Earn Airport Carbon Accreditation with a clear preparation plan
We bring airport-specific carbon expertise to the full ACA journey, from understanding your footprint to preparing for verification.
Airport carbon expertise, built into the process
We bring the airport knowledge and ACA experience needed to spot gaps early and build a programme that stands up to audits.
Built around ACA requirements
We work to the methodology, documentation and evidence requirements specific to Airport Carbon Accreditation.
Experience from the verifier side
Infinite was an Approved Verifier under Airport Carbon Accreditation in 2018, giving us first-hand understanding of what evidence is needed.
Beyond the airport boundary
Airport emissions can come from airlines, ground handlers and other third parties. We bring this data together and build a stronger case for ACA.
Carbon expertise beyond ACA
We bring wider carbon management experience to your ACA programme, helping you strengthen the airport’s broader climate goals.
ACA challenges we help airports overcome
Airport carbon programmes involve complex data and multiple stakeholders. We help bring these together for a smoother path through ACA.
Airport emissions sit across operations and third-party stakeholders. We help map the sources and build a complete carbon footprint.
Airlines, ground handlers, concessionaires and other stakeholders all contribute to the carbon footprint. We help coordinate the information needed to build a consistent programme.
Missing data or weak evidence can hold up accreditation. We identify the gaps early and prepare the data needed for verification
How we move from airport carbon mapping to accreditation
We take you from understanding your carbon footprint to building the evidence required for your ACA targets.
We identify relevant emissions sources across the airport and establish the carbon footprint required for your target level.
We assess your current position and define the targets and actions needed to progress.
We develop the reduction pathway and measures needed to support your accreditation goals.
Airlines, ground handlers and concessionaires all contribute to the footprint. We help bring their data together.
We compile the carbon data, supporting documents and records required for independent verification.
What you receive from an ACA engagement
A documented airport carbon footprint aligned with the requirements of your chosen ACA level.
Defined emissions targets, reduction measures and a carbon management plan to guide progress.
The documentation, stakeholder evidence and verification support needed to progress through ACA.
A practical pathway for maintaining or progressing to the next ACA level.
ACA expertise, built for the aviation industry
We understand the emissions, operations and stakeholders that make airport carbon management different, and tailor the ACA pathway accordingly.
Straight answers on airport decarbonization and ACA
Start with what airport operators ask most about levels and the certification process, then bring us your airport's details.
ACA is a global carbon management certification program specifically for airports, administered by ACI, that recognizes airports' efforts to measure, manage and reduce their carbon emissions across defined accreditation levels.
ACA has multiple levels, ranging from Mapping (measuring emissions) through Reduction, Optimisation, Neutrality, and Transformation, reflecting progressively more advanced carbon management and stakeholder engagement.
Airport operators of any size can apply for ACA, with the requirements and scope of emissions covered (airport operations, and increasingly Scope 3 partners) depending on the level being pursued.
The process includes building a carbon footprint for airport operations, developing a carbon management plan, engaging stakeholders at higher levels, and undergoing independent verification before accreditation is awarded.
We help airports build their carbon inventory, develop the required carbon management documentation, prepare for independent verification, and plan progression to higher accreditation levels.
