France is the anomaly that proves the policy rule. Third in EU electric truck registrations (1,713 in 2025), home to Renault Trucks’ electric range and to sophisticated logistics groups, it nonetheless lacks the single most powerful incentive its neighbours deploy: a CO₂-graded distance toll for trucks. The consequence shows in the data — French volumes grow, but without the step-change the Netherlands achieved once grant met toll.

What the toolbox contains. The workhorse is tax treatment rather than cheques: suramortissement — enhanced depreciation for clean commercial vehicles — improves the corporate-tax position of an electric truck purchase, and ADEME-administered calls periodically support fleet decarbonisation and charging projects, particularly for SMEs and specific programmes (grants, studies, demonstrators). Regional and city regimes add operational privileges: low-emission zones (ZFE) in Paris, Lyon and other metros progressively restrict diesel access, which converts urban and regional distribution contracts into de-facto electrification mandates. Ecological bonus structures exist mainly for light vehicles; heavy trucks lean on the depreciation and ZFE channels.

Why the missing toll matters. In the Benelux and Germany, the diesel-electric operating gap is anchored by €0.16–0.30/km of toll differential; in France it rests on energy costs alone — still meaningful (depot electricity versus diesel typically saves €0.10–0.15/km at French tariffs) but slower to amortise the purchase premium. French fleets therefore electrify where the contract demands it (ZFE-exposed urban work, scope-3-driven shipper relationships) rather than where the toll compels it. Watch the political calendar: French debate on CO₂-differentiated HGV charging resurfaces with each finance bill, and any adoption would immediately re-rate the French business case.

WattTonne’s read. French operators should electrify ZFE-exposed and shipper-mandated duty cycles now — the economics work there today — and model the rest of the fleet with a policy-option value: if a French CO₂ toll lands before 2028, early movers will hold the infrastructure (grid connections, depot charging) that latecomers will queue for.
