Committed to
carbon reduction

Airport Carbon Accreditation recognises and accredits the efforts of airports to manage and reduce their carbon emissions. There are four levels of certification: 'Mapping', 'Reduction', 'Optimisation' & 'Neutrality'.


What is it?
The ‘Mapping’ step of Airport Carbon Accreditation requires carbon footprint measurement.

How to achieve it?

To achieve this level of accreditation, an airport has to:

  • Determine its ‘operational boundary’ and the emissions sources within that boundary which are Scope 1 and Scope 2 sources, as defined by the Greenhouse Gas Protocol
  • Collect data and calculate the annual carbon emissions for the previous year for those sources
  • Compile a carbon footprint report
  • Engage an independent third party to verify the report before submission, to ensure that the carbon footprint calculation is in accordance with ISO14064 and accreditation requirements.
More information
An airport must understand how much carbon it emits every year and from which activities and operations in order to plan how to limit these emissions. Therefore, as a first step, an airport needs to measure its carbon emissions, also known as its carbon footprint. An airport can measure its footprint itself, assisted by the accreditation guidance or get support from one of a number of specialist companies.
