The Illinois Green Business Association (IGBA) is a 501(c)3 non-profit organization that assists businesses in reducing their ecological foot-print through green certification.  IGBA looks at a business’ current environmental performance in nine areas of certification and works with the business owner to discover what applies to them and what fits in with their business' culture, providing educational resources and support along the way.

The IGBA Technical Advisory Groups are standing committees of the IGBA Board of Directors, consistent with Article III of the IGBA Bylaws. The Technical Advisory Groups (TAG’s) will review, revise, make additions, and enhance the IGBA green business certification standards. The Technical Advisory Groups report directly to the IGBA Certification Steering Committee. The Sustainable Transit Technical Advisory Group (TAG) will review the IGBA green business checklist standards and make additions, and revisions to all standards in the transportation section based on local and national trends affecting businesses.
