Along with emissions standards, the European Union has also mandated a number of computer [[on-board diagnostics]] for the purposes of increasing safety for drivers. These standards are used in relation to the emissions standards.<ref>{{Cite journal |last=OECD |date=2009 |title=Effects of environmental policy on the type of innovation: the case of automotive emission-control technologies |url=https://www.oecd.org/content/dam/oecd/en/publications/reports/2010/01/oecd-journal-economic-studies-volume-2009_g1gh991c/eco_studies-v2009-1-en.pdf? |journal=OECD Journal: Economic Studies |volume=2009 |pages=57–59}}</ref>
During the early 2000s, [[Australia]] began [[Harmonisation of law|harmonising]] [[Australian Design Rule]] certification for new motor vehicle emissions with Euro categories. Euro III was introduced on 1 January 2006 and is progressively being introduced to align with European introduction dates.

The stages are typically referred to as Euro 1, Euro 2, Euro 3, Euro 4, Euro 5, Euro 6 and Euro 7 for Light Duty Vehicle standards.
The legal framework consists in a series of directives, each amendments to the 1970 Directive 70/220/EEC.{{r|Europa 3}} The following is a summary list of the standards, when they come into force, what they apply to, and which EU directives provide the definition of the standard. * '''Euro 1''' (1992): ** For passenger cars—91/441/EEC.{{r|Eur-lex 2}} ** Also for passenger cars and light lorries—93/59/EEC. * '''Euro 2''' (1996) for passenger cars—94/12/EC (& 96/69/EC) ** For motorcycle—2002/51/EC (row A){{r|Eur-lex 3}}—2006/120/EC * '''Euro 3''' (2000) for any vehicle—98/69/EC{{r|Eur-lex 4}} ** For motorcycle—2002/51/EC (row B){{r|Eur-lex 3}}—2006/120/EC * '''Euro 4''' (2005) for any vehicle—98/69/EC (& 2002/80/EC) * '''Euro 5''' (2009) for light passenger and commercial vehicles—715/2007/EC{{r|Eur-lex 5}} * '''Euro 6''' (2014) for light passenger and commercial vehicles—459/2012/EC{{r|Eur-lex 9}} and 2016/646/EU{{r|Eur-lex 10}} * '''Euro 7''' (2026) for light- and heavy-duty vehicles—2024/1257/EU{{r|Eur-lex 11}}
These limits supersede the original directive on emission limits 70/220/EEC.
The classifications for [[vehicle category]] are defined by:{{r|Europa 6}} * Commission [[Vehicle category#EU classification|Directive 2001/116/EC]] of 20 December 2001, adapting to technical progress Council Directive 70/156/EEC on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers{{r|Eur-lex 6}}{{r|Eur-lex 7}} * Directive 2002/24/EC of the European Parliament and of the Council of 18 March 2002 relating to the type-approval of two or three-wheeled motor vehicles and repealing Council Directive 92/61/EEC
===Emission standards for passenger cars=== Emission standards for [[passenger cars]] and [[Light commercial vehicle|light commercial vehicles]] are summarized in the following tables. Since the Euro 2 stage, [[EU regulations]] introduce different emission limits for diesel and petrol vehicles. Diesels have more stringent CO standards but are allowed higher {{NOx}} emissions. Petrol-powered vehicles are exempted from particulate matter (PM) standards through to the Euro 4 stage, but vehicles with [[Direct fuel injection|direct injection]] engines are subject to a limit of 0.0045 g/km for Euro 5 and Euro 6. A particulate number standard (P) or (PN) has been introduced in 2011 with Euro 5b for diesel engines and, in 2014, with Euro 6 for petrol engines.<ref>{{cite press release |url=http://www.psa-peugeot-citroen.com/sites/default/files/content_files/les-moteurs-diesel-elimination-des-particules.pdf |title=Élimination des particules |first1=Pierre |last1=Macaudière |first2=Nils |last2=Matthess |page=6 |publisher=PSA Peugeot Citroen |date=January 2013 |access-date=23 September 2015 |url-status=dead |archive-url=https://web.archive.org/web/20170119023416/http://www.psa-peugeot-citroen.com/sites/default/files/content_files/les-moteurs-diesel-elimination-des-particules.pdf |archive-date=19 January 2017}}</ref><ref name=DN-Standards>{{cite web |url=https://www.dieselnet.com/standards/eu/ld.php |title=Emission Standards » European Union » Cars and Light Trucks |publisher=DieselNet |date=January 2015 |access-date=23 September 2015}}</ref><ref name=eurlex715>{{cite web |url=http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2007:171:0001:0016:EN:PDF |title=Regulation (EC) No 715/2007 |publisher=The European Parliament and the Council of the European Union |pages=5–9 |date=20 June 2007 |access-date=29 October 2015}}</ref>
From a technical perspective, European emissions standards do not reflect everyday usage of the vehicle as manufacturers are allowed to lighten the vehicle by removing the back seats, improve aerodynamics by taping over grilles and door handles, or reduce the load on the generator by switching off the headlights, the passenger compartment fan, or simply disconnecting the [[alternator]] which charges the battery.<ref name=nytimes_23sep2015>{{cite news|title=Volkswagen Test Rigging Follows a Long Auto Industry Pattern|url=https://www.nytimes.com/2015/09/24/business/international/volkswagen-test-rigging-follows-a-long-auto-industry-pattern.html|access-date=17 November 2015|work=The New York Times|date=23 September 2015}}</ref>

