Introduction about the studied activity
The aim of the vehicle fleet study is to analyze the carbon impact of your companyâs vehicles according to two elements: the carbon impact of their construction and the carbon impact of their usage (I.e.: fuel or electricity consumption).

Greenlyâs methodology for delivering the analysis
Construction carbon impact:
For each vehicle type and each motorization, an emission factor in kgCO2e/vehicle has been associated, along with a by default lifetime (5 years for motorcycles and scooters, 10 years for all other vehicles) and a reference weight in kg.
This database has different sources: ADEME, Ecoinvent, manufacturers data files and Greenlyâs expertise. Depending on the methodology used, calculations are processed as followed:
BEGESÂ (for French companies) for owned or leased vehicles: the construction impact of a vehicle is taken into account, divided by the expected amortization period of the vehicle. For example, emissions related to a city car emitting 6700 kgCO2e at its construction and amortized for 10 years will register a 670 kgCO2e impact in the GHG assessment.
GHG Protocol for owned vehicles: the whole construction impact of a vehicle is taken into account only if it has been bought in the course of the studied year. For a 2022 GHG assessment, a car bought in 2021 will then have no construction impact registered.
GHG Protocol for leased vehicles: the methodology assesses that there is no construction impact to be registered for leased vehicles, usage impacts are taken into account.
In the data collection file, you have the possibility to indicate the weight and amortization period of each of your vehicles. This way, calculations will use these values instead of the by default ones and deliver results closer to the reality of your vehicles. If you donât have access to this type of data, the by default values allow getting universal results.
Usage carbon impact:
In the data collection file, you have two possibilities to study the impact of your vehicle fleet usage:
Vehicle per vehicle: you have access to a list of several types of consumption data (kilometers, miles, kWh of electricity, liters of fuel, gallons) so you can enter the consumption value per vehicle according to the selected unit
Global consumption: if you donât have available data per vehicle, you still have the possibility to provide general figures by type of motorization according to a selected unit (kilometers, miles, kWh of electricity, liters of fuel, gallons).
For both scenarios, a database of emission factors in kgCO2e/L or kgCO2e/kWh allows assessing the usage carbon impact, and a second database provides conversion ratios per vehicle type, from the initial unit chosen (kilometers, miles, kWh of electricity, liters of fuel, gallons) to L or kWh in order to get a final emission factor in kgCO2e/unit chosen.
General results
The goal of this study is to provide you insights of various analysis:
Total emissions (construction and usage) per vehicle
Global emissions by motorization type
Global emissions by life cycle stage (amortization, usage)
Global emissions by type of fuel used
