The threat of climate change, the global economic crisis and the resulting changes in the structure of the European aviation market have led to a renewed focus on efficiency and performance for Europe’s airports. In October 2008, ACI EUROPE and EUROCONTROL signed a collaboration to increase operational efficiencies at European airports.

This collaboration revolved around the implementation of an innovative operating practice called Airport Collaborative Decision-Making (ACDM) which allows airports into the Air Traffic Management network and vice versa.
