It appears around a million Europeans bought petrol cars rather than diesels in 2018. HRUX’s own sums suggest that, over their lifetimes, those cars will emit nearly 3 million tonnes or more CO2 than the diesels Europeans were buying.

Is that a lot? Does that matter? If the trend continues – that number will just keep growing.

Independent research suggest the latest diesel cars have very low emissions of NOx. Less than new petrols. Many many times less then the older diesel cars that many people have chosen not to replace.

Yes the future IS electric, but most commentators agree we’re not there yet – not least because of the supply issues. By attacking diesel have we missed the opportunity to cut emissions across the board in the short to medium term?
