Airport Carbon Accreditation (ACA)

Providing verification services for all levels of accreditation

Airport Carbon Accreditation (ACA)We assist airports in Australia and the Asia Pacific region with Airport Carbon Accreditation (ACA) verification services. Our ACA verifier is the first in Australia to verify airports under the ACA Program

About the ACA

The Airport Council International (ACI), the only global association of airport operators, is behind the ACA program. The ACA gives aviation its own carbon emissions management program. This is the only such institutionally endorsed certification for airports. It provides a tailored yet flexible framework for a greenhouse gas intensive industry using internationally approved methodologies.

The ACA program comprises four stages or levels. An airport may choose to participate in the program at any level, provided it meets entry requirements for that level. Put simply, the ACA program involves measuring then managing an airport’s impact on the environment. The end goal is carbon neutrality, or net zero emissions.

Levels of carbon accreditation

The ACA is designed for airports of all sizes in any area. There are 4 levels of accreditation.

Level 1: Mapping

Mapping requires measuring and verifying an airport’s carbon footprint. Mapping incorporates Scope 1 and Scope 2 level emissions.

Verification component summary

An independent third party must verify the greenhouse gas calculations. See all of our accreditations.

Level 2: Reduction

Reduction requires the airport to act on managing carbon emissions effectively, generally with proven results across a 3-year period. Attainment of this level requires demonstrated effective carbon management procedures to achieve emission reduction targets.

Verification component summary

The airport’s greenhouse gas calculations, carbon management plan, reduction targets and management strategies must be verified for accreditation at Level 2.

Level 3: Optimisation

Optimisation requires an expanded reduction strategy that incorporates third party providers and suppliers, or Scope 3 emissions. Achievement at this level requires an airport to account for the Landing and Take-Off (LTO) cycle of in and out-bound aircrafts.

Verification component summary

The airport’s greenhouse gas calculations, carbon management plan, reduction targets, management strategies and stakeholder consultation plans with, but not limited to, airport tenants and airlines must be verified for accreditation at Level 3. At this level the airport must also demonstrated verifiable Scope 3 emission calculations.

Level 3+: Neutrality

Carbon neutrality involves offsetting emissions that cannot be eliminated through reduction and optimisation strategies. In essence, achievement at this level is the combination of Levels 1, 2 and 3, plus offsetting residual emissions attributable to the airport.

Verification component summary

We will verify all of the requirements of Levels 1, 2 and 3, including the offsets (or carbon credits) used toward the airport’s carbon neutrality plan.
