Welcome to the November edition of the Illinois Green Policy Update. We're incredibly excited to share some important updates about Illinois' recent climate policy achievement and more!



Illinois Just Passed the Clean and Reliable Grid Act: Here’s what the Building Industry Needs to Know 

A few weeks ago, Illinois legislators took major action to address rising energy costs and add clean energy to the grid through the Clean and Reliable Grid Act (CRGA). Over the last year this issue rose in prominence as residents across the state have seen their energy bills rise due to  rising capacity costs and increased  demand from data centers

 

The 1,000+ page bill focuses on addressing these challenges in a number of ways, focusing on clean energy generation and grid capacity solutions, while also creating new opportunities for green buildings across the state. We put together a summary of these key components!

What does Chicago’s Latest Budget Proposal Mean for Green Buildings? 

Recently, Mayor Brandon Johnson released his 2026 Budget Proposal for the City of Chicago. Here are some key elements that industry professionals should be aware of: 

 

  • The Department of Environment would receive a major increase in budget and responsibility. The proposal returns the power to the Department of Environment by transitioning existing inspection, enforcement, and planning roles from other departments to the Department of Environment and allocates over $52 million to carry out these responsibilities.  
  • The Department of Planning and Development is set to lose a significant amount of funding due to the expiration of federal grant funding.  
  • The Department of Buildings would receive a minor budget cut and prioritize updating their permitting and inspection system. 

 

The Mayor, City Council, and key stakeholders will be negotiating the budget through the rest of the year. We’ll be tracking any changes impacting buildings and decarbonization through this process. Find the current proposal here

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.
