Car Pollution Norms - Complete Guide to Euro Standards and Their Impact

Car emissions regulations are a major issue in the modern automotive industry, affecting both manufacturers and consumers. This guide provides a detailed overview of the Euro standards, their evolution and their impact on the automotive market and the environment.

What are car pollution standards and how have they evolved?

Car pollution standards are European regulations designed to limit harmful emissions from motor vehicles. These standards have evolved significantly over time, becoming increasingly stricter to reduce the negative effects of road transport on the environment and public health.

The introduction of the first car pollution standards dates back to 1992, with the advent of the Euro 1 standard. Since then, they have gone through several stages, each bringing more rigorous limits for emissions of pollutants such as nitrogen oxides, carbon monoxide, hydrocarbons and fine particles.

The evolution of Euro standards has been marked by the implementation of advanced emission control technologies. Euro 5, for example, mandated the use of particulate filters for diesel engines, while Euro 6 required selective catalytic reduction systems to control nitrogen oxide emissions.

These standards have had a profound impact on the automotive industry, prompting manufacturers to invest heavily in research to develop more efficient engines and emission control systems. Euro pollution standards have also shaped consumer decisions and public policies, stimulating interest in low- and zero-emission vehicles.

Classification of Euro standards - From Euro 1 to Euro 6

The evolution of Euro standards reflects technological progress and the growing commitment to environmental protection in the automotive sector. Each successive standard has brought significant improvements in reducing pollutant emissions.

Euro 1, introduced in 1992, set the first limits for carbon monoxide and hydrocarbon emissions. Euro 2 (1996) further reduced the limits for CO and introduced restrictions for nitrogen oxides. Euro 3 (2000) separated the limits for hydrocarbons and NOx and imposed significant reductions for all types of emissions.

Euro 4, implemented in 2005, brought substantial reductions in permitted emissions and introduced the first particulate filters for diesel engines. Euro 5 (2009) focused on reducing fine particulate emissions, particularly for diesel engines, by making the use of particulate filters mandatory.

Euro 6, introduced in 2014, is the latest and strictest standard, bringing a dramatic reduction in NOx limits for diesel engines, bringing them closer to those of petrol engines. This norm required the implementation of advanced technologies, such as selective catalytic reduction systems.

How to find out the pollution standard of your car

Identifying your vehicle's pollution standard is essential to understanding its compliance with current regulations and potential traffic restrictions. In Romania, there are two main methods for finding out this information.

The first method involves checking the Vehicle Identity Card (VIC). In the VIC, the Euro standard can be identified in point 6 (National Registration Number) or point 17 (National Emission Code) for new documents, and in point 5 (Homologation Number) for old ones. The specific characters directly indicate the standard, for example, E6 for Euro 6, E5 for Euro 5, and so on.

Alternatively, you can use the "Vehicle History" application on the Romanian Auto Registry (RAR) website. By entering your email address and the chassis number of the car, you will receive a PDF report that includes information about the Euro norm on the registration document.

The impact of the Euro 4 norm on the automotive market

The introduction of the Euro 4 standard in 2005 marked a turning point in the automotive industry, bringing significant changes for both manufacturers and consumers.

For car manufacturers, Euro 4 required substantial investments in emissions reduction technologies. This led to the development of more efficient engines and advanced pollution control systems, such as improved catalytic converters and the first versions of diesel particulate filters.

For buyers, the impact has been a wider choice of Euro 4 cars with lower emissions and improved fuel efficiency, but also higher initial purchase costs. On the second-hand market, Euro 4 compliant vehicles have become preferred, benefiting from less severe traffic restrictions in urban areas with strict environmental policies.

The commercial transport sector was also affected, with companies having to modernise their fleets to remain competitive. An indirect effect of the implementation of the Euro 4 norm was the acceleration of the development of alternative propulsion technologies, with car manufacturers investing more in hybrid vehicles and Euro 4 diesel.

Traffic restrictions based on pollution norms

With increasing concerns about air quality in urban areas, many European cities have implemented traffic restrictions based on pollution norms. of vehicles. These measures have a direct impact on car owners, especially those with older vehicles.

Brussels, for example, has introduced low emission zones (LEZs) that ban diesel vehicles below Euro 4, targeting mainly Euro 2 and older cars. In Germany, restrictions are stricter in some localities, with Stuttgart banning diesel vehicles below Euro 5 in certain areas.

France has adopted a system of labels called Crit'Air, which indicates the vehicle's emissions level and is mandatory for driving in certain urban low-emission zones. This system allows authorities to restrict vehicle access based on the level of air pollution.

In Romania, although there are no general traffic restrictions based on pollution standards yet, there have been discussions about introducing taxes for more polluting vehicles. These restrictions can vary significantly between cities and may change over time, making it essential for vehicle owners to be aware of local regulations.

The future of car pollution standards - Euro 7

Looking ahead, the automotive industry is preparing for the implementation of the Euro 7 standard, which promises to be the strictest and most comprehensive yet. This new standard will significantly expand the scope of automotive emissions regulations.

Euro 7 will address not only tailpipe emissions, but also those from brakes and tires. Proposed measures include limiting nitrogen oxides to 60 mg/km for all combustion engines, making emissions sensors mandatory, and extending the period of compliance with pollution requirements to 10 years or 200,000 km.

The implementation of Euro 7 will have a major impact on the automotive industry, requiring massive investments in research and development. For consumers, this will mean access to cleaner and more efficient vehicles, but possibly with higher purchase and maintenance costs.

In the context of the EU's goal of achieving climate neutrality by 2050, the Euro 7 pollution standards represent an important step towards more sustainable road transport, playing an important role in accelerating the transition to zero-emission mobility and improving air quality in European cities.

Choosing the right vehicle in the context of pollution regulations

Buying a used car is becoming increasingly relevant in the context of new pollution regulations, and choosing a vehicle that complies with current emission standards is essential. To help you make the right and safe choice, in our offer of cars for sale you will find a wide range of carefully checked vehicles, with a clear history and complete documentation. Whether you want a compact city car or a model with premium features at a great price, you will find options that combine modern emission-reducing technologies with an affordable purchase cost.

By choosing a vehicle that meets the latest Euro norms, you not only ensure that you are compliant with current and future regulations, but you also help reduce your carbon footprint and improve the air quality in the community you live in. In addition, a newer vehicle usually offers you better fuel efficiency, which can mean considerable savings in the long run.
