The Airport Carbon Emissions Reporting Tool
ACI’s Airport Carbon and Emissions Reporting Tool (ACERT) is a self-contained Excel spreadsheet that enables an airport operator to calculate its own greenhouse gas (GHG) emissions inventory.

|What is it?|
|ACI’s Airport Carbon and Emissions Reporting Tool (ACERT) is a self-contained Excel spreadsheet that enables an airport operator to calculate its own greenhouse gas (GHG) emissions inventory. The tool is available at no cost to airports and can be used without emissions or environmental expertise by inputting readily available operational data. |
Methodologies are consistent with the ACI Guidance Manual on Airport Greenhouse Gas Emissions Management and the GHG Protocol. Emissions are divided according to ownership and control of the source:
|Scope 1 - emissions owned and controlled by the airport operator, such as electricity generation and airport vehicles.|
|Scope 2 - emissions from the off-site generation of electricity or heating/cooling purchased by the airport operator.|
|Scope 3 - emissions owned and controlled by airport tenants and other stakeholders including:|
|Why use it?|
|In order to manage GHG emissions, an operator needs to understand the sources, quantities and ownership of emissions at the airport. An inventory can help the airport operator to set goals and target mitigation efforts. |
In addition ACI would like to use ACERT data to compile regional and global aggregate emissions, enhancing understanding of airports’ contribution to total aviation industry emissions.
|Who can use it?|
|ACERT can be useful for:|
|Input for ACERT can be completed by operations, planning or maintenance staff with no emissions training or expertise.|
|How does it work?|
|Data are entered into a self-explanatory Excel spreadsheet. For the calendar year of the inventory, the following information is needed:|
|What are the outputs?|
|ACERT automatically generates an inventory report (see sample extract on following page) that includes a summary table of GHG emissions, and pie charts. This stand-alone report also contains detailed notes on the assumptions and caveats and a check-list to aid review (not illustrated here). In addition, version 5.0 will start providing you with the necessary information needed to transfer from ACERT to the Airport Carbon Accreditation Online Application Portal. In addition to providing the necessary information needed to transfer from ACERT to the Airport Carbon Accreditation Online Application Portal, version 5.0 also brings a new structured presentation of results that includes Key Performance Indicators (KPIs).|
|How good is it?|
|An ACERT inventory is of sufficient quality to help set up an airport GHG reduction programme. The tool has been tested at several major airports including Zurich, Toronto and SeaTac. Results indicate that ACERT Scope 1 and 2 emissions were within 5-10% of those from a more detailed inventory calculation. |
Jaime Pérez Basantes, Environment Manager at Corporacion Quiport and Chair of the ACI LAC Environment Committee, has used ACERT himself at Quito Airport and found the ACERT tool very simple and helpful: “ACERT is a wonderful solution to calculate the airport’s carbon footprint and it is very easy to use. Once the airport has the necessary information, ACERT will do everything for you and appropriate results will be shown at the output report.”
ACERT v5.0 is especially designed to calculate emissions for all Levels of Airport Carbon Accreditation: 1 Mapping, 2 Reduction, 3 Optimization and 3+ Neutrality.
Airport Carbon Accreditation is the only airport-specific carbon management standard and is now available globally in all five ACI regions (www.airportcarbonaccreditation.org).
Version 5.0 features construction activities and refrigerants as a new emission sources; updated emission factors for most modelled emissions; enhanced and modified emissions report with results, KPIs and graphical charts.
ACERT should not be used in place of any model required by local regulation.
