How can a company turn a regulatory constraint into an efficiency driver? That is the question LogiTrans Nord (a Lille-based mid-market transport company with 380 employees) asked itself when it decided to embed fleet decarbonization into its 2026 strategy. Over eighteen months, combining smart toll transponders, on-board energy tracking, and close partnerships with mobility suppliers, the company built a sustainable and profitable fleet management model.

Fleet decarbonization: where does the pressure come from?
By 2026, European regulations require companies with more than 250 employees to publish precise indicators under the CSRD (Corporate Sustainability Reporting Directive). For transport companies, this means rigorous measurement of kilometres driven, fuel consumed, and CO₂ emitted. A conventional fleet can account for as much as 40% of a logistics company's total carbon footprint.
Finance and CSR teams are mobilizing: how do you cut the carbon bill without slowing productivity? Digital solutions (in particular next-generation toll transponders) are becoming automated reporting tools. In France, more than 80 % of companies operating ten or more commercial vehicles have already adopted a toll system, yet very few actually exploit its environmental data potential.
Watch out
Fuel-emission calculations rely on emission factors that are regularly updated (ADEME Carbon Base). Check the coefficients every year before publishing your official indicators.
The direct impact of toll transponders on emissions
At first glance, a toll transponder looks like a simple convenience gadget. Yet its contribution to fleet decarbonization is measurable. The principle is straightforward: eliminating stops and restarts at toll booths, a major source of excess fuel consumption and emissions. On a typical motorway route from Lille to Lyon, a commercial vehicle stops on average six times. Smoother traffic flow saves up to 0.5 litres of fuel per toll plaza.
Data for reporting
Modern transponders aggregate passage data (timestamp, location, average speed) that can be exported to fleet management platforms. Combined with GPS tracking and on-board telematics, this data provides a solid foundation for carbon intensity monitoring. Solutions such as Greenway, Swile Fleet, and Edenred Mobilité now offer APIs that return this information in CSRD-compatible formats.
The cumulative effect over a year
| Vehicle type | Stops avoided/year | Litres saved/year* | CO₂ avoided (kg) |
|---|---|---|---|
| Light commercial vehicle | 800 | 400 | ≈ 1,040 |
| Heavy goods vehicle | 600 | 900 | ≈ 2,340 |
| Electric vehicle (indirect gain) | - | - | Optimised charging time |

LogiTrans Nord case study: an integrated mobility strategy
Based in Lesquin, LogiTrans Nord operates 120 trucks and 90 light commercial vehicles. Facing rising non-road diesel prices and the Euro 7 standard expected in 2027, management launched a "Route 2026" plan built around three pillars: driver training, process digitisation, and targeted electrification.
Training and eco-efficient driving
Every driver completed two days of eco-driving training. Toll transponders linked to the on-board telematics system generated individual performance reports: harsh acceleration events, idling periods, high-consumption routes. Monthly feedback creates a continuous improvement loop.
Digitisation with Greenway
To centralise fuel, toll, parking, and charging-point payments, LogiTrans Nord chose Greenway, the all-in-one corporate card with impact. The platform unifies all expenses and feeds an integrated CSR dashboard: consumption, electrification rate, avoided emissions. The 1%ForAll® partnership channels a share of service fees to certified reforestation projects. The company can therefore track its decarbonization progress objectively while simplifying its accounts.
Case study
In eighteen months, LogiTrans Nord reduced overall diesel consumption by 12 %. Cumulative savings of 170,000 litres equate to 450 tonnes of CO₂ avoided, based on ADEME 2025 factors (verify). The gains came less from replacing vehicles than from the rigorous monitoring made possible by digital tools.
Avoided costs and new regulatory obligations
Setting up an environmental monitoring system is no longer optional. From 2025, any company subject to CSRD must trace Scope 1 and 2 emissions, and progressively Scope 3 (upstream and downstream chain). Carriers and their subcontractors will need to provide consolidated data.
Indicative investment schedule
| Item | Average unit cost (€) | Payback period |
|---|---|---|
| Connected toll transponder | 25–35 | 3 years |
| Integrated management platform | 300–500 /year | – |
| Eco-driving training | 250 /driver | 2 years |
| All-in-one corporate card (e.g. Greenway) | variable | – |
These costs are modest relative to total cost of ownership (TCO) and reduce administrative overhead and non-compliance risk. In addition, some regions still subsidise carbon audits and eco-driving training. Check with your regional chamber of commerce.
Upcoming obligations
Future DPEF 2027 decrees will require standardised publication of transport indicators. Start structuring your data collection now. Waiting until year-end consolidation significantly increases compliance costs.
How to structure your decarbonization roadmap
Experience shows that successful projects are planned over three years with joint steering by the CFO, CSR lead, and operations. Here is a framework adopted by many mid-market companies.
1. Diagnose
Audit your flows: fuel, kilometres, tolls, maintenance. Cross-reference them with journey times (transponder data). This diagnosis establishes your baseline in tCO₂.
2. Prioritise
Rank actions by their real carbon return. Partial electrification or the switch to biodiesel can come after organisational measures: refined scheduling, eliminating empty runs, transponders, and digital tools.
3. Equip and train
Roll out transponders and corporate cards progressively, and equip your drivers. Train them to read transponder data: a cold engine at departure or extended idling weighs heavily on your CO₂ assessment.
4. Measure and publish
Feed your CSR report with consolidated system data. Solutions like Greenway export XBRL-compatible files, simplifying handover to your statutory auditor.
Good to know
Combining a toll transponder and a corporate card on a single platform reduces finance-team administrative time by 20 %. Receipts sync automatically with management accounting.
Mini FAQ
How do I choose a toll transponder suited to a mixed fleet?
Look for an interoperable device (motorways, car parks, charging points) that can export data in real time. Check compatibility with your fleet management software.
Do electric vehicles really benefit from toll transponders?
Yes: smooth passage improves charging-stop planning. Some stations even offer dedicated lanes, cutting overall wait times.
How can I make use of the carbon savings achieved?
Include them in your CSRD report or communicate them in your CSR disclosure, but document your calculation method (ADEME Carbon Base or GHG Protocol).
Do multi-service cards like Greenway replace toll transponders?
Not entirely: they aggregate payment and reporting. The transponder remains the flow tool. The card consolidates data for a 360° view of your mobility footprint.
Can toll data be combined with internal carbon pricing?
Yes. Some companies set an internal price per tonne of CO₂ and charge an analytics cost centre based on transponder data. This incentive-based approach steers decisions towards lower-emission routes.
