Effect of Euro 7 Standards on Nitrogen Oxide Emissions Across Vehicle Categories

The Euro 7 regulation, set to be implemented in the coming years, has sparked a significant debate within the automotive industry. This regulation, aimed at reducing emissions from vehicles, has been the subject of much discussion due to its potential implications on the transition to a more environmentally friendly transportation system.

The modelling scenario reveals that the Euro 7 regulation has a minimal effect on road transport NOx emissions. This is because the regulation does not significantly contribute to the development of zero-emission vehicles. Instead, it requires substantial diversion of engineering and financial resources, a diversion that may slow down the transition to climate neutrality.

Moreover, the focus on Euro 7 may detract from the development of electrification technologies. The prioritization of Euro 7 could potentially hinder the progress towards a sustainable transportation future. This is particularly concerning given the current initiatives by major automakers such as Mazda and Toyota, who have announced initiatives to strengthen the production and development of zero-emission vehicles.

The modelling scenario considers Euro 7 to be zero-exhaust emissions for cars and vans from 2025, and for heavy-duty vehicles from 2027. However, it is important to note that these standards may not align with the long-term goal of reducing carbon emissions in road transport.

Furthermore, the Sibyl 2020 fleet & emission database lacked information about the ramp-up of zero-emission vehicles, which has been addressed in the modelling. The ACEA's best current estimate of the ramp-up of zero-emission vehicles has been integrated into the modelling.

Investment in Euro 7 has marginal additional environmental benefits. This is because the regulation does not significantly contribute to the development of zero-emission vehicles. Instead, it potentially delays the transition to a more environmentally friendly transportation system.

In conclusion, while the Euro 7 regulation aims to reduce emissions from vehicles, it may not be the most effective strategy for achieving a sustainable transportation future. The diversion of resources from electrification to internal combustion engine engines could potentially hinder progress towards a more environmentally friendly transportation system. It is crucial for policymakers and automakers to consider this when making decisions about the future of the automotive industry.
