Level 3+ Neutrality

How to achieve?

To achieve this level of accreditation, an airport must:

  • Meet all the requirements of ‘Mapping’, ‘Reduction’ and ‘Optimization’
  • Offset the remaining Scope 1 and 2 carbon emissions, as well as emissions from staff business travel, using internationally accepted offsets

Carbon neutrality is achieved when the remaining airport emissions are offset by purchasing carbon credits. Carbon offsetting funds other projects that reduce carbon dioxide to compensate for emissions that cannot be completely eliminated by the airport. For example, an airport might pay for a wind power plant to replace a coal-fired power plant.

Airport Carbon Accreditation has developed a bespoke Offsetting Handbook based on a study conducted by environmental consultancy Ecofys. Airports that decide to offset their remaining emissions are encouraged to consult this comprehensive guide to choosing reliable carbon credits.

One of the key requirements of Level 3+ ‘Objectivity’ is that airports continue with balancing only after reducing their emissions as much as possible. To help airports assess whether they are already using their full available emission reduction potential, Airport Carbon Accreditation provides specific Guidance on Emissions Reduction Before Balancing.

Airport Carbon Accreditation supports UNFCCC’s ‘Climate Neutral Now’ campaign.
