depending on their location in IL and gives designers more flexible options for compliance to support affordable, abundant housing development. Some Illinois amendments also will make it cheaper for businesses to electrify by adding limited electric readiness requirements and fuel debiasing language.

 

The 2024 IECC was developed with input from collaboration from stakeholders across the industry and the Illinois Capital Development Board recommended its adoption after an open input process. 

 

Learn more about the code and tell key legislators that the building industry supports strong codes!

he mission of the Illinois Green Schools Project (IGSP)—our year-long school sustainability action and recognition program--is to empower educators, school administrators, students, and school communities to create healthy, sustainable learning environments. This work requires passion, collaboration, and informed support, and as an IGSP program coordinator, I’m always on the lookout for opportunities that help schools build the knowledge and connections needed to drive meaningful, lasting change in their buildings and districts. The Green Schools Conference has long been one of the most impactful gatherings in this space. Its focus on the intersection of environmental health, sustainability, and education makes it a uniquely valuable event for anyone working to make schools healthier and greener places for students to learn and grow. From educators, administrators, and district representatives to facilities managers, students, and community organizations, the Green Schools Conference is a powerful space to learn, collaborate, and fuel your next big idea. This year’s conference promises a rich lineup of workshops, education sessions, and networking and recognition events that speak to the needs and realities of today’s school sustainability landscape. Districts across Illinois are navigating shrinking budgets, aging infrastructure, and a newly passed state-wide law requiring the inclusion of climate education in public school curriculum starting in 2026. Therefore, I’m particularly excited to see sessions on the agenda exploring climate action and resilience planning, opportunities to connect students to sustainability career pathways, and environmental literacy in classrooms. These conversations are essential as programs like the Illinois Green Schools Project continue evolving to support schools in setting goals, tracking progress, and engaging diverse communities in sustainability work. If you’re considering attending this year, I encourage you to take a look at the agenda and explore the sessions that could support your school or organization’s goals. You’ll find no shortage of practical insights, creative ideas, and meaningful connections. I know those who attend will come away with the same clarity, inspiration, and sense of comradery that have made past conferences so influential for myself and others in the Illinois school sustainability community.

At the start of 2025, I told our members that we can build a movement of green building advocates that can continue the progress made in Illinois for high-performance building, regardless of what happens in Washington D.C. Over the last year, you’ve proven me right. While elsewhere green building and clean energy goals have been put on pause, Illinois has continued the fight and won three huge victories that completely change the landscape for green buildings and clean energy.
