By Twyla Neely-Streit December 16, 2025
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.
By Ryan Wilmington December 15, 2025
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.

Our Initiatives


Green Building Education

The professionals that design, build, and operate buildings are important advocates for net zero, and need a reliable source for the latest trends and technologies. We deliver effective educational programs, convening diverse professional stakeholders.

Existing Buildings Programs

We believe that all communities deserve healthy, high performing buildings. Through our Building Energy Resource Hub and Illinois Green Schools Project initiatives, we provide the support to show all building types can be on the path to net zero.

Green Building Policy

We must remove barriers by providing information about the technical and policy roadblocks to net zero adoption. We amplify green building professional voices that impact green building policy and support the passage of major climate laws.

MEASURING OUR IMPACT

To combat climate change in Illinois, it's time we made net zero buildings feasible, affordable, and so commonplace that every building in Illinois by 2050 is net zero. Mainstreaming the technology and building methods, whether new or existing, will not be easy but no one is better positioned to make it happen than green building professionals.

Over the past six years my colleagues have grown to be my friends, and I learn something new about sustainability, life, and myself through everyone and every event I attend."
