This data point captures greenhouse gas (GHG) emissions from mobile sources that are part of your organization’s operations, as calculated by an external provider such as a fuel supplier, telematics service, or fleet management company.
It applies to all company-owned or controlled vehicles, both light-duty (under 3.5 tonnes) and heavy-duty (over 3.5 tonnes). The emissions are expressed in metric tonnes of CO₂ equivalent (tCO₂e) and should be based on externally verified calculations, not internal estimates.
What to include:
Include all GHG emissions from mobile sources that meet the following conditions:
Vehicles are owned or directly controlled by your company
Emissions data comes from an external provider using verified calculation methodologies
Covers both under and over 3.5-tonne vehicles (combined total)
Includes all fuel types (diesel, petrol, CNG, LNG, biofuels, etc.)
Reported in tCO₂e
What not to include:
Emissions from leased vehicles where the lessor is responsible for reporting
Privately owned vehicles used for business travel (covered under business travel in Scope 3)
Internal estimates calculated without external verification
Non-road mobile machinery emissions (unless explicitly included in the external provider’s scope)
Estimation Methodology:
Since this data point is based on external calculations, no internal estimation should be performed for missing months.
If the external provider’s data does not cover the full year, request them to provide a pro-rated or annualized figure using their methodology.
In cases where an annual figure is unavailable:
Gather partial-year emissions data from the provider
Calculate monthly average emissions from available data
Multiply by total months in the reporting year
Clearly document that the figure is provider-adjusted
