Green Certifications


The CDA boasts 12 certifications at O’Hare and Midway International Airports that have earned 3rd party recognition for sustainable design and construction. These voluntary certifications are developed and maintained by governing bodies that ensure their standard is consistent with current research and industry best practice. Achievement of any certification proves the commitment to good environmental and social practices.

The LEED certification, bestowed by the U.S. Green Building Council (USGBC), indicates that a structure has achieved a requisite level of sustainability, resource efficiency, energy efficiency and environmental quality. Projects are awarded points for incorporating sustainable technologies and USGBC aims to help building owners and operators be environmentally responsible and use resources efficiently. O’Hare and Midway are currently home to 11 LEED certified buildings.
