  • The EU catches some car manufacturers in a new emissions scandal

    Two years after the famous 'Dieselgate', the European Union has found indications that some brands are trying to distort emissions in the most gross way, to avoid new upcoming regulation. In 2020, the European Union will adopt a new regulation that will set new limits on the pollutants emitted by the vehicles. To this end, the EU is collecting data  to establish these limits carefully. ...

  • How can industrial regulations be improved to avoid any potential emissions reporting scandal (Avoiding a VW type scandal)

    The VW automotive emissions testing scandal has signifi cant environmental implications due to the mismatch between expected and actual emissions of NOX . Many consider that the ultimate responsibility lies with VW on the issue, however it is important to consider the role of the regulator in supporting an industry backed testing regime which does not absolutely refl ect actual emissions. While ...

  • Real-world vehicle emissions as measured by in situ analysis of exhaust plumes

    Abstract We conducted a 60-day roadside measurement campaign on a busy street in Münster, Germany, during summer 2016. We used gas and particle concentration measurements with high temporal resolution (10 Hz) to quantify both the emission ratios of nitrogen oxides per carbon dioxide (NOx/CO2) for over 70,000 individual exhaust plumes as well as the emission ratios ...

  • Explaining vehicle emissions – why do laboratory and road measurements differ?

    The road transport sector is a major contributor to Europe’s emissions of greenhouse gases and air pollution. For certain pollutants, vehicles can emit substantially higher emissions on the road than official emissions tested in laboratories. A report released today by the European Environment Agency (EEA) provides a non-technical guide that describes the reasons for these often significant ...

  • Black carbon emissions of individual cars measured under real conditions

    Measurements of individual vehicle emissions are usually made in laboratory tests. In this study, researchers followed cars driving in real conditions to measure emissions of air pollutants, including black carbon and nitrogen oxides. The study shows that diesel cars contribute disproportionately to air pollution, and highlights the value of on-road measurements. Vehicle traffic is a major source ...

  • Technological solutions and behavioural change needed to decarbonise transport

    While the transport sector contributes significantly to society and the economy it also can cause substantial adverse impacts on the environment, global climate and human health. A new report by the European Environment Agency (EEA) analyses key environmental trends with a view to identifying what has improved and what has hampered the past performance of the transport sector. The transport ...

  • Monitoring CO2 emissions from new passenger cars and vans in 2014

    The European Environment Agency (EEA) supports the European Commission (EC) and European Union (EU) Member States in the monitoring of the carbon dioxide (CO2) performance of passenger cars, in accordance with Regulation (EC) No 443/2009, and of light commercial vehicles, in accordance with Regulation (EC) No 510/2011. The regulation for passenger cars sets a CO2 emission (1) target of 130 g ...

  • La Via on the car emissions scandal: `We want a real assessment of emission`

    Volkswagen, the German car manufacturer, has acknowledged that many millions of its cars sold worldwide have been specially equipped to trick emission tests, so as to appear less polluting.
