Net zero is possible

AirCarbon is the software product that helps airports move faster and make more progress to quantify and reduce emissions from aviation.


Why airports?

The center of aviation

Airports are the center of aviation and therefore the natural entry point to quantify emissions while touching other actors in the value chain.


AirCarbon is a software product estimating scope 3 emissions of airports because these represent most emissions within aviation.

Common questions

What is AirCarbon and why does it exist?

AirCarbon is a product to enable the airport transport industry players in their common journey towards net-zero emissions.

On we strive to quantify emissions related to aircraft operations using traffic data and best practice emission factors, calculations and attribution methodology provided by the Airport Carbon Accreditation program.

All industries must decarbonize to survive and thrive for the long term. In 2023, aviation accounts for approximately 2-3% of global emissions. Improvements to modern aircraft engines have been made – making them cleaner, but these improvements do not offset the overall trend to travel more. This makes aviation one of the fastest growing industries in terms of emissions.

A growing portion of passengers care about emissions and it is likely that more stringent regulation will force the industry to decarbonize, or to pay for emissions. Companies who are on the forefront of carbon reduction and who have taken voluntary measures today will likely be better prepared for the future.

Most investments into decarbonization are long-term and long-term investment programs require data so that the right investments can be made, and that the effectiveness of those investments can be tracked. Within the aviation industry, decarbonization will be a collaborative effort as no stakeholder has incentives to do it alone.

AirCarbon exists to provide the industry with easily accessible data and workflows to facilitate decarbonization.

Initially, AirCarbon is geared towards airports as airports are the central nodes of the aviation industry where nearly all stakeholders meet or have some sort of interface to each other.

AirCarbon is created by Ardian – a private French investment house.

How does AirCarbon work and what emissions are displayed?

AirCarbon captures data on every commercial flight worldwide, around 100,000 flights per day. AirCarbon then combines this data with best-practice emissions calculation methodologies from the ACA to allocate emissions to specific airports.

According to the Greenhouse Gas Protocol (“GHG Protocol”) – a widely adopted standard to manage emissions, emissions from a company can be broken down into three categories, known as Scopes in the GHG Protocol.

  • Scope 1 – emissions that are directly controlled by the company i.e. service vehicles
  • Scope 2 – emissions that are caused indirectly by the company i.e. electricity and heat consumption
  • Scope 3 – emissions that are not produced by the company and are not the result of activities from assets owned or controlled by the company.

AirCarbon is focused on Scope 3 emissions from airports. Airports are at the center as they are the physical places where most of the aviation industry comes together. Scope 3 is the focus because these amount to more than 96% of the emissions from an airport on average. Longer term, the ambition is to cover all scope 3 emissions. AirCarbon Public currently contains:

  • Landing & Takeoff Cycle (“LTO”)
  • Aircraft taxi
  • Auxiliary Power Units (“APU”)

Where does the data in AirCarbon come from and how are emissions calculated?

Data in AirCarbon comes from multiple sources.

Emissions calculation in AirCarbon combine four sources:

  • Flight information from
  • Airports information from
  • Additional aircraft information from the FAA (US Federal Aviation Administration)
  • • Emissions factors from the Airport Carbon Accreditation ACERT tool

Using flight information, AirCarbon attributes the correct emission factors and quantities of Jet A fuel estimated by the ACA. For LTO cycles, AirCarbon aligns on the standard LTO cycle calculated by the ACA. For taxi, a standard 15-minute taxi time per flight is taken as hypothesis. For APU, a standard 10-minute APU-on time per flight is taken as a hypothesis. Emissions factors depend on engine type. As AirCarbon does not collect information granular enough on engine types, engine types for each aircraft type are inferred using the ACERT tool from the ACA.

Emissions are then allocated to each airport for each type of scope 3 emission.

Data processing is performed similarly across all airports on the publicly available AirCarbon application. However, if you notice any incoherence in the data shown on AirCarbon, you are welcome to contact us so that we can rectify it.

AirCarbon can also collect data directly from airports operational databases as part of the Premium plan of the product. This data is not shared publicly and remains available only to the customer airport. This has been performed successfully at five different airports. And in fact, this was the starting point to create an open version of AirCarbon. If you are interested in connecting your data to AirCarbon, please contact us.

What about Scope 1 and Scope 2 emissions and other Scope 3 emissions?

Scope 1 and Scope 2 emissions are currently not considered. These are well covered by other systems. However, it will be very important that all systems can be integrated so that airports can get a complete view of airport emissions across all scopes.

There are other Scope 3 emissions that are currently not included in the public version of AirCarbon. For example, passenger access to the airport, staff access to the airport, waste processing, electricity sold to third parties to name a few. We plan to progressively include these other sources of emissions as AirCarbon further develops.

The order in which these are included will depend on the desires of the development partners. To become a development partner, please contact us.
