Euro 6 (emissions standard)

Euro 6 is a European Union regulation that sets strict limits on vehicle emissions, particularly nitrogen oxides (NOx) and particulate matter from diesel and petrol engines. Its goal is to reduce air pollution and protect public health by encouraging cleaner engine technologies and emissions control systems. Vehicles must meet these standards to be sold in the EU, leading manufacturers to adopt advanced filters and catalysts. Euro 6 strikes a balance between environmental responsibility and practical vehicle performance, ensuring new cars emit fewer pollutants while maintaining safety and efficiency standards.