===Emission standards for motorcycles (two- and three-wheelers) - Category L=== The Euro emissions regulations for two- and three-wheelers (motorcycles) were first introduced in 1999 — some seven years after the cars were first regulated. In further difference to passenger cars (where three-way catalytic converters were de facto required from Euro I), it was first with the introduction of the Euro III emissions standard in 2006 that motorcycles were de facto required to use three-way catalytic converters. With the introduction of Euro V, standard two-stroke engine motorcycles are challenged by the strict HC and PM emissions limits. It is expected that technologies such as direct injection, combined with petrol particulate filters, could be needed for these [[motorcycle engine]] types to meet the Euro V demands.<ref>{{cite news|url=https://www.infineuminsight.com/en-gb/articles/small-engines/euro-5-motorcycles/|title=Euro 5 motorcycles, Euro 5 emissions legislation could mean the disappearance of two-stroke engines |language=en |newspaper= Infineum International Limited |date=14 August 2018 |access-date=26 September 2021}}</ref><ref>{{cite news|url=https://www.aecc.eu/legislation/motorcycles-and-mopeds/|title=History of motorcycle emmissions standards |newspaper= AECC (the Association for Emissions Control by Catalyst) |date=14 August 2018 }}</ref><ref>{{cite news|url=https://circabc.europa.eu/sd/a/6d2b9e86-543f-42be-84f7-dd0a32969d01/report_measures_motorcycle_emissions_en.pdf|title=Study on possible new measures concerning motorcycle emissions |language=en |pages=44–45 |newspaper= The Laboratory of Applied Thermodynamics Department of Mechanical Engineering Aristotle University of Thessaloniki |date=1 September 2009 |access-date=20 October 2021}}</ref>

The emission standards for trucks (lorries) and buses are defined by engine energy output in g/[[kilowatt hour|kWh]]; this is unlike the emission standards for passenger cars and light commercial vehicles, which are defined by vehicle driving distance in g/km — a general comparison to passenger cars is therefore not possible, as the kWh/km factor depends, among others, on the specific vehicle.
The official category name is heavy-duty diesel engines, which generally includes lorries and buses.
The following table contains a summary of the emission standards and their implementation dates. Dates in the tables refer to new type approvals; the dates for all new registrations are in most cases one year later.

