The Airport Carbon Accreditation (ACA) Program is the only internationally endorsed standard that independently evaluates and recognizes airports’ efforts to manage and reduce their CO2 emissions.
Participating airports can be certified at different levels of accreditation:
Level 1: MAPPING Footprint measurement
Level 2: REDUCTION Carbon management towards a reduced carbon footprint
Level 3: OPTIMIZATION Third party engagement in carbon footprint reduction
Level 3+: NEUTRALITY Carbon neutrality for direct emissions by offsetting
Level 4: TRANSFORMATION Transforming airport operations and those of its business partners to achieve absolute emissions reductions
Level 4+: TRANSITION Compensation for residual emissions with reliable offsets
Level 5 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
