METHODOLOGY
The different datasets were assessed using conversion factors and standard Emission Factors (EFs) per category.
For the fuels, we used the IMO EFs (3.114 gCO2e/gFuel for HFO and 3.206 gCO2e/gGasoil for MGO). For the electric
grid carbon intensity, we used the European Energy Agency (EEA) for Europe and published national grid intensity
outside Europe. For the business flights, we based ourselves on the Verband Deutsches Reisemanagement e.V.
(VDR) standard for business travels. For the hotel stays, we used an online calculator (hotelfootprints.org). For
the other offices and business-related metrics, we used typical emission factors, aiming at covering a Lifecycle
(LCA) approach. Finally, for the transport segment, we used the tCO2e/tkm EFs from the GHG protocol for barges,
trains and trucks, we used scientific literature for the pipelines, and reported or estimated fuel consumption for the
vessels. The estimation was done using IMOS generic vessel bunker types and various metrics from our tool Kpler.
Concerning the classification in Scope 1, 2 and 3, the following table summarizes our approach:
CATEGORY

Offices and business travels emissions
Scope 3
Commodity transports via chartered vessel,
pipeline, train or truck
