The ICAO Green Meetings Calculator (IGMC) provides an easy-to-use interface consistent with the ICAO Carbon Calculator methodology that can support decision-making to select venues for meetings with the minimal carbon footprint from air travel. This calculator 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 facilitates the planning process.
