What are we to make of the news that the German car manufacturer Volkswagen has been cheating on emissions tests for diesel cars in the USA? The first cries of ‘disgraceful’ from the media were followed by announcement that 11 million cars had the ‘cheat software’. There were apologies, resignations and drastic impacts on share prices. Subsequent stories expanded the focus of concern from Volkswagen to the Porsche partner companies (Audi and Skoda), who announced that 3.3 million of their cars were fitted with the same software as Volkswagen to cheat US emissions tests.
Should this be a surprise? Not really.
First, it is not surprising to find regulators revealed as useless: dogs with neither bark nor bite – especially in bureau-Europe. It has been known since 2011 that diesel cars driven on the road discharged far more nitrogen oxide and particulate than official tests reported, and had significantly worse fuel consumption. The testing regimes have been criticized as ‘not fit for purpose’, especially the bureaucratic mess that holds in the EU. The BBC reported the UK Committee on Climate Change saying that between 2002 and 2014 the gap between official and real-world CO2 emissions for new passenger cars increased from about 10% to 35%.
