This data point measures the total volume of diesel fuel consumed by vehicles owned or directly controlled by your organization during the reporting year. The data should be reported in liters and should cover all operational vehicles, regardless of size or weight class (light-duty vans, trucks, specialized equipment on wheels).
What to include:
Diesel fuel consumed by:
Light-duty and heavy-duty vehicles
Specialized mobile equipment registered for road use
Any vehicle under your direct operational control
Fuel purchased and consumed within the reporting year
Data from all relevant sources: fuel cards, receipts, fleet management systems
What not to include:
Diesel used in stationary equipment (covered under stationary combustion data points)
Fuel purchased but not consumed in the reporting year
Privately owned vehicles used for business travel (covered under Scope 3 – Business Travel)
Leased vehicles where the lessor is responsible for fuel supply and reporting
How to Approach On-Site Fuel Stations (Subsidiaries Operating Their Own Refuelling Points)
When a subsidiary operates its own on-site fuel station, all fuel dispensed and subsequently burned in company-owned or company-controlled vehicles is reported under Scope 1.
The key rule: fuel combustion under the company’s control = Scope 1 emissions.
Total Amount of Fuel Dispensed (Litres or kg) per Fuel Type
The subsidiary should collect and report into Green0meter:
Total litres (or kg) of fuel dispensed per month or per quarter
Broken down by fuel type (e.g., diesel, petrol, biodiesel, HVO, LPG, CNG)
Suitable data sources include pump meters, tank management systems, bulk purchase invoices, or manual logs.
What Not to Do
Do not report these emissions under Scope 3.
Even though the fuel is purchased, it is burned internally → Scope 1.
Do not calculate emissions based on kilometres driven when you have actual fuel consumption data.
Litres dispensed provide a more accurate and auditable dataset.
Do not mix internal fuel use with fuel sold externally (see Case A below).
Special Cases to Be Aware Of
Case A: The Subsidiary Also Sells Fuel to External Parties
If any portion of the fuel is dispensed to external customers:
This fuel must not be included in Scope 1, because it is not burned by the company.
Green0meter will automatically calculate the corresponding Scope 3 Category 3 emissions once the user enters the volumes sold externally.
Therefore, the subsidiary must keep separate records of:
fuel consumed internally, and
fuel sold externally
Users only enter the volumes; Green0meter assigns them to Scope 1 or Scope 3 automatically.
Case B: Fuel Used for Non-Road Machinery
If the on-site station also fuels:
Construction machinery
Forklifts
Heavy equipment
Generators
→ All of this remains Scope 1, as it is still fuel combusted by company-controlled equipment.
Estimation Methodology:
If full-year diesel data is incomplete:
Compile actual consumption for all available months
Calculate the monthly average
Multiply by the number of missing months
Add the estimate to the actual total
