Carbon monoxide (CO) Hydrocarbons (HC) Nitrogen oxides (NOx) Particulate matter (PM)  Euro 1 (EC93)Applies to all new cars registered from 1 January 1993 Benefits: The Euro 1 standard heralded the introduction of catalytic converters and unleaded petrol for all cars. Euro 1 emissions limits (petrol) CO: 2.72g/km HC + NOx: 0.97g/km Euro 1 emissions limits (diesel) CO: 2.72g/km HC + NOx: 0.97g/km PM: 0.14g/km Euro 2 (EC96)Applies to all new cars registered from 1 January 1997 Benefits: Euro 2 standards introduced different emissions limits for petrol and diesel engines and reduced the acceptable levels of all four major emissions across the board. Euro 2 emissions limits (petrol) CO: 2. 20g/km HC + NOx: 0.50g/km Euro 2 emissions limits (diesel) CO: 1.00g/km HC + NOx: 0.70g/km PM: 0.08g/km Read more – Diesel cars to be charged more for driving in LondonEuro 3 (EC2000)Applies to all new cars registered from 1 January 2001 Benefits: Introduced separate limits for hydrocarbons and nitrogen oxide emissions for petrol engines, and a separate nitrogen oxide limit for diesel engines.

Some new diesel-engined cars gained diesel particulate filters (DPFs) that trap 99% of particulates. Euro 4 emissions limits (petrol) CO: 1.00g/km HC: 0.10g/km NOx: 0.08g/km Euro 4 emissions limits (diesel) CO: 0.50g/km HC + NOx: 0.30g/km NOx: 0.25g/km PM: 0.025g/km |
