Airport Carbon Accreditation
We are fully accredited verifiers for the Airport Carbon Accreditation application process.
The Airport Carbon Accreditation Scheme is the only voluntary and independent carbon management and reduction programme designed specifically for airports.
It’s estimated that aviation contributes up to 2% of global man-made CO2 emissions each year and that airport activities account for 5% of total aviation emissions.

What is Airport Carbon Accreditation?
Airport Carbon Accreditation (ACA) is the carbon management certification standard for airports. Airport efforts to manage and reduce their carbon emissions are recognised with four levels of award:
- Mapping: Carbon footprint measurement. This award determines the emissions sources within the airport company’s operational boundaries, calculates the annual carbon emissions, compiles a carbon footprint report, and engages an independent third party to verify the report.
- Neutrality: Carbon neutrality for direct emissions by offsetting. Airport companies must offset remaining emissions to achieve carbon neutral operations for all emissions over which the airport has control
- Reduction: Carbon management towards a reduced carbon footprint. To receive this award, airport companies must provide evidence of effective carbon management procedures and show that reduction targets have been achieved.
- Optimisation: Third party engagement in carbon footprint reduction. Airport companies in receipt of this award have widened the scope of their carbon footprint to include third party emissions, as well as engaging third parties in and around the airport.
ACA is overseen by an Independent Advisory Board. The scheme supports the global airport community in reducing its carbon footprint, showcasing its carbon reduction achievements and sharing its knowledge and best practice.
There are currently 237 accredited airports across the globe accredited at one of the 4 levels;
Level 1 – Carbon footprint and policy
Level 2 – Emissions reduction target, carbon management plan & annual reductions
Level 3 – Engagement of 3rd parties & measurement of their emissions
Level 3+ – Offsetting own scope 1 & 2 emissions
As part of the Airport Carbon Accreditation application process, each airport’s carbon footprint must be independently verified before its full review by the programme Administrator. This verification process assures that the emissions calculations are reliable and emissions reductions are real. EIC are a listed, approved verifier.
