European truck manufacturers are seeking a two-year delay to Euro 7 emissions rules for heavy-duty vehicles, raising questions over the timetable Irish hauliers should use when planning fleet replacements.

The European Automobile Manufacturers’ Association (ACEA) has also requested a separate five-year postponement of heavy-duty brake-emission requirements.

In a statement published on 20 October, ACEA said it had written to Members of the European Parliament seeking additional time to prepare for the new standards. It argues that key testing procedures and methods for assessing compliance have yet to be finalised and sufficiently validated.

Current deadlines remain in place

The manufacturers’ request does not change the existing legislation.

Under the current Euro 7 timetable, the requirements apply to new truck types from 29 May 2028, followed by all new trucks from 29 May 2029, subject to the regulation’s specific exceptions.

The first deadline concerns newly approved vehicle designs. The second generally covers the registration, sale and entry into service of new vehicles, including models based on previously approved designs.

A two-year postponement, if adopted as requested, would move those milestones to May 2030 and May 2031. For now, operators should continue to use the legislated dates when discussing future orders with suppliers.

Brake testing at the centre of concerns

ACEA says manufacturers and suppliers need more time to develop and validate reliable testing methods across the different categories of heavy-duty vehicles and braking systems.

It warns that uncertainty over the technical framework has implications for vehicle development, safety validation, production planning and investment.

The association argues that a more realistic timetable would provide regulatory certainty while preserving Euro 7’s environmental objectives. These are the manufacturers’ stated concerns, rather than an EU decision to postpone implementation.

Euro 7 reaches beyond the exhaust

Euro 7 broadens the scope of vehicle emissions regulation to include brake particles and tyre abrasion, alongside exhaust emissions and battery durability.

For heavy trucks, it introduces tighter limits on pollutants and longer requirements for emissions performance to remain effective over a vehicle’s working life. The framework therefore also has relevance for electric vehicles, which still produce emissions through tyre and brake wear.

The tyre timetable is separate from the main truck deadlines. New types of C3 tyres, generally used on heavy trucks and trailers, come within the regulation’s application timetable from 1 April 2032.

What it means for Irish hauliers

For Irish fleet operators, the immediate issue is purchasing certainty. Businesses considering replacement trucks around 2028–29 need to know which specifications manufacturers will offer, when vehicles can be delivered and registered, and how warranty and maintenance packages will compare.

A changed timetable could affect model introduction and ordering decisions. However, the request alone provides no reliable basis for predicting vehicle price changes or delaying an otherwise necessary replacement.

Euro 7’s new-vehicle deadlines do not themselves require existing Euro VI trucks to be withdrawn or upgraded. Operators should assess those vehicles on condition, reliability, operating costs and the requirements of the work they undertake.

Hauliers placing orders for delivery near the transition should seek written confirmation of the vehicle’s emissions specification and expected registration date. Until an amendment becomes law, the May 2028 and May 2029 deadlines remain the dates to plan around.
