How do we count emissions from technicians visiting customer sites?
It follows who owns the vehicle. Company vehicles are Scope 1 from their fuel invoices. Technicians using their own vehicles and claiming mileage are Scope 3 Category 6, as are taxis, trains and hotel nights. A contracted service partner's emissions are part of what you buy, Scope 3 Category 1.
Data to keep
- Fuel invoices for company vehicles.
- Mileage claims with km per trip.
- Travel and hotel bills.
- Invoices from service partners.
Per visit figure
Divide the year's service emissions by the number of visits if a customer asks for a per-visit number, and say what is included.
What Senseible does here
Senseible reads supplier invoices into dated records with the quantity, unit and factor on each line, and marks lines without a usable quantity as needing data instead of guessing.
