Summary
This section provides an overview of the methodology that will be applied to the GHG assessment. It defines why the specific data is relevant, how it will be measured, and what categories or frameworks are used.
Why consider emissions from Business travel and vehicle fuel consumption?
Purpose: This module can represent one of the major field of emissions, and is also used to account for emissions in scope 1& 2
*This module doesn’t take into account the amortization of the company’s vehicle fleet. If applicable, use the vehicle fleet module *
Type of raw data
Granularity: For each type of travel, the details on the distance, fuel, travel class Example Data Format:-Granularity: Usually one line per travel
Measured Values: Indicate the total purchased volumes (e.g., in KG) for each product.Important Note: Refer to the Data Collection Guide for more details.

Emissions should include
Combustion, Upstream energy and Manufacturing infrastructure + vehicles (when not taken into account elsewhere, e.g. vehicle fleet module)

Contrails
Certaines activités ont un impact sur le changement climatique qui n’est pas uniquement lié aux émissions de GES. Cet impact est associé à d’autres phénomènes physico-chimiques qui n’impliquent pas le forçage radiatif d’un GES. Il peut s’agir par exemple des traînées de condensation de la vapeur d’eau en sortie des réacteurs d’avions. Ces phénomènes peuvent être complexes, difficiles à appréhender et dépendent des conditions climatiques extérieures. Le choix a été fait de prendre en compte le pouvoir de réchauffement global lié aux trainées de condensation.
Note: For air travel emission factors, multipliers or other corrections to account for radiative forcing are applied to the GWP of emissions arising from aircraft transport.

Methodology & EF Classification
Train
This category uses different EFs depending on the trainType and the country:
For European countries, if the country is in our database, we will use the ADEME EF - not specific to a train type unless it is France.
The French EFs will be used as fallback for the BEGES methodologies, with 2 EFs depending on the trainType (Regional / High-speed)
The UK database will be used as fallback for the GHG P methodology, with 2 EFs depending on the trainType (Regional / High-speed)
The monetary approach is available, using country specific MEFs, and French one as fallback.
Flight
All the EFs used are counting the Greenhouse effect of contrails in addition to the fuel upstream+consumption, and manufacturing for BEGES.
Effective impact of contrails is still uncertain, but it is assumed to be responsible of about half of the warming potential of a flying plane, by increasing radiative forcing.
This category uses different EFs depending on the distance travelled and travel class:
Short-haul EFs will be used for distances < 3500 km (tag Distance “BETWEEN_1000_AND_3500”), and Long-haul EFs for higher distances (tag Distance “GT_3500”)
Different EFs will be used depending on the methodology: BEGES will account for the manufacturing of planes, while GHG P will only account for upstream fuel and combustion.
For short-hauls, we differentiate “ECONOMY” (also used as fallback) and “BUSINESS or FIRST” classes.
For long-hauls, we differentiate “ECONOMY”, “BUSINESS” and “FIRST”
GHG P Emissions Factors come from the UK GHG Database, while BEGES ones are calculated using ADEME as base value, and extrapolated using UK Database, to match the different travel classes. (details here, “Flights - EF ADEME vs UK” tab)
The monetary approach is available, using country specific MEFs, and French one as fallback.
Car
Short lease vs Owned or Long-term lease
Short lease emissions will be reported under scope 3, while Owner/long-term ones will be reported under scope 1& 2 (with upstream still going under scope 3)
Emissions factors for distances
Are specific to each vehicle type: gas, diesel, electric or hybrid
Thermal vehicle: EFs are based on ADEME Base Empreinte database for all countries, except UK and US which are respectively using UK GHG Database and EPA
Electric or Hybrid: EFs are based on specific Greenly studies and research papers, except UK and US which are respectively using UK GHG Database and EPA
Taxi: Two EFs coming from ADEME Base Empreinte are used depending on the fuel type: Green taxi when the fuel type is electric, Taxi otherwise.
Emission factors for fuel consumption
Are specific to each vehicle type: gas, diesel, electric/hybrid
Thermal vehicle: EFs are based on ADEME Base Empreinte, for gas and diesel
Electric or Hybrid: Are using IEA 2023 EFs for electricity consumption (except for France which uses ADEME) - Hybrid vehicles here are considered plug-in hybrid.
Monetary emissions factors
The monetary approach is available, using country specific MEFs, and French one as fallback. MEFs are specific to each fuel type.
Hotel
Impact per night: EFs are coming from the CORNELL HOTEL SUSTAINABILITY BENCHMARKING INDEX 2024 and are country specific, using regional EFs as fallback
The monetary approach is available, using country specific MEFs, and French one as fallback.
