The team will answer you within the hour!
You are a CFO or finance director
Your fleet TCO is an average. Your auditors want a measurement.
10 to 15% less fuel, observed at our clients when the programme is driven by management, including −12% at Eiffage Rail (2022-2025), and emissions data that stands in a CSRD file: the same per-vehicle measurement serves your cost line and your reporting line. Measured, vehicle by vehicle.
Your reality
Your TCO is an average, not a measurement.
Manufacturer consumption figures, flat insurance fees, claims provisions: you are steering estimates. The real gaps show up at year end, when it is too late to act.
Your emissions reporting inherits the same weakness.
CSRD and ESG reporting expect reliable, traceable data. Most fleet figures are built on average emission factors and theoretical mileage: a number that describes an average vehicle, not yours, and that struggles in front of an auditor.
For your French operations: the tax stakes have changed scale.
In France, the flat-rate valuation of the company-car benefit-in-kind (avantage en nature) rose sharply in 2025, and France’s annual incentive tax (taxe annuelle incitative, TAI) tightens year after year. With proof of actual use, the gain can be in the order of €2,000 per vehicle per year, employer and employee gains combined. A French-market lever worth checking if you run vehicles there.
Results

Put a figure on it
Three minutes to put a figure on what is at stake.
Your number of vehicles and your annual fuel budget are enough for the cost side. For your French operations, add your purchase/lease mix: the simulator also returns the gap between flat-rate and actual-use benefit-in-kind, and your TAI trajectory. Your data, not a market average. Simulators in French.
Actual-use benefit-in-kind simulator
For your French operations. Flat rate or actual use: how wide is the gap on your payroll? Both sides of the gain, company and driver. Two minutes.
TAI 2026 simulator
Does the TAI apply to your French fleet? Estimate what it represents in 2026, and what greening the fleet changes on the bill.
Where to start
Carbon footprint & CSRD reporting
Emissions measured from real fuel and energy use, vehicle by vehicle, time-stamped and traceable. We provide the reliable data; the report and its audit remain with your company and its auditor. The clean boundary that gives a finance department confidence.
Connected eco-driving
10 to 15% less fuel, observed at our clients, including −12% at Eiffage Rail (2022-2025). Fuel stops being a budget fatality and becomes a figure you can manage.
Let us be frank
“We already report emissions with standard emission factors.”
An average factor describes an average vehicle in average conditions, not yours. It misses driving style, real loads, cold starts, and plug-in hybrids that never get plugged in, and it rarely survives close scrutiny. Measuring real consumption means measuring emissions instead of estimating them: per-vehicle, time-stamped data that an auditor can trace. The day you are asked to justify your figures, you show data, not a reconstruction.
30 minutes to go from estimate to action plan.
We look at your fleet, your mix, your tax calendar. You leave with a clear view of the gap, and of what it takes to close it.
