Even estimates
have rules.
Carbon accounting isn’t a hunch — it’s a method. ISO 14083 defines the boundary transport emissions are counted in, how they’re split, and how they reproduce. We show that method here — and why it has to be measured, not estimated.
Same input, same result.
Well-to-Wheel boundary
Not just burning the fuel (TTW) but producing and delivering it (WTT) — the whole Well-to-Wheel path is inside the boundary.
ton-km allocation
When one vehicle carries several shippers’ cargo, emissions are split precisely by measured distance and weight (ton-km).
Five transport modes
Road, rail, air, sea, and hub under one method — mixed modes don’t become inconsistent calculations.
Deterministic
The same trip data yields the same emissions whenever you compute it — it reproduces under audit years later.
An estimate is only the start.
An estimate from published factors points the way but can’t go into a report as-is. What shippers require is measurement — actual data read at the vehicle every second. LCS produces that measurement.
