CO₂e calculator for transports
Free CO₂e calculator for transports with map, distance estimation, HVO100 option and comparison of different transport modes.
Every trip leaves CO₂ behind. The only question is whether you can quantify it — or merely estimate.
Start calculation
Enter origin, destination and shipment data. You can determine the distance automatically via the map or override it manually.
Result by Well-to-Wheel
Calculating …
The best option is derived automatically from all selected transport modes after the distance calculation.
Breakdown of CO₂e into upstream chain (Well-to-Tank) – extraction and provision of the energy carrier – and operation (Tank-to-Wheel).
EN 16258, GLEC and ISO 14083 require both shares to be reported separately. To the methodology – read on →
Estimated air pollutants for the selected scenario – guide values, not audited values.

Auditable pollutant and particulate balances per HBEFA/ISO 14083 are available in the .
Same route, just a different mode: the distance stays identical, the emission factor and modal logic change – so you immediately see the cheapest alternative.
Emissions per leg of the route – when Multimodal is active, with its own mode per leg (e.g. truck · ferry · truck).

The page focuses on three things: fast data entry, clear results and transparent comparison of different scenarios.
Present the lane cleanly, both visually and numerically.
Diesel, HVO100 and alternative transport modes side by side.
Less text up top, more focus on the tool and the result.
Notes on the logic
- The calculation is a practical preliminary estimate, not a certified ESG report.
- Pallets are converted at a default of 0.50 t per pallet. This value can be adjusted.
- Utilization acts as an efficiency lever: lower utilization increases emissions per transported tonne.
- HVO100 is modeled as a significantly lower-emission scenario, but works best as a comparison and sales argument.
Auditable CO₂e report & more
The free calculator delivers reliable guide values. For tenders, ESG reporting and customer evidence there is the audited version – on request, without automatic activation.
- Report per ISO 14083, EN 16258 & GLEC (PDF & Excel)
- External costs (climate, air pollutants, noise) in euros
- Auditable pollutant & particulate balance (HBEFA)
- Fleet upload (Excel/CSV) & empty-run analysis
- API integration for entire transport chains
Open-source project. The free calculator stays free; the additional functions are provided exclusively on request and after approval – no automatic access.
Fewer kilometres before CO₂ even arises
The CO₂e calculator quantifies the emission per lane. Route and tour optimisation starts one step earlier and cuts the kilometres from which the emission arises in the first place — a short sequence, fewer empty runs. Together that gives both: drive less and evidence what remains. The video explains it in 30 seconds.
Every tour starts with many stops – loading, unloading, return trip.
