For activities outside the direct control of the airport company, Airport Carbon Accreditation also takes account of collaborative engagement with stakeholders such as airlines, air traffic control, ground handlers and public transport, to help guide or influence their activities on the airport site to lower carbon emissions.
Recently announced collaborations include:
- A Memorandum of Understanding between ACI EUROPE and EUROCONTROL (Oct 2008 download). This involves the implementation of Airport-Collaborative Decision-Making (A-CDM) at 45 European airports by the end of 2009, allowing for a potential emissions reduction of 475,000 tons of CO₂.
- An agreement between ACI EUROPE, CANSO, EUROCONTROL and IATA on Continuous Descent Approach (CDA) (April 2009 download). CDA is an air traffic control operation which reduces fuel burn when aircraft come in to land, lowering carbon emissions. CDA is being rolled out at over 100 European airports between 2009 and 2013.
