Understanding your vehicle’s emissions standard is essential for compliance with environmental regulations and contributing to cleaner air. The Euro emissions standards, from Euro 1 to Euro 6, have progressively tightened the limits on pollutants emitted by vehicles. This guide provides a comprehensive overview of each standard, helping you determine your vehicle’s classification and its environmental impact.<\/p>\n\n\n\n
The Euro emissions standards are regulations established by the European Union to limit the amount of harmful pollutants released by vehicles. These pollutants include nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Each subsequent Euro standard introduces stricter limits to reduce air pollution and promote public health.<\/p>\n\n\n\n
Introduced in 1992, Euro 1 was the first stage in the EU\u2019s emissions standards, requiring all new cars to be equipped with a catalytic converter to reduce CO, HC, and NOx emissions. Key requirements include:<\/p>\n\n\n\n
Implemented in 1996, Euro 2 further reduced permissible emissions and introduced separate limits for petrol and diesel vehicles:<\/p>\n\n\n\n
Euro 3, which came into effect in 2000, set more stringent standards, particularly for NOx and PM emissions from diesel engines:<\/p>\n\n\n\n
In 2005, Euro 4 introduced significant reductions in diesel particulate emissions and tightened NOx limits for both petrol and diesel vehicles:<\/p>\n\n\n\n
Euro 5, implemented in 2009, marked a significant step by mandating diesel particulate filters (DPFs) to reduce PM emissions drastically:<\/p>\n\n\n\n
Euro 6, introduced in stages from 2014<\/a>, imposed the toughest limits yet, particularly on NOx emissions from diesel vehicles, and included real driving emissions (RDE) testing:<\/p>\n\n\n\n\n
