The Euro 7 emission standard is a stricter regulation following Euro 6. Its goal is to control pollution from engines. This standard aims to reduce negative impacts on the environment and human health.
Definition of Euro 7 and Comparison with Euro 6
The Euro 7 emission standard is the latest regulation issued by the European Union to limit the amount of motor vehicle pollutants. Euro 7 will replace Euro 6, which has been in effect since 2014. The main difference between Euro 7 and Euro 6 lies in the stricter emission limits and broader regulatory scope. Euro 6 focused on limiting nitrogen oxide (NOx) and particulate matter (PM) emissions, while Euro 7 will expand its scope to include other pollutants such as ammonia (NH₃) and non-exhaust particulate matter, which results from tire and brake friction. In addition, Euro 7 will apply stricter emission limits to all types of vehicles, including gasoline cars, diesel, hybrid, and even electric vehicles.
Emission Regulations and Limits in Euro 7
Euro 7 not only tightens emission limits but also introduces more realistic testing methods. Unlike Euro 6, which relied on laboratory testing, Euro 7 will use emissions testing under everyday driving conditions (Real Driving Emissions, RDE). This aims to ensure that vehicles meet emission standards not only in the laboratory but also on the road. Some of the proposed emission limits in Euro 7 include:
- NOx (Nitrogen Oxides): The maximum allowable limit will be significantly reduced, especially for diesel vehicles.
- CO (Carbon Monoxide): CO emission limits will be tightened for all vehicle types.
- Particulates: Euro 7 will limit fine particulates (PM2.5) generated from brakes and tires.
- Ammonia (NH₃): For the first time, ammonia emissions will be regulated, especially for gasoline vehicles.
In addition, Euro 7 will also introduce new requirements regarding the durability of emission control components, such as catalysts and particulate filters, which must remain effective up to a certain mileage.

Challenges in Euro 7 Implementation
While Euro 7 is considered a step forward in reducing vehicle emissions, the regulation is not without its challenges. One of the main challenges is the high cost of implementation. Vehicle manufacturers will have to make large investments to develop new technologies and modify production processes. This cost will likely be passed on to consumers in the form of higher vehicle prices. Another challenge is that the implementation time is too short and the automotive industry is in the transition stage of the new standard. Countries that have not yet implemented Euro 6 may also experience difficulties in immediately adapting to Euro 7, especially in terms of infrastructure and policies.
Euro 7 emission standards mark a new chapter in global efforts to reduce air pollution and protect the environment. With stricter emission limits and more realistic testing methods, these regulations are expected to bring positive changes. However, the challenges and criticisms that have emerged cannot be ignored. The automotive industry must adapt quickly, while the relevant governments need to ensure that the transition is fair and sustainable. Ultimately, the success of Euro 7 depends not only on the compliance of vehicle manufacturers, but also on the support of various parties, including the government, consumers, and society at large. With good collaboration, these emission standards can be an important step towards a cleaner and greener future.
