Euro 7 emissions standard: from 2027 also for commercial vehicles

Environmental protection is an important topic in today’s world. Exhaust gases play a central role in this, because road traffic is considered the biggest cause of air pollution in cities.

Therefore, exhaust emission standards for commercial vehicles are also an issue of growing importance. In recent years, the European Union (EU) has enacted increasingly stringent emission standards to combat air pollution and climate change. The emission limits for nitrogen oxides and particulates have been significantly reduced. The Euro 6 standard has been in force since 2014 and sets high requirements for reducing emissions. It has made the use of exhaust gas purification systems such as SCR systems (Selective Catalytic Reduction) and diesel particulate filters mandatory for commercial vehicles.

Now the new Euro 7 emissions standard is to replace the currently valid Euro 6/VI standards. From 2025, this will affect passenger cars and vans; from 2027, buses and trucks. The Euro 7 standard is intended to reduce their pollutant emissions and thus contribute to protecting the health of citizens and the environment. It is also intended to keep Europes automotive industry competitive.

In addition to specifications for permissible engine exhaust gases, the new Euro 7 emissions standard also contains upper limits for particulate matter and microplastic emissions as well as emissions from brakes and tyres. And it is precisely these emissions that represent the largest sources of emissions in electric vehicles. Given the growing market share of CO2free vehicles, the Euro 7 standard will also be of great importance here. Emissions from tyres, which are among the biggest contributors to microplastics in the environment, will also be minimised in this way.

The Euro 7 standard regulates emission limits for all motor vehicles and is fuel and technology neutral. The same limit values apply regardless of the fuel or the drive of the vehicle.

The EU Commission wants to strengthen consumer confidence in electric vehicles and promote the transition to a climateneutral, resourceconserving and emissionfree economy. The nitrogen oxide limits for cars and vans are also to be reduced by 2035 more so for trucks and buses than for cars and vans. In addition, gases that have not been covered so far are to be regulated, for example ammonia or nitrous oxide for heavyduty vehicles. In this way, means of transport should become significantly more environmentally friendly, especially in cities.

All this means that the manufacturers of commercial vehicles will have to optimise and adapt their engines and exhaust gas purification systems. This in turn naturally leads to higher costs and longer development times, which has an impact on the entire supply chain. Component suppliers must also adapt their products to the new standards and adjust to the changed requirements.

However, the increased demands on component manufacturers and suppliers are not only due to the new Euro 7 standard, but mainly to the increasing public debate about pollution and climate change. The demand for environmentally friendly and lowemission commercial vehicles is expected to increase further in the coming years. The automotive industry must respond to these developments and develop innovative solutions for sustainable mobility. Some manufacturers are already using alternative forms of propulsion such as electric motors or fuel cells to reduce emission levels. Suppliers must be able to support these new technologies and provide corresponding components. The development of customised solutions and cooperation with customers are crucial here. In the commercial vehicle sector, research and development is moving towards more environmentally friendly and sustainable solutions.

Electrification and the use of hydrogen as a drive source are becoming increasingly important. To support the switch to alternative drives, the expansion of the infrastructure is also being driven forward. More and more charging stations and hydrogen filling stations are being built to enable the operation of electric and hydrogen vehicles. In addition, new technologies and materials are being developed to improve the efficiency of commercial vehicles and reduce fuel consumption. One example is the aerodynamic design of truck cabs, which reduces air resistance and thus lowers fuel consumption.

Cooling and airflow also remain critical, regardless of the powertrain solution, and can contribute to dramatic improvements in any powertrain technology.

Suppliers and subsuppliers must therefore currently react with great flexibility. This means that manufacturers must not only meet the new EU standards, but also the needs of their customers. Many have already integrated environmental protection and sustainability goals into their company policies and are striving to achieve them. Manufacturers and suppliers must therefore now work much more closely with the customer. In the course of constant further development, it is important to offer individual solutions. Together with the customer, requirements and needs must be understood, recorded and analysed in a futureoriented way. Then possible solutions are explained and discussed. In this process, expert advice from experts is extremely important. Through forwardlooking planning, an optimal and sustainable solution can be worked out together, which can lead to extensive cost savings in the long run.
