Personally I don't believe in the whole hyped up scenario concerning vehicle pollution when one major volcanic eruption puts more CO2 in the air than from all the cars ever made! Mind you I'm not a believer in the dogma of manmade climate change either.
Next you need to know that the increased use of diesel came about from 'Green' lobby groups who pushed for it as it produced less CO2 and they turned a blind eye to the fact that it was a dirtier fuel.
This is not the first time that 'Green' lobbyists have got things wrong as they were also largely responsible for the switch form leaded to unleaded fuel despite the fact unleaded fuel releases far more CO2 into the atmosphere than the old leaded!!
Anyway back to VW and the BBC and it pretty clear to me that the BBC is showing bias in its reporting.
On the six O'clock news on BBC 1 today they ended the item on VW by interviewing a commuter who drove from Cardiff to Bristol every day and owned a VW of course. He said that due to the current situation he would think twice before buying another VW.
This interview was clearly biased as there was NO attempt to achieve a balance as they only interviewed one person. Personally I have yet to speak to a person who rates car emissions as a factor in buying a new car.
As to the BBC holding the 'Greens' to account for getting the whole lead/unleaded and petrol/diesel arguments wrong don't hold your breath.
