NOx emissions from the EU heavy truck fleet by Euro classes

NOx emissions from the EU heavy truck fleet by Euro classes

ACEA — 2023-01-20

News from Brussels

Figures show that in 2025 Euro VI heavy trucks will make up almost 58% of the EU fleet. However, pre-Euro VI vehicles (sold before 2013) will still contribute to 77% of total NOx emissions from the heavy truck fleet.

At the same time – as shown here – Euro VII for heavy trucks is expected to have only a marginal impact on NOx emissions’ reduction. Moreover, a massive investment in Euro VII, would also divert substantial engineering and financial resources from battery and fuel-cell electric technologies back to the internal combustion engine.

This means that fleet renewal targeting the large numbers of pre-Euro VI heavy trucks on EU roads would have the greatest impact on both pollutant and CO2.

Modelling assumptions

According to the Sibyl modelling scenario, Euro 7 is considered to be zero-exhaust emissions from 2025 (cars and vans) and zero-exhaust emission from 2027 (heavy-duty vehicles). ACEA’s best current estimate of the ramp-up of zero emission vehicles (from latest OEM announcements and assumptions regarding possible future CO2 targets) has been integrated into the modelling because the Sibyl 2020 fleet & emission database lacked such information.
