Euro 6 emissions requirements: what do they imply for you?
Environmental air pollution has had a big affect on the world. Years in the past, producers would produce automobiles that delivered greater and higher efficiency, paying little regard to the pollution given off by the automobiles. Nonetheless, as atmospheric research have revealed an increase in pollution within the air, governments and legislative our bodies throughout the globe have clamped down on automobile emissions to assist scale back it.
In Europe, the European Union’s motion to curb air pollution from automobiles has taken the type of the Euro emissions requirements and the newest within the line that started in 1993 with Euro 1 is Euro 6. If automobile producers wish to promote a automobile in Europe immediately, it has to satisfy the Euro 6 emissions requirements on the official checks.
After all, it’s nowhere close to so simple as that, Euro 6 and the emissions requirements earlier than it have performed a serious function within the form of the automobile market by pushing automobile makers to supply cleaner automobiles and Governments to construct automobile taxation methods across the requirements. Even the checks themselves have come underneath scrutiny and been up to date to supply a greater image of real-world emissions ranges.
This information rounds up the newest Euro 6 emissions requirements and testing procedures, and we additionally clarify the brand new laws to enhance emissions testing regulation and assist keep away from automobile makers short-cutting the checks.
How are new automobiles examined for emissions?
To make emissions checks extra reflective of real-world driving, new WLTP (World harmonised Gentle automobile Testing Protocol) checks have been launched in September 2018 to switch the previous NEDC checks.
All new automobiles at the moment are offered after WLTP testing to extra intently replicate gasoline economic system and emissions when really driving, and embody an extra real-world driving emissions (RDE) take a look at to detect regulated pollutant emissions. The RDE is to be carried out on the highway as a substitute of the lab, and can use a transportable emissions measurement system to file emissions.
The process is carried out in a managed setting, and checks are witnessed by Authorities companies. The ambient temperature, automobile fluid ranges and tyre pressures are all measured to take care of consistency between checks of various fashions, and this ensures the take a look at is as correct as doable. Meaning all automobiles are examined in the identical circumstances and signifies that the emissions figures recorded for them will be in contrast instantly to one another once you’re evaluating specs between automobiles.
The automobiles which can be chosen for the take a look at are randomly chosen from the manufacturing strains by the legislative physique. Meaning the producer cannot provide a specifically ‘tweaked’ mannequin that could possibly be optimised to supply beneficial outcomes.
Nonetheless, as Volkswagen proved, automobile makers can nonetheless bypass these laws with out doctoring a take a look at mannequin.
What’s Euro 6?
Euro 6 is the sixth incarnation of the European Union directive to scale back dangerous pollution from automobile exhausts. The Euro 6 commonplace was launched in September 2015, and all mass-produced automobiles offered from this date want to satisfy these emissions necessities. The purpose of Euro 6 is to scale back ranges of dangerous automobile and van exhaust emissions, each in petrol and diesel automobiles.
This contains nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons (THC and NMHC) and particulate matter (PM), which is mainly soot from diesel automobiles. The knock-on impact of lowering these pollution also can imply improved gasoline economic system and decrease CO2 emissions.
NOx is a dangerous pollutant that’s usually blamed for damaging the setting, and has additionally been confirmed to have critical well being implications. Particulate matter, in the meantime, is a neighborhood pollutant that has additionally been linked to well being and respiratory issues. A date for the introduction of the Euro 7 requirements has but to be set and a few governments and automobile makers are nonetheless adjusting to the calls for of Euro 6.
Euro 6 laws set completely different emissions requirements for petrol and diesel automobiles, however that may be a reflection of the completely different sorts of pollution the 2 fuels produce. For diesels, the permitted stage of NOx emitted has dramatically dropped to a most of 80mg/km, in comparison with the 180mg/km stage that was required for automobiles that met the earlier Euro 5 emissions commonplace. In distinction, the NOx restrict for petrol automobiles remained unchanged from Euro 5, because it was already low at 60mg/km.
Diesel automobiles and the Euro 6 emissions requirements
Older diesel automobiles that produce greater ranges of NOx and particulate matter have been underneath fireplace from quite a few environmental teams for a couple of years now. The UK Authorities has been blamed for engaging shoppers into diesel automobiles, that are thought of to be extra environmentally dangerous, with highway tax and firm automobile tax buildings that profit low CO2 emissions.
The highway tax argument is now null, as a result of the Authorities launched a brand new highway tax construction in 2017, whereas the automotive business and the Society of Motor Producers and Merchants (SMMT) that represents it have come out in defence of diesel automobiles and began a marketing campaign to lift consciousness of the clear diesel know-how fitted to Euro 6-compliant fashions.
The SMMT is trying to make sure all diesel automobiles aren’t tarred with the identical brush, and is drawing a line between older diesels and the brand new era of unpolluted diesel fashions. The priority is that confusion may lead consumers to snub the newer Euro 6 diesels once they ship comparable air pollution discount because the petrol options.
Euro 6 and ULEZ extremely low emissions zones
The longer-term future for diesel automobiles appears to be like slightly extra unsure for the explanations touched on above. Regardless that a lot of the criticism of diesel automobiles is misplaced, there are important monetary penalties for homeowners of diesel automobiles and these might improve in future.
The ULEZ (Extremely Low Emissions Zone) in London is a levy for drivers of the best polluting automobiles in central London. It covers the identical space as London’s Congestion Cost Zone, however it’ll increase to cowl all areas contained in the North and South Round from 26 October 2021.
The automobiles which can be affected by ULEZ are usually pre-Euro 6 diesels (ones constructed earlier than round 2016) and pre-Euro Four petrols (constructed earlier than round 2006). The usual day by day ULEZ charge is £12.50 – coupled with the additionally obligatory Congestion Cost of £11.50, the whole value of some automobiles to enter the centre of London will probably be as much as £24.
Some councils additionally began to cost homeowners of diesel automobiles extra for parking permits. Islington council in London launched a surcharge of £120 from April 2019 for anybody with a diesel automobile (excluding residents with Blue Badges, and residents who rely on their automobile for employment functions). It claims that the reasoning behind that is “to guard residents from the well being dangers related to diesel emissions”.
Euro 1 to Euro 6: European emissions laws timeline
European emission requirements first got here into power in 1993, with Euro 1 requirements turning into regulation. This preliminary commonplace ensured that diesel automobiles emitted not more than 780mg/km of nitrogen oxide, whereas the utmost for petrol engines was 490mg/km.
This moved on to Euro 2 in 1997 that dropped diesel NOx to 730mg/km and Euro Three requirements adopted in 2001 decreasing the diesel NOx restrict to 500mg/km. By 2006, Euro Four emissions have been in place lowering the utmost NOx in diesels to 250mg/km and Euro 5 lowered it additional to 180mg/km in 2011.
All through this time, the utmost quantity of NOx emitted by diesel automobiles has been nicely behind that of petrol fashions. Below Euro 6 requirements, nonetheless, the utmost stage for NOx in diesel fashions is 80mg/km, in comparison with 60mg/km in petrol automobiles.

The tables beneath exhibits the Euro emissions requirements for diesel and petrol automobiles. The dates when the requirements have been launched may give a great indication of the emissions commonplace that your diesel automobile conforms to. In case your automobile was first registered after the date when the Euro commonplace got here into power then there is a good probability it conforms to that commonplace. Nonetheless, you need to at all times test together with your automobile’s producer in case you are in any doubt as a result of fashions that conform to the requirements are sometimes offered earlier than the date of its introduction and fashions that do not meet the usual are typically registered after that date.
