And in carbon terms? The order of magnitude

Each tool on this site answers a question of euros. This one answers the following question, that of a CSR report: how much CO2 equivalent a bike fleet avoids when it replaces car journeys. It depends on no lease payment and no price: only on volumes, which you enter. The emission factors are the public ones from ADEME, on a life-cycle assessment basis, recorded on 29 July 2026 and displayed below the result. The kilometres are never pre-filled: it is the data that makes the result; it must come from you.

The calculation

Your volumes, never your euros

Your journeys
Pre-filled if you come from another tool on the site; always editable.
Count only the kilometres that would have been driven by car. A new journey, or one shifted from the metro, avoids nothing.
The light commercial vehicle factor is not offered: we have not yet verified it at source, and we display nothing unverified.
The scope applies to both terms of the comparison, never to one alone.
The result, from what you entered

This result is a comparative order of magnitude, rounded, based on conventional average factors: it depends on your actual modal shift, which this site does not know. It does not turn your fleet into a “carbon neutral” activity, a claim regulated by article L. 229-68 du code de l'environnement (French environmental code) that this site never makes. The electrically assisted bike factor is applied to cargo bikes, since ADEME publishes no separate cargo-bike factor: the caveat is accepted and displayed.

To gauge what is at stake: the greenhouse gas emissions report is mandatory for companies with more than 500 employees in metropolitan France, updated every four years with a published transition plan (article L. 229-25 du code de l'environnement, French environmental code). Travel emissions are part of it; a fleet of bikes is a documented lever, not an offset.

Where these factors come from

Every factor is tied to its public source and to the date on which we recorded it. Next review: 29 October 2026.

  1. ADEME, Impact CO2 / Base Empreinte, electrically assisted bike 10.95 g CO2e per kilometre in life-cycle assessment (manufacturing included); 2.23 g per kilometre in use only (charging, French electricity mix). impactco2.fr/outils/transport recorded on 29 July 2026
  2. ADEME, Impact CO2 / Base Empreinte, combustion car around 218 g CO2e per kilometre in life-cycle assessment for a driver alone; 142.25 g per passenger-kilometre at average occupancy; around 110 g per passenger-kilometre in use only. impactco2.fr/outils/transport recorded on 29 July 2026

Is the previous question a financial one?

Every tool on the site answers a question: how many bikes, what rent, company bike or pay rise, buying it yourself. The Tools menu holds them all.

Comparative order of magnitude based on public ADEME factors. Neither a regulatory report, nor an offset, nor a neutrality claim. Wander SAS addresses no costing to any given client.
