ICAO Green Meetings Calculator

 The ICAO Green Meetings Calculator (IGMC) is a tool designed to support decision-making in reducing the carbon emissions from air travel to attend meetings.
The software generates an optimal location for a meeting in terms of CO2 emissions, taking into consideration the city of origin and the number of participants, as well as other parameters. While many factors may affect the decision for where a meeting should be held, the calculator helps facilitate the planning process.
Access the files here: ICAO Green Meetings Calculator (requires Microsoft Windows XP or newer) and the IGMC User Guide.

The Green Meetings Calculator is additionally available in the Apple App Store as an iPhone and iPad application.

​ICAO Fuel Savings Estimation Tool

 Operational measures are one of the instruments available to States to improve fuel efficiency and reduce CO2 emissions. The ICAO Fuel Savings Estimation Tool (IFSET) has been developed by the Secretariat with support from States and international organizations to assist the States to estimate fuel savings in a manner consistent with the models approved by CAEP and aligned with the Global Air Navigation Plan.

The ICAO Fuel Savings Estimation Tool (IFSET) is not intended to replace the use of detailed measurement or modelling of fuel savings, where those capabilities exist.  Rather, it is provided to assist those States without such facilities to estimate the benefits from operational improvements in a harmonized way.
