Understanding Euro VII

The Latest Standard to Reduce Diesel Truck Emissions

The transportation of goods is vital to the global economy, but it comes with a significant environmental impact. Diesel trucks, in particular, are a major contributor to air pollution, accounting for a large proportion of nitrogen oxide (NOx) and particulate matter emissions. To address this, the European Union has implemented a series of measures to reduce the overall emissions profile of diesel trucks. The latest effort to tackle this is through the introduction of Euro VII standards. In this blog post, we will discuss the specifics of Euro VII and its impact on reducing air pollution.

What is Euro VII?

Euro VII is the latest emissions standard for diesel trucks in Europe, which was introduced in December 2020. Its primary focus is on reducing emissions created in urban areas, where air pollution is most severe. The standard aims to further reduce NOx and particulate matter emissions from heavy-duty diesel engines. In addition, Euro VII focuses on improving the effectiveness of Selective Catalytic Reduction (SCR) systems at low temperatures and low speeds.

Why was Euro VII introduced?

The introduction of Euro VII was driven by growing concerns over air pollution in urban areas. Studies have shown that pollutants from diesel vehicles are leading to a rise in health problems such as respiratory diseases, heart attacks, and lung cancer. In addition, air pollution is having a detrimental impact on the environment, contributing to climate change and damaging biodiversity. The aim of Euro VII is to reduce these harmful effects by setting stricter limits on emissions from heavy-duty diesel engines.

How is Euro VII compliance measured?

Measurement of emissions is a critical component of compliance in Euro VII. To ensure compliance, manufacturers will have to retrofit their engines to meet the new standards. One way to measure emissions is through AireCore, a new type of technology that can monitor in real-time NOx emissions at the tailpipe. AireCore provides a more reliable and precise measurement of pollutant emissions, making it easier to determine whether a vehicle complies with the Euro VII standards.

What are the benefits of Euro VII?

The benefits of Euro VII are vast. With the implementation of the new standards, there will be a significant reduction in emissions from heavy-duty diesel engines, leading to a cleaner and healthier environment. The reduction in particulate matter will reduce the number of premature deaths associated with air pollution. In addition, nitrogen oxide emissions cause acid rain, harm crops, and pose a risk to biodiversity. Euro VII's reduction in NOx emissions will, therefore, improve environmental conditions, contributing positively to the fight against climate change.


In conclusion, Euro VII is the latest effort by the European Union to reduce emissions from heavy-duty diesel engines. The new standards specifically focus on improving air quality in urban areas and the effectiveness of SCR systems at low temperatures and low speeds. By measuring emissions using AireCore and other technologies, compliance with Euro VII can be ensured, leading to a cleaner and healthier environment. The introduction of Euro VII will help reduce the negative impact of diesel trucks on the environment and human health, and this is a positive step towards a more sustainable future.
