So where does the money come from, then? Extra income tax, perhaps? Are you prepared to pay an extra £500 tax in order to pay for a diesel car scrappage scheme? No. I thought not. At least the programme clearly laid the blame on misguided legislators who brought about an average reduction in CO2 by switching half of all car purchases throughout Europe to diesel. These same legislators actually penalise car manufacturers with fines for producing cars that emit an average of more than 130g/km CO2 in the NEDC prescribed tests for their entire production over 2015. Electric cars and hybrids are a tiny percentage of total production, so the only way this could be accomplished was by diesels. No one considered the true effect on NOx emissions in Europe. But they did in Japan, which is why, instead of concentrating on diesel, Toyota put its money into petrol hybrids 15 years ago. Toyota no longer even makes diesel engines for cars. It buys them from BMW.
