EURO 6

The Stringent Emission Standard


The Euro 6 emissions standard officially came into force on 1 September 2016, aiming to make vehicles cleaner and greener.

As the name suggests, Euro 6 (also known as EU6 or Euro VI) is the latest round of regulation set by the European Commission governing the amount of harmful exhaust gases motor vehicles can emit. Compared with the previous Euro 5 (also known as EU5 or Euro V) emissions standard, which focused largely on carbon dioxide emissions – the CO2 that is currently used to set road tax bands for cars in the UK (vans are taxed differently) – Euro 6 is particularly targeting nitrogen oxide (NOx) emissions.

But it will also reduce sulphur dioxide, carbon monoxide, hydrocarbon, and diesel particulate matter emissions, as well as CO2

Why Comply?

The EURO 6 standard is designed to reduce harmful pollutants, and for many this will be enough reason. But there are also important financial reasons why meeting this standard is important.

Reduced pollution zones such as the London Ultra Low Emission Zone (ULEZ) and the Clean Air Zones that are being introduced in five other Cities (Birmingham, Derby, Leeds, Nottingham and Southampton) will all require that vehicles entering the zones be EURO 6 compliant in order to avoid substantial daily fees.

The current fee for non-compliant vehicles to enter the existing London LEZ is for HGVs, Buses, Coaches and most other large diesel vehicles. Many in the industry believe that this fee will rise steadily as the public demand ever greater air-quality standards.

From September 2019 with the introduction of the "Ultra Low Emission Zone – ULEZ" in London and September 2020 when the "Clean Air Zones – CAZs" will be introduced in the other cities, diesel powered buses, coaches and heavy goods vehicles (HGVs) will need to meet Euro 6 exhaust emission standards to travel without charge in the zones.

In London if your vehicle does not meet the ULEZ emissions standards and the daily charge is not paid, a Penalty Charge Notice (PCN) will be issued payable by the registered owner or operator. This penalty is in addition to any CC or LEZ penalties received.

For cars, vans and minibuses this will be £130 (reduced to £65 if paid within 14 days). For HGVs, coaches and buses this will be £1,000 (reduced to £500 if paid within 14 days).

Fees payable for non-compliance of the ULEZ standards are over and above those required for LEZ or Congestion Charge.

It is anticipated that financial penalties similar to the London ULEZ will be introduced within the Clean Air Zones – CAZs being setup in the five other cities by 2020

In addition to London's LEZ, a further five 'Clean Air Zones' will be in force in other UK cities within the next 3 years, with a further 10 within the next eight years.

Although the emissions standards for the new Clean Air Zones have not yet been finalised, it is highly likely that they will follow London's example and require EURO 6 as a minimum standard.

Entry to the London LEZ requires EURO 6 compliance to avoid a £200 daily fee (Buses, Coaches, HGVs and most other commercial diesel vehicles)
