Fuel you burn in vehicles and equipment you control is Scope 1. Fuel burned on your behalf by someone else is usually Scope 3.
What you need
Litres, by fuel type, for the period.
Fuel card exports are the best source. They give you volume, date, site and fuel type in one file.
If you only have spend, you can calculate from that, but the result is weaker. Move to volume when you can.
Which fuel is yours
Situation | Scope |
Vehicles you own or lease and operate | Scope 1 |
Equipment on your sites, such as forklifts and generators | Scope 1 |
Employee's own car, reimbursed per kilometre | Scope 3, business travel |
A contractor's vehicle doing your work | Scope 3 |
A company car charged at an employee's home | Scope 1 if you control the vehicle |
The test is control of the asset, not who paid for the fuel.
Blended fuels
E10 is ethanol blended into petrol. B20 is biodiesel blended into diesel.
Check whether a factor exists for the blend before you split it. If it does not, either apply the blend ratio across two factors, or use the base fuel factor and note the assumption.
Record the approach.
Contractor fuel
Fuel burned by a contractor working on your site is theirs to report as Scope 1, and yours as Scope 3.
Electric vehicles
Electricity for a vehicle you control is Scope 2, not Scope 1.
Charged at your site, it is already in your site electricity. Do not count it twice.
Charged at an employee's home, it is either out of scope or a small Scope 3 item depending on your boundary. Decide and record it.
Charged at a public charger, treat it as purchased electricity.
Getting it into Avarni
Upload litres by fuel type against a Method configured for mobile or stationary combustion. Map the site using a vehicle registration or a cost centre so the fuel lands at the right facility. See Set up your entities and facilities.
If your fuel card export names the site, map that instead.
