ISO 14083
CO₂ your customer asks about
A certificate for every load, using the ISO 14083 / GLEC method with default emission factors — so the report isn't your problem.
How it works
Every booking carries a figure calculated the ISO 14083 / GLEC way, well-to-wheel, from the distance and the weight actually carried.
It also shows what sharing the truck saved against sending a dedicated one — the number your customer's own report asks for.
It uses default emission factors, not metered fuel, and the certificate says so. A figure you can hand over is one nobody has to defend.
Want this on your own routes?
An account is free. You only pay when a load is actually booked.
