Your emissions are in the fuel, and the trucks you hire in
A freight footprint lives in fuel, and in the carriers you subcontract, and the evidence is scattered across depots and formats. Turning it into a per-route number you can defend is a data problem first. The analyst does that work from your fuel-card and telematics data, and shows the factor behind every line.

Fuel-card data in, a defensible per-route number out
The evidence is scattered: fuel-card exports, telematics feeds and consignment records, in different formats across every depot. The analyst reconciles litres to each vehicle, matches the right factor, and produces a per-route footprint with the source, factor and reasoning shown, so it holds up when an assurer asks.

How it works
Drop in fuel-card exports, telematics and consignment data, the analyst calculates each scope with matched factors, and you report per route, per depot or consolidated across the network.

Fleet fuel
For a carrier that runs its own trucks, fuel is the footprint. CO2 Lab reads fuel-card and telematics data per vehicle, applies the current NGA factor for each fuel and blend, and reports emissions on a well-to-wheel basis rather than tailpipe only.

Scope 3 · Category 4
Subcontracted freight
Most operators move a lot of freight on other people's trucks, and rarely get fuel data back. When the carrier stays silent, CO2 Lab takes the consignment data you do have (weight, distance, mode) and applies GLEC and ISO 14083 intensities, flagging exactly where the number is a default rather than measured.
Intensity
Load and empty running
Two trucks burning the same diesel can carry very different footprints per tonne moved. CO2 Lab reports emissions per tonne-kilometre, so a better load factor or a backhaul that cuts empty running shows up as a real reduction, not a rounding difference.
