The European Commission has acknowledged that carmakers used tools to optimise their emissions test in the laboratory over the past few years, although officials argued that these techniques did not imply that the companies were using fraudulent software. However, the US Environmental Protection Agency (EPA) revealed that Volkswagen went beyond this optimisation, by installing “defeat devices” in their vehicles to cheat the laboratory tests.
Diesel vehicles produce highly dangerous nitrogen-oxide emissions, on of the most carcinogenic substances to humans.
The Organisation for Economic Cooperation and Development (OECD) pointed out last year that taxes for diesel should be higher than for petrol, bearing in mind the higher level of emissions of both carbon dioxide and harmful air pollutants than gasoline. In addition to environmental considerations, this hike would be justified in light of other social costs, the Paris-based organisation said, as diesel vehicles travel further on a litre of fuel.
