Airport Carbon and Emissions Reporting Tool (ACERT) v.5.1

ACERT offers:

  • A method to measure an airport’s greenhouse gas emissions (GHG) by source
  • The opportunity to evaluate the airport’s environmental footprint and emission performance without technical expertise
  • The ability to track and improve environmental performance

What is ACERT?

The Airport Carbon and Emissions Reporting Tool (ACERT) is a simple IT solution that calculates GHG emissions at and around the airport.

What information does it provide?

ACERT generates a comprehensive airport GHG emissions inventory report, highlighting its performance based on emission intensity. Summary tables, charts, graphs and a carbon neutrality path are also produced based on input values.

Who can use it?

Any airport, regardless of size or in-house expertise. Designed by airports for airports, this tool is available at no cost to airports. It does not require emissions or environmental expertise as only readily available operational data is needed.

Can it be used for Airport Carbon Accreditation (ACA)?

Yes! ACERT is designed to calculate emissions for all four levels of Airport Carbon Accreditation, and provides necessary information for the Airport Carbon Accreditation Online Application.

Airport Carbon Accreditation is the only airport-specific carbon management standard and is now available in all five ACI regions. (www.airportcarbonaccreditation.org).

What is the methodology used?

ACERT emissions calculation methodologies are consistent with the:

  • ACI Airport Greenhouse Gas Emissions Management Guidance Manual
  • GHG Protocol - Corporate Accounting and Reporting Standard by World Business Council for Sustainable Development (WBCSD) and World Resources Institute (WRI)

Airport Emissions are divided according to ownership and control of the source:

  • Scope 1- emissions owned or controlled by the airport operator
  • Scope 2- emissions from the off-site generation of electricity and/or heating/cooling purchased by the airport operator
  • Scope 3 - emissions owned or controlled by airport tenants and other stakeholders working at or around the airport

ACERT additional information

  • By using ACERT, users agree to the ACERT software licensing agreement. ACERT should not be used in place of any model required by local regulation.
  • ACI encourages all airports using the ACERT tool to participate in our data collection initiative. Enhancing the understanding of airports’ contribution to total aviation industry emissions is extremely important for better representation of airports’ interests. For those who wish to participate, please send your ACERT output report to us at ACERT@aci.aero. This information will be kept confidential and only be shared in an aggregated format. Please do not hesitate to contact us at ACERT@aci.aero should you need any further clarification.