===Emission standards for non-road mobile machinery=== The term ''[[non-road mobile machinery]]'' (NRMM) is a term used in the European emission standards to control emissions of engines that are not used primarily on public roadways. This definition includes [[off-roading|off-road]] vehicles as well as [[railway vehicle]]s.
European standards for non-road diesel engines harmonise with the [[United States emission standards|US EPA standards]], and comprise gradually stringent tiers known as Stage I–V standards. The Stage I/II was part of the 1997 directive (Directive 97/68/EC). It was implemented in two stages, with Stage I implemented in 1999 and Stage II implemented between 2001 and 2004. In 2004, the European Parliament adopted Stage III/IV standards. The Stage III standards were further divided into Stage III A and III B, and were phased in between 2006 and 2013. Stage IV standards are enforced from 2014. Stage V standards are phased in from 2018 with full enforcement from 2021.
As of 1 January 2015, EU Member States have to ensure that ships in the Baltic, the North Sea and the [[English Channel]] are using fuels with a sulphur content of no more than 0.10%. Higher sulphur contents are still possible, but only if the appropriate exhaust cleaning systems are in place.<ref>{{cite web |url=http://ec.europa.eu/environment/air/transport/ships.htm |title=Transport & Environment – Emissions from Maritime Transport |publisher=European Commission |date=16 February 2015 |access-date=28 February 2015}}</ref>
== Emission test cycle == {{update section|date=September 2020}}
Just as important as the regulations are the tests needed to ensure adherence to regulations. These are laid out in standardised [[emission test cycle]]s used to measure emissions performance against the regulatory thresholds applicable to the tested vehicle.
=== Light duty vehicles === Since the Euro 3 regulations in 2000, performance has been measured using the [[New European Driving Cycle]] test (NEDC; also known as MVEG-B), with a "[[Cold start (automotive)|cold start]]" procedure that eliminates the use of a 40-second engine warm-up period found in the ECE+EUDC test cycle (also known as MVEG-A).<ref name=DN-Standards /><ref name="DN-Cycles">{{cite web | url=https://www.dieselnet.com/standards/cycles/ece_eudc.php | title=Emission Test Cycles: ECE 15 + EUDC / NEDC | publisher=DieselNet | date=July 2013 | access-date=28 September 2015}}</ref> Since 2017 the NEDC was replaced by the Worldwide harmonized Light vehicles Test Procedure (WLTP).<ref>{{Cite web |last=Kroher |first=Thomas |date=2024-03-05 |title=WLTP statt NEFZ: So funktioniert das aktuelle Messverfahren |url=https://www.adac.de/rund-ums-fahrzeug/autokatalog/abgasnormen/wltp-messverfahren/ |access-date=2024-12-06 |website=ADAC, Allemeiner Deutscher Automobil Club}}</ref> === Heavy duty vehicles === The two groups of emissions standards for heavy duty vehicles each have different appropriate test requirements.

=== "Cycle beating" controversy {{anchor|Cycle beating}} === [[File:NOx Diesel emissions - real vs Euronorms.svg|thumb|Comparison between emission standards for nitrogen oxides (NOx) of diesel cars and measured emissions<ref>{{Cite web|url=https://www.eea.europa.eu/media/infographics/comparison-of-nox-emission-standards/view|title=Comparison of NOx emission standards for different Euro classes|date=27 January 2016 |publisher=European Environment Agency|language=en|access-date=7 March 2019}}</ref>]]
For the emission standards to deliver actual emission reductions, it is crucial to use a test cycle that reflects real-world driving conditions. It was discovered<ref>{{cite web|url=http://www.transportenvironment.org/publications/dont-breathe-here-tackling-air-pollution-vehicles | title=Don't Breathe Here: Tackling air pollution from vehicles |website=Transport Environment| date=14 September 2015| access-date=13 October 2015}}</ref> that vehicle manufacturers would optimise emissions performance only for the test cycle, whilst emissions from typical driving conditions proved to be much higher than when tested. Some manufacturers were also found to use so-called ''[[defeat device]]s'' where the engine control system would recognise that the vehicle was being tested, and would automatically switch to a mode optimised for emissions performance. The use of a defeat device is expressly forbidden in EU law.<ref name=eurlex715/>
An independent study in 2014 used portable emissions measurement systems to measure {{NOx}} emissions during real world driving from fifteen Euro 6 compliant diesel passenger cars. The results showed that {{NOx}} emissions were on average about seven times higher than the Euro 6 limit.

