The Global Cleantech Cluster Association (GCCA) is a non-profit association, headquartered in Atlanta, Georgia, U.S., that creates conduits for companies to harness the tremendous benefits of international cleantech cluster collaboration in an efficient, affordable, and structured way. Global Cleantech provides a gateway for established and emerging cleantech companies to gain exposure to potential investors, new markets, influential networks, innovative technologies and best practices.

Currently, the GCCA is a partnership of the top 50 cleantech clusters globally, representing over 4000 cleantech companies. 

In June, 2011, the GreenTech Exchange of British Columbia, Canada accepted the invitation from GCCA and became a member of this global organization. Since becoming a member, GreenTech Exchange has consistently been one of the top five most viewed clusters among GCCA members.
