Airports Council International, Greenport ’99 conference and exhibition – thinking green – strategies for balanced airport development in the next century, Amsterdam, The Netherlands 21–23 April, 1999

Airports Council International (ACI), ‘The Voice of the World’s Airports', is the only professional airport association in the world. ACI was formed in 1991 when the Airport Operator’s Council International (AOCI), the International Civil Airports Association (ICAA), and the Airport Associations Co-ordinating Council (AACC) merged to represent the world’s airports. ACI is based in Geneva, Switzerland with geographical regions in Africa, Asia, Europe, Latin America/Caribbean, North America, and the Pacific. Currently, ACIs membership consists of 528 members operating 1300 airports in more than 160 countries. ‘Greenport ’99’, the first conference of its kind, brought together organisations from around the world to discuss the future of airport development and its impact on the environment in the 21st century.
