Euro standards are the main way of classifying vehicle emissions. In many countries this information is on the vehicle registration papers - for example in Germany or Denmark. If your vehicle is registered in the UK, ItalyFrance, or the Netherlands, you can check your emissions standard online (see the links). Otherwise, the vehicle age and type will give a guide to its Euro standards, as in the table below. Low emission zones sometimes use vehicles ages where there is no other information available, as it is a good guide to most vehicles Euro standards, particularly for conventionally fuelled cars.

Depending on your vehicle emissions standards, you may or may not be able to enter around 200 cities in 12 countries in Europe with low emission zones. Find out more about which cities you can enter by searching by country or city. Most countries also give cheaper road tax, others give cheaper motorway tolls, congestion charging, parking to cleaner vehicles, or electric vehicles.

Your vehicle may have a different emissions standard to that when it left the factory if the engine has been replaced with a newer engine, or if the vehicle has been fitted with a particulate trap, or converted to an alternative fuel. In these cases you are likely to know that this has happened.

Vehicle Euro Standards

Every 4 to 5 years a new Euro standard has ensured that the vehicles sold have lower emissions. The timings of these standards by vehicle type are given in the table below. This gives a guide to what emissions standard each type of vehicle will be, depending on when it was manufactured. It will only give a guide, as some vehicle models met standards earlier than they were legally required to, and a few small production models were given extensions.

Enhanced environmentally friendly vehicle or EEV is a term used in the European emission standards for the definition of a "clean vehicle" over 3.5 tonne in the category M2 and M3 (i.e. bus and coach). The emission standards for an EEV are between Euro 5 and 6.
