The diesel emissions scandal, which started with Volkswagen, is now sweeping across the entire motor industry, with Renault, and Fiat Chrysler among the latest big name brands to be accused of cheating emissions tests.
What this proves, once and for all, is that diesel engines are too dirty – and dangerous to human health – to be allowed to continue to enjoy low tax rates (11 cent per litre less than petrol) and cheaper prices at the pumps, according to An Taisce, which also favours banning diesel vehicles from built-up areas, including Dublin city centre.
