What is Airport Carbon Accreditation?

Airport Carbon Accreditation is the only institutionally-endorsed, global carbon management certification programme for airports. It independently assesses and recognises the efforts of airports to manage and reduce their carbon emissions through 7 levels of certification: ‘Mapping’, ‘Reduction’, ‘Optimisation’, ‘Neutrality’, ‘Transformation’, ‘Transition’ and ‘Level 5’.

Level 1: Mapping

Footprint measurement

Determine emissions sources within the operational boundary of the airport company.
Calculate the annual carbon emissions.
Compile a carbon footprint report.

Level 2: Reduction

Carbon management towards a reduced carbon footprint

All of the above plus:
Provide evidence of effective carbon management procedures.
Show quantified emissions reductions.

Level 3: Optimisation

Third party engagement in carbon footprint reduction

All of the above plus:
Widen the scope of carbon footprint to include third party emissions.
Engage third parties at and around the airport.

Level 3+: Neutrality

Carbon neutrality for direct emissions by offsetting

All of the above plus:
Offset remaining emissions for all emissions over which the airport has control with high quality carbon credits.

Level 4: Transformation

Transforming airport operations and those of its business partners to achieve absolute emissions reductions

Define a long-term carbon management strategy oriented towards absolute emissions reductions, aligned with the objectives of the Paris Agreement. Demonstrate evidence of actively driving third parties towards delivering emissions reductions.

Level 4+: Transition

Compensation for residual emissions with reliable offsets

All of the above plus:
Offset the residual carbon emissions over which the airport has control, using internationally recognised offsets.

Level 5

Level 5 is the topmost level in Airport Carbon Accreditation programme

Maintaining a Net Zero balance on scopes 1 and 2 and actively addressing Scope 3 emissions, strengthening approach to 3rd party engagement, offset removals for residual emissions
