Diesel
"It estimated that 55 per cent of this was attributable to consumers buying less efficient models and 45 per cent to consumers switching from diesel to petrol cars."
So diesel has less emissions than petrol after all ?
That was the case when I bought my diesel car. Since then, particulate output has apparently risen (despite it having proprietary particulate reduction system), diesel fuel prices have risen (for no other reason than market size, I think) and petrol fuel economy has improved. Diesels are no longer seen as desirable. Unsurprisingly, demand has moved back towards petrol with no huge interest in electric due to range and charge concerns (valid or not) and cost.
So why the push back to petrol, if it results in higher emission levels ?
