Airport Carbon Accreditation

Airport Carbon Accreditation (ACA)

We provide accreditation verifications services for all levels in the Airport Carbon Accreditation Program, with our expert staff authorized by WSP (Airport Carbon Accreditation Program Manager).

The ACA is designed for airports of all sizes in any area.

What Is Airport Carbon Accreditation?

The Airport Carbon Accreditation Program is a global carbon management program for airports. The program independently evaluate and recognizes airports' efforts at managing and reducing CO² emissions. ACA is managed by Airport Council International (ACI), global association of airport operators. Airport Carbon Accreditation Program is an internationally certified certification for airports, providing a special and flexible framework using appropriate methodologies for calculating and verifying greenhouse gases.

Applications are made through the ACA website and the verification process is carried out through the Authorized Authority/Verifier through the ACA website.

What Are The Benefits Of Airports?

  • Airports report their emission reductions in a real and verified way by monitoring the aviation-related emissions methodologically due to the program.
  • Airports identify priority areas for reducing emissions and gain a systematic for data collection and verification.
  • With emission reduction efforts, the airport and third-party organizations (ground services, maintenance organizations etc.) effectively monitor their activities and achieve operational / cost efficiency with improved emission performance.
  • Airports get great respect as part of their social responsibility projects.
  • Improved dialogue is established between airport corporation and different organizations for greenhouse gas activities.

Airport Carbon Accreditation Levels 1,2,3 and 3+

The program consists of four levels. Airports can choose to participate in the program at any level, provided they meet the entry requirements. The ACA program includes measuring and managing an airports' environmental impact. The ultimate goal is carbon neutrality or net zero emissions. The levels and requirements for the program are outlined below.

Level 1 (Mapping)

It is the basic level of the Program.

Scope 1 and Scope 2 carbon footprints are identified and developed.

Policy commitment is made to reduce emissions.

Level 2 (Reduction)

It can be applied provided that all first accreditation conditions of level 1 (mapping)   are met.

It needs to show Scope 1 and 2 emission reductions compared to the three-year average by effectively managing carbon emissions.

It is necessary to establish the targets of reducing emissions and develop the Carbon Management Plan accordingly.

Level 3 (Optimisation)

It can be applied provided that all first accreditation conditions of level 2 (reduction) are met.

The carbon footprint needs to be prepared to include scope 3 emissions.

The Stakeholder Engagement Plan needs to be developed.

Level 3+ (Neutrality)

It is the highest level of the program.

It can be applied if all first accreditation conditions of level 3 (optimisation)   are met.

It needs the residual emissions (remaining emissions after all possible reductions made) to be offset.