===Obligatory labelling=== The purpose of ''Directive 1999/94/EC of the European Parliament and the Council of 13 December 1999 relating to the availability of consumer information on fuel economy and {{CO2}} emissions in respect of the marketing of new passenger cars''{{r|Eur-lex 8}} is to ensure that information relating to the [[Fuel economy in automobiles|fuel economy]] and {{CO2}} emissions of new passenger cars offered for sale or lease in the Community is made available to consumers in order to enable consumers to make an informed choice.
In the United Kingdom, the initial approach was deemed ineffective. The way the information was presented was too complicated for consumers to understand. As a result, car manufacturers in the United Kingdom voluntarily agreed to put a more "consumer-friendly", colour-coded label displaying {{CO2}} emissions on all new cars beginning in September 2005, with a letter from A (<100 {{CO2}} g/km) to F (186+ {{CO2}} g/km). The goal of the new "green label" is to give consumers clear information about the environmental performance of different vehicles.{{r|WeatherVane}}
Other EU member countries are also in the process of introducing consumer-friendly labels.
{{anchor|Obligatory vehicle CO2 emission limits}}
===Obligatory vehicle {{CO2}} emission limits=== [[Directive (European Union)|European Union Directive No 443/2009]] set a mandatory average fleet {{CO2}} [[emissions target]] for new cars, after a voluntary commitment made in 1998 and 1999 by the auto industry had failed to reduce emissions by 2007. The regulation applies to new passenger cars registered in the [[European Union]] and [[European Economic Area|EEA]] member states for the first time. A carmaker who fails to comply has to pay an "excess emissions premium" for each vehicle registered according with the amount of g/km of exceeded.<ref name="443/2009">{{cite web| url=https://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:140:0001:0015:EN:PDF | title=Regulation (EC) No 443/2009 of the European Parliament and of the Council |publisher=Official Journal of the European Union | date=23 April 2009 | access-date=22 June 2020}}</ref>

The 2009 regulation set a 2015 target of 130 g/km for the fleet average for new passenger cars. A similar set of regulations for [[light commercial vehicle]]s was set in 2011, with an emissions target of 175 g/km for 2017.

'''Specific emissions targets for passenger cars'''
To account for different sizes of passenger cars, the specific emissions target for each passenger car is calculated by adjusting the general emissions target by a value proportional to the deviation of the car's mass from the average. This means that the emissions targets for heavier cars are higher than those for lighter cars. In Regulations (EC) 443/2009 and (EU) 2019/631 this relationship between the specific emissions target {{math|''E''}} and the general emissions target {{math|''E''<sub>0</sub>}} is expressed as {{math|''E'' {{=}} ''E''<sub>0</sub> + ''a'' × (''M''-''M''<sub>0</sub>)}} with the mass of the specific vehicle denoted by {{math|''M''}} and the average vehicle mass denoted by {{math|''M''<sub>0</sub>}} (approx. {{cvt|1400|kg|lbs}}). The Regulations determine the factor {{math|''a''}} as 0.0457 for 2012–2019 and as 0.0333 from 2020 onward.<ref name="443/2009" /><ref name="2019/631" />
'''Pooling'''
Two or more car manufacturers may form a pool which allows them to meet fleet targets as a group instead of having to meet them individually. The first pool was agreed among Tesla and Fiat Chrysler in 2019, reportedly costing Fiat Chrysler hundreds of millions of Euros.<ref>{{cite web |title=Fiat Chrysler to pay Tesla hundreds of millions of euros to pool fleet |url=https://www.reuters.com/article/us-fiat-chrysler-tesla-eu-idUSKCN1RJ03I |work=Reuters |access-date=12 January 2023 |date=7 April 2019}}</ref>
'''ZLEV Credit System'''
The 2019 Regulation also introduced an incentive mechanism or credit system from 2025 onwards for zero- and low-emission vehicles (ZLEVs). A ZLEV is defined as a passenger car or a commercial van with {{CO2}} emissions between 0 and 50 g/km. The regulation set ZLEV sales targets of 15% for 2025 and 35% for 2030, and manufacturers have some flexibility in how they achieve those targets. Carmakers that outperform the ZLEV sales targets will be rewarded with higher {{CO2}} emission targets, but the target relaxation is capped at a maximum 5% to safeguard the integrity of the regulation.<ref name=EUCO2fleet/><ref name=EUCO2Directive2019/>
=== Electrification === {{Update section|date=April 2021}}
Many EU member states have responded to this problem by exploring the possibility of including electric vehicle-related infrastructure into their existing road traffic system, with some even having begun implementation. The UK has begun its "plugged-in-places" scheme which sees funding go to several areas across the UK to create a network of charging points for electric vehicles.<ref>{{cite web |url=http://www.dft.gov.uk/topics/sustainable/olev/recharging-electric-vehicles/ |title=Recharging infrastructure |publisher=[[Department for Transport]] |access-date=22 December 2011 |archive-url=https://web.archive.org/web/20111222024540/http://www.dft.gov.uk/topics/sustainable/olev/recharging-electric-vehicles/ |archive-date=22 December 2011 |url-status=dead }}</ref>
