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 ‘Neutrality’ step of Airport Carbon Accreditation requires neutralising remaining direct carbon emissions by offsetting.

How to achieve it?

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

  • Fulfil all requirements of ‘Mapping’, ‘Reduction’ and ‘Optimisation’
  • Offset its remaining Scope 1 and 2 carbon emissions (GHG Protocol) to show its commitment to achieving carbon neutral operations for all direct emissions and indirect emissions over which the airport has control, using internationally recognised offsets.

More information
Carbon neutrality is when the net carbon dioxide emissions over an entire year is zero (i.e. the airport absorbs the same amount of carbon dioxide as it produces). Achieving carbon neutrality for an airport is in almost all cases impossible without external help. For this reason, airports, among many other industries, look to carbon offsetting as the final part of the solution. Carbon offsetting is providing funds or resources to other projects that reduce carbon dioxide so as to make up for the emissions that one is not able to eliminate. For example, an airport could pay for a wind energy facility that replaces a coal-fired power-plant.

Airport Carbon Accreditation permits the use of the following internationally recognised offset instruments.

  • Certified Emission Reductions (CER)
  • Emissions Reduction Units (ERU)
  • Proprietary Verified Emission Reductions (VER)
  • European Union Allowance (EUA)
