Overview
The Business Travel & Fuel Consumption module covers travel and fuel emissions across rail, air and road, including cars owned and leased by the reporting company, plus optional hotel stays.
Key use cases
Accounting for business travel from distance, fuel, duration or spend-based inputs
Correctly splitting emissions between business travel and owned or leased vehicles
Running the same process for GHG Protocol and BEGES-R
What this module covers
The module covers emissions from:
Rail travel
Air travel
Road travel, including cars owned and leased by the reporting company
Hotel stays (optional)
How the module works
For each activity, the company selects options (for example train plus high-speed) that define an identifier. That identifier is then used to select the emission factor.
How emission factors are matched
EFs are selected by filtering on:
Identifier: the option selected. For example, "train" plus "high-speed" filters all high-speed-train EFs.
Methodology: GHG Protocol or BEGES-R
Unit: the EF whose unit matches the data provided (distance in passenger.km or km, fuel in kWh or L, duration in nights, amount in currency)
Country: the EF with a matching country ID or region, with a default when there is no match (ADEME Base Empreinte for BEGES-R, UK Defra for GHG Protocol)
Year: the EF with the closest year
Scope allocation
Scope 3.6 Business travel: rail travel, air travel, road travel on short-term lease and taxi, and hotel stays (optional)
Scope 1 (mobile combustion) or Scope 2 (electricity consumption): road travel in owned vehicles and long-term leases
Emission factor sources
IEA for electricity consumption
Hotel Sustainability Benchmarking Index for hotel stays
Exiobase or Greenly monetary emission factors for the expense approach
Otherwise: Base Empreinte for French and BEGES-R options, UK Defra for the UK and GHG Protocol, US EPA for the US and GHG Protocol
FAQs
Why do some car trips fall under Scope 1 or 2 instead of business travel?
Road travel in vehicles owned by the company or on long-term lease is allocated to Scope 1 (mobile combustion) or Scope 2 (electricity), while short-term lease and taxi stay in Scope 3.6.
Can I use a spend-based input?
Yes. An expense approach is available and uses Exiobase or Greenly monetary emission factors.
Which unit should the data be in?
The module matches the EF to the data unit provided: distance (passenger.km or km), fuel quantity (kWh or L), duration (nights) or amount (currency).
