Are fleet emissions Scope 1 or Scope 3?

Vehicles owned or leased by the company and under its operational control are Scope 1. Grey fleet (employees’ own cars used for business) is Scope 3 Category 6. Vehicles operated by third-party logistics providers are also Scope 3 (Category 4 or 9 depending on direction).

How do I track emissions from an electrifying fleet?

Track fuel consumption for remaining ICE vehicles (Scope 1) and electricity consumption for EV charging (Scope 2). Climatise handles both, showing the net carbon reduction as EVs replace combustion vehicles. Include well-to-tank factors for complete upstream coverage.

Fleet Emissions

Fleet emissions are the greenhouse gases produced by an organisation’s owned or controlled vehicles, typically reported as Scope 1 for directly operated vehicles and Scope 3 for grey fleet.

What is Fleet Emissions?

Fleet emissions encompass all greenhouse gases from company vehicles, including cars, vans, trucks, and specialist vehicles. For organisations that own or lease vehicles under operational control, these are Scope 1 emissions calculated using fuel consumption data and DEFRA emission factors.

Fleet emissions are particularly significant for logistics, distribution, construction, utilities, and any business with a large vehicle fleet. The UK’s ban on new petrol and diesel car and van sales from 2035 is accelerating fleet electrification. Many organisations are setting interim targets to transition percentages of their fleet to electric or hybrid vehicles.

Grey fleet (employees’ personal vehicles used for business purposes) is typically reported under Scope 3 Category 6 (Business Travel). Grey fleet can be significant for organisations with mobile workforces, such as social care, sales, and field service operations.

Practical Examples

A utility company with 2,000 vans calculates its fleet Scope 1 emissions at 12,000 tCO₂e per year using fuel card data and DEFRA diesel factors.

A delivery company tracks its fleet emissions intensity (gCO₂e per parcel delivered) to measure efficiency improvements alongside the absolute emission reduction from EV adoption.

A facilities management firm discovers that grey fleet (employee car mileage claims) contributes 30% of its total travel emissions, prompting a salary sacrifice EV scheme.

How Climatise Helps

Climatise tracks fleet emissions from fuel cards, telematics, and mileage logs, calculating Scope 1 for owned/leased vehicles and Scope 3 for grey fleet. The platform monitors the transition to electric vehicles and quantifies the resulting emission reductions.
