Shippers now ask for carbon per shipment, not an annual total. An answer filled with average factors collapses under the follow-up question: “is this measured?” The demand has already started, and it is becoming a condition of the next contract.
The problem is that the data is scattered across the field. Fuel use per vehicle, cargo weight, empty and return-leg distance, actual distance driven — the moment a shipper asks, none of it is organized anywhere. Average factors inflate precisely because they fill that gap “as if” the load were there.
The DTG measures each trip at 1-second resolution. It identifies and removes empty return legs as they are, and feeds only the activity you actually carried into the ISO 14083 methodology. Numbers that begin with measurement, not estimation.
The result is per-shipment emissions you can hand your shippers as-is. The basis is sealed to measured activity data, so when a shipper asks you to verify, you return the same number.
Frequently asked
Not necessarily. Trips with many empty legs come out higher than average factors; full loads come out lower. The point is not direction — it is a defensible number that passes shipper verification.
The DTG collects trip data over OBD-II. Specific fit conditions can be confirmed via the product detail and an inquiry.
