What is the Euro 7 Emission Standard?

Euro 7 Emission Standard: The Euro 7 emission standard stipulates that nitrogen oxide emissions must not exceed 30 milligrams per kilometer, and carbon monoxide emissions are limited to 100-300 milligrams per kilometer. The relevant introduction to the emission standard is as follows: Introduction to Vehicle Emission Standards: Vehicle emission standards refer to regulations on the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot) emitted from vehicle exhaust. Development Background: With the increasing severity of vehicle exhaust pollution, legislation on vehicle exhaust emissions has become imperative. As early as the 1960s and 1970s, countries around the world established corresponding regulations and systems for vehicle exhaust emissions. Strict regulations have driven the advancement of vehicle emission control technologies, and with the continuous improvement of these technologies, the formulation of higher standards has become possible.
Euro 7 is a new vehicle emissions regulation introduced in Europe, aiming to reduce harmful emissions to even lower levels than the previous Euro 6 standards. It not only regulates common pollutants like nitrogen oxides and particulate matter but also specifically includes overlooked contaminants such as ammonia and formaldehyde. The testing methods have also become more aligned with real-world driving conditions, moving beyond just laboratory simulations—for example, monitoring emission levels during high-speed driving. As someone who enjoys tinkering with cars, I’ve noticed that this might require older gasoline or diesel vehicles to install additional filters to meet the standards, which isn’t cheap. However, it also drives innovation in exhaust treatment technologies, making features like particulate filters smarter. In the long run, it helps reduce urban smog and improve air quality, but car owners should be prepared to spend more on maintenance.
Euro 7 can be considered as a new regulation born to protect the environment, imposing stricter limits on vehicle emissions compared to its predecessor Euro 6. In addition to common pollutants like nitrogen oxides and particulate matter, this time ammonia has also been included in the monitoring list due to its potential to irritate the respiratory system and impact health. The testing process incorporates real-world driving scenarios to ensure more reliable data. I believe this is quite important for daily commuters like us, as reduced pollution means fresher air and potentially fewer cases of childhood wheezing. However, a possible consequence is that new car prices may rise, as automakers need to invest in developing new systems. Overall, it accelerates the automotive industry's shift toward cleaner technologies, such as promoting hybrid vehicles and advancements in battery technology.
