How to measure emissions from Employee car liquid fuels
Employee car liquid fuels covers petrol and diesel bought directly by an employee for a business trip in their own car - typically reimbursed via fuel receipts or a fuel card - and sits under Scope 3 Category 6. Record litres or spend from fuel receipts and fuel-card statements. Use this instead of a mileage-based business-travel entry whenever you hold fuel data rather than a distance claim.

What counts as Employee car liquid fuels
Liquid fuel purchased directly by employees for their own vehicles used on business trips, then reimbursed by the organisation through a fuel-card or fuel-receipt arrangement, distinct from a straightforward mileage claim. Covers petrol and diesel purchases tied to business use of a privately owned car.
This sits in Category 6 (business travel) alongside the road, rail, air and sea business-travel pages, but it is fuel-specific rather than distance-specific: use it when you hold fuel receipts or fuel-card data rather than a passenger.km mileage claim for the same trip. It is separate from the 'Employee commuting' pages, which cover home-to-work journeys (Category 7) rather than business travel. Enter each trip's fuel under one method only - fuel data or mileage claim, not both - to avoid counting the same journey twice.
How to collect the data
Fuel card statements and expense claims with fuel receipts are the main sources, giving litres and spend per employee or per fleet. Where only total litres are available (for example, from a fleet fuel-card provider's summary report), that is the physical unit to use; fall back to £ spend only when receipts show cost but not volume.
What activity data you need
Collect the most specific physical unit available. Unit definitions are in Appendix I — Description of Units.

Which emission scope it falls under
Employee car liquid fuels activity data typically maps to Scope 3 Category 6 under the GHG Protocol. Confirm organisational boundary and ownership before reporting.

Common questions
- How is this different from claiming mileage for a business trip?
- A mileage claim uses distance (passenger.km or km) on the 'Business travel: Road' page. This page uses actual fuel receipts or fuel-card data - use whichever record you actually hold, not both, for the same trip.
- Which fuel purchases count as business use versus personal?
- Only fuel tied to a claimed business trip counts here. Personal fuel purchases, even on a company fuel card, fall outside the organisation's business-travel boundary.
- What if an employee's fuel receipt covers a mixed personal/business tank fill?
- Apportion the receipt using the business mileage share of that tank of fuel, based on the employee's expense claim, rather than counting the full receipt as business use.
- Do company car fuel purchases belong here or in Scope 1?
- If the vehicle is owned or leased by the organisation, fuel use is typically Scope 1. This page is for fuel bought for an employee's own privately owned vehicle used on a business trip.
- Should I convert litres to kWh myself?
- No - enter the litre figure as recorded on the receipt or fuel-card statement and let the platform apply the correct factor for the fuel and subtype selected.
