On 30 March 2026 the Council of the EU adopted the amendment to Regulation (EU) 2019/1242 that the industry had spent a year lobbying for: the −15% CO₂ reduction target for new heavy-duty vehicles, originally designed as a 2025 milestone stepping upward every five years, is now frozen through 2029. From 2030 the target jumps to −45% and holds to 2034, before the previously agreed −65% (2035) and −90% (2040) steps.

The truck makers’ argument was utilisation of the interim years: with electric trucks at under 5% of registrations, an upward ratchet in the late 2020s would have forced compliance costs into a market whose charging infrastructure is still under construction. The Parliament and Council bought the logic — with the explicit trade that 2030 becomes the hard cliff.

For fleet buyers, the amendment changes the calendar but not the direction, and it creates three practical consequences. First, diesel availability is safe through the decade — no manufacturer will be forced to ration diesel tractors before 2029, so there is no supply-panic reason to buy electric early. The reasons to buy early are economic: toll gaps and grants, which we track in Subsidy Watch. Second, from 2030 manufacturers must sell large volumes of zero-emission trucks — roughly a third or more of new sales by most estimates — or pay excess-emission penalties. That creates a seller’s market in reverse: expect aggressive electric pricing, financing packages and trade-in guarantees as 2030 approaches, and expect diesel residuals to face a structural headwind as fleets anticipate the shift. Third, the amendment signals regulatory stability. The 2030–2034 plateau at −45% gives finance departments a fixed compliance wall to model against rather than a moving one.

One nuance worth board attention: the −45% target applies to manufacturers’ fleet-average sales, not to your fleet. Nobody will force your company to buy an electric truck in 2030. But the CO₂-graded tolls, low-emission zones and customer scope-3 requirements that push you toward electric are all being built on the same legislative foundation — and none of them moved with the staircase. The demand-side pressure is intact; only the supply-side timetable was softened.

What to do with this

Model two procurement waves, not one: suitable duty cycles now (toll-exposed, depot-based), and the rest of the fleet against the 2029–2031 window when manufacturer pricing pressure peaks and charging build-out matures. Fleets that wait for 2030 to start learning will pay tuition at the worst possible time.
