Business Sustainability

Want to Green Your Business?

DuPage County is committed to reducing its impact on the environment and so we encourage businesses to pursue sustainability certifications, awards, and other programs. This information is provided as a service to businesses and is updated intermittently or when changes are brought to our attention. Inclusion on this page is not an endorsement of any of these companies/certifications, nor has the County purposely excluded any parties that provide sustainability programs and/or certifications.

Sustainable DuPage

Cool DuPage in partnership with Choose DuPage created Sustainable DuPage in 2021 starting with a series of webinars that can be seen below. The program then expanded in 2023 with Choose DuPage partnering with the Smart Energy Design Assistance Center (SEDAC) to develop a Green Business Assessment. 

Green Business Assessment

The Green Business Assessment was created in a partnership between Choose DuPage and SEDAC to offer small to medium businesses a free assessment of their site that starts with a site visit then builds into a Green Action Plan, a custom report outlining where improvements can be made, and a platform to record the progress all for free. See this link for how to apply.

PACE - Property Assessed Clean Energy

Property Assessed Clean Energy financing is an innovative tool that provides low-cost, long-term funding for energy efficiency, renewable energy, water conservation projects in commercial buildings. Commercial property owners can obtain 100 percent upfront financing from private capital providers for up to 30 years for improvements such as HVAC, lighting and solar photovoltaic systems in both existing building and new construction projects. Funding is secured by a special assessment lien on the property and is repaid as a line item on the property tax bill.
