The Airport Carbon Accreditation programme has been a successful vehicle for getting airports to measure and mitigate their emissions. Currently, the tool is being used by nearly 100 airports in Europe, Asia-Pacific and Africa - serving a decent chunk of international passengers.

The programme is a very in-depth analysis of an airport's CO2 emissions and it requires either dedicated airport experts, or the services of external suppliers to complete. It enables airports to identify from where their emissions are being produced and to work on cutting CO2 emissions.

As Airports Council International have been explaining today at the ACI World Annual General Assembly in Seoul, for small and medium-sized airports which don't have the expertise in-house, ACI has developed, with Transport Canada, the Airport Carbon Emissions Reduction Tool (ACERT for short). This simple tool enables all airports to start measuring their carbon emissions in three categories:

  1. those emissions created by the airport itself though on-airport power supply, vehicles and so on;
  2. those emissions used by the airport company, but generated off-site - mostly from electricity suppliers; and
  3. third-party emissions, which are the largest source and come from aircraft operations and ground handling, among other sources.

Importantly, ACERT can be used to start the process of measuring and then reducing emissions - and is also compatible with the Airport Carbon Accreditation programme if the airport wants to join that too.
