Truck CO₂ emissions calculator, per km and per route
Well-to-Tank, Tank-to-Wheel and total Well-to-Wheel CO₂e for any road freight route in Europe, with the GLEC v3.0 / ISO 14083 method. Free, no signup.
CO₂ emissions per km by truck type
Reference figures from the calculator's own method: average consumption per vehicle class and GLEC v3.0 / ISO 14083 emission factors (DEFRA 2024). Real figures depend on load, route and driving.
| Truck type | Consumption | kg CO₂e per km | kg CO₂e per 100 km |
|---|---|---|---|
| Diesel Tractor-Trailer (40t) | 32 L/100 km | 1.07 | 107 |
| Diesel Rigid Truck (7–18t) | 22 L/100 km | 0.73 | 73 |
| Electric Tractor-Trailer (40t) | 120 kWh/100 km | 0.36 | 36 |
| HVO Tractor-Trailer (40t) | 32 L/100 km | 0.13 | 13 |
| LNG Tractor-Trailer (40t) | 25 kg/100 km | 0.85 | 85 |
Well-to-Wheel: fuel production and transport (WTT) plus exhaust (TTW). HVO shows a lower figure because the biogenic credit is applied at production, per GLEC.

Assumptions: city-level distance estimate, average consumption per vehicle class, GLEC v3.0 / ISO 14083 — DEFRA 2024 factors.
When do you need a CO₂ certificate for a transport?
ISO 14083:2023 is the standard for quantifying and reporting greenhouse gas emissions from transport chains, and the EU's CountEmissionsEU regulation makes it the mandatory method for any transport emissions figure that is published. Large shippers already ask carriers and forwarders for emissions per shipment in tenders; smaller operators are asked next.
EleFleet issues a CO₂ certificate per shipment, computed with the ISO 14083 / GLEC method from the distance and vehicle on the CMR, with the method stated on the document. It comes with every account, including the free one.
Frequently asked questions
How is truck CO₂ calculated?
Distance times the average consumption of the vehicle class gives the fuel used; fuel times an emission factor gives CO₂e. Each fuel has two factors: Tank-to-Wheel for the exhaust and Well-to-Tank for producing and transporting the fuel. Their sum is Well-to-Wheel. This is the GLEC v3.0 / ISO 14083 method.
What is the difference between WTW, TTW and WTT?
TTW (Tank-to-Wheel) is what comes out of the exhaust. WTT (Well-to-Tank) is what it took to produce and deliver the fuel or electricity. WTW (Well-to-Wheel) is the sum, and the figure reports and tenders ask for.
How much CO₂ does a truck emit per km?
About 1.07 kg CO₂e per km well-to-wheel for a 40 t diesel tractor-trailer at 32 L/100 km, 0.73 kg for a 7 to 18 t rigid truck at 22 L/100 km, and 0.36 kg for an electric 40 t tractor at 120 kWh/100 km on the EU average grid. The table above lists each type.
Is a CO₂ certificate mandatory?
Not yet for every shipment. CountEmissionsEU makes ISO 14083 the mandatory method whenever transport emissions are reported, and tender requirements are spreading from large shippers down the chain. Having a certificate per shipment ready costs nothing with EleFleet and answers the request the day it arrives.
Is the calculator free? Do I need an account?
The calculator is free and needs no account. Per-shipment certificates, with the vehicle and distance of the actual CMR, come with a free EleFleet account.
