The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020. It also looks at which models have been found to have the biggest gap between claimed CO2 emissions and real-world performance.
Unless you have buried your head in the sand over the last couple of days, you would have been hard pressed to miss the VW cheating scandal that has erupted in the United States. A tsunami of media stories have taken over the front pages of the FT, NYT, The Guardian, Le Figaro, Il Sole 24 Ore, to name a few.
The prospect of Volkswagen being fined $18 billion for manipulating air pollution tests in the US caused its shares to fall 22% and is sending shock waves through the automotive industry. VW has been ordered to recall nearly 500,000 cars, meaning a massive bill to correct the vehicles and potential class action claims for compensation. After initially refusing to comment, CEO Winterkorn issued a statement saying he was “very sorry”. The evidence suggests he will not be the last head of a carmaker offering apologies in the next few months as other manufacturers will be found making use of “defeat devices” for tricking laboratory tests.
Every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by sustainable transport group Transport & Environment (T&E). All new diesel cars should have met the Euro 6 auto emissions standard from 1 September – but just one in 10 tested complied with the legal limit. (See infographic)
A consortium of car manufacturers, suppliers and repairers has, in an attempt to hide the fact that a typical diesel car emits 10 times more nitrogen oxides than an equivalent gasoline car, launched a new website. Its content ignores the inconvenient truth that new diesels can’t reach the limits agreed back in 2007 without fitting new technology. This briefing provides six facts about diesel cars that the industry would rather the public didn’t know.
Harmful levels of air pollution are endemic in European cities, especially close to roads, causing 400,000 premature deaths annually and costing the EU a whopping €1 trillion a year. This paper focuses on the role played by diesel cars in the air pollution crisis and identifies obsolete tests and optimisation strategies by car manufacturers as the reasons they have failed to deliver real-world improvements. It explores the Commission’s proposed new real-world driving (RDE) test, which is to be implemented for new Euro 6 standard vehicles, and outlines a timetable to address important issues relating to air pollution from cars.
The current system for testing car CO2 emissions and fuel economy, the NEDC, is obsolete. Thankfully, a new test, the WLTP, is scheduled to replace the NEDC in 2017. To do this, the average CO2 emissions target for cars (95 g/km for 2020/1) needs to be revised in a way that maintains “equivalent stringency” between the tests.
In these documents, T&E responds to the public consultations on the EU Effort Sharing Decision (ESD) and Land use, Land Use Change and Forestry (LULUCF). As transport is currently the largest sector within the ESD, it is vital to have a strong ESD with limited flexibilities to avoid watering down the EU climate targets and to achieve reductions in the transport sector. The way LULUCF is dealt with is also fundamental to avoiding a decrease in the level of ambition in sectors such as transport. For these reasons, T&E provided input to both consultations in close coordination with other environmental NGOs.
This briefing paper explains why setting 2025 CO2 standards for cars and vans offers benefits for drivers in lower fuel costs, job creation, energy security and tackling climate change. It is available in full and summarised versions. The paper highlights how the EU is falling behind in developing advanced efficient powertrains compared to competitors in Asia; and that due to testing flexibilities by 2021 the average vehicle is still likely to emit 150g CO2/km – meaning less than half of the anticipated savings through the regulation will be delivered.
The EU set legally-binding targets for new cars to emit on average 130 grams of CO₂ per kilometre (g/km) by 2015 and 95g/km by 2021. This report, the 10th annual edition in the series by T&E, analyses the official data from the European Environment Agency on progress towards these targets made by carmakers in 2014.
