The GET helps organizers in calculating the carbon footprint generated due to events. At the same time, this mandatory GET module encourages users to compensate for the nonavoidable greenhouse gas emissions. Organizers may offset using UNFCCC-recognized carbon credits, Global Carbon Council or any other program recognized under CORSIA.
GET’s carbon footprint calculator originated on UN Event GHG calculator. The calculator helps organizers estimate their GHG emissions prior to the event and later measure and compare their actual carbon footprint after the event. Offering a wide scope of GHG calculation, the tool covers carbon emissions linked with venue, international flight travel, local ground transportation, audio-visual systems, accommodation, exhibition and production, communications and catering activities.
Event Activities Recorded for GHG Calculations
Venue
The potential GHG emission sources in Venue category mainly include: stationary fuel combustion, refrigerant emissions, electricity consumption, purchased heat/cold/steam consumption, embedded carbon in building materials, water consumption, waste disposal.
Flight
Emissions from flight, in particular international flights make a significant share of the total emissions. It includes emissions from civil aviation, private aviation and freight aviation. In version 1 of this calculator, freight aviation is temporarily not considered.
Other Transportation
All the transportation except flights, including mobile fuel combustion (cars, trucks, rails, boats, other forms of transport) and upstream fuel emissions (from the production and transportation of the fuels).
Communication
Within the Communication category, for in-person events the relevant sources include material use, printing services and waste disposal. For virtual events, relevant categories include terminal devices (phone, laptop), data center and data transmission electricity consumption. For hybrid events, it is the combination of both.
Audio/Visual
Audio productions and video productions are broadly used during the events. The emissions associated with the production of such audio/video should be taken into account. In version 1 of this calculator, the user input total emission for such sources should be used.
Production/Exhibition
For events that include exhibitions or setting up temporary structures, the materials used to build the booth or other structures, and waste disposal are the relevant emission sources. The energy consumption, water consumption and other sources are usually already considered in the category "Venue".
Accommodation
For the Accommodation category, the calculation will take into account the number of rooms and nights used for the event, and the calculated emissions based on the energy index for the selected accommodation type and the grid emission factor of the country.
Catering
The catering facilities may or may not be located in the event venue. Therefore, emissions that are associated with catering services are considered separately. They include: stationary fuel combustion, electricity consumption, purchased heat/cold/steam, emission from food production (the food items themselves), and waste disposal. If the catering service is in the event venue, make sure to avoid double counting.
