Facts & Figures

Not only does Euro 6 set the strictest NOx and PM emissions limits yet, it also requires – for the first time – on-road testing to prove new cars can deliver low emissions on the road.

    • Average new car CO2 emissions rose in 2018, up 2.9% to 124.5g/km.
    • A 2018 car has on average CO2 emissions 31.2% lower than in 2000 and 20% lower than the average car in use.
    • Industry is delivering even lower CO2 emitting products, and new models introduced in 2018 had CO2 emissions on average 8.3% lower than the model they replaced.
    • The rise in 2018 reflected on-going market trends, notably consumer shift towards larger vehicles and the 29.6% drop in diesel registrations.
    • Diesels typically emit 15%-20% lower CO2 emitting than petrol cars (with like-for-like performance).
    • Zero emission battery electric vehicles took a 0.7% share of the market, plug-in hybrids a 1.9% share and conventional hybrid electric vehicles a 3.4% share in 2018. 
    • Alternatively fuelled vehicles (AFV) registrations continued to rise in 2018, up 20.9% to give them a 6.0% share of the market. AFVs emitted on average 45% lower CO2 than the market average.
    • The average new light commercial vehicle (LCV, or van) emitted 166.9g/km in 2018, 0.9% below the 2017 level – in a significant pick up in the rate of improvement – and 15.9% down on 2011.
    • The UK has some of the most challenging economy-wide CO2 reductions targets in the world, including plans to decarbonise the vehicle fleet by 2050. Delivering such market transformation demands all stakeholders working together to achieve environmental targets in the most cost-effective way possible, and enabling the UK manufacturing industry to be best placed to deliver these lower emitting vehicles.
    • The UK government has played a significant role in supporting industry’s CO2 reduction strategies. Key initiatives include the joint funded Advanced Propulsion Centre and the Go Ultra Low campaign.

  • PEMs testing

    • It would take 50 new cars to produce the same amount of pollutant emissions as one vehicle built in 1970 (DEFRA)
    • UK NOx emissions from passenger cars have fallen 81% since 1990 – the biggest reduction of any sector. (DEFRA AQPI)
    • The latest diesel cars are the cleanest in history, with high tech filters capturing 99% of all soot particles and exhaust after-treatments, reducing emissions limits of nitrogen oxides (NOx) by 84% since 2000. (Euro standards)
    • One in every three cars on UK roads is fuelled by diesel, and their drivers rely on them to travel 118 billion miles every year. On average, diesel cars cover 60% more miles than their petrol counterparts.
    • Euro 6 technology is proven to work in the real world. Tests of new Euro 6 buses using the London 159 Bus Route show a 95% drop in NOx emissions over older Euro-5 vehicles. (Transport for London)
    • On-road testing for cars was introduced for new models in 2017, with Europe the first in the world to implement it.
