saying fuel type X in vehicle y produces 10% less of pollution W is a complete waste of time without considering the vehicle and supplychains

The supply chain is mostly outside the control of the UK and the EU.

They can only control what is sold/bought/used within the UK/EU.

We have to work with the economic tools we've got rather than wait for the entire world to agree to limit use of fossil fuels and pollution.]

I didn't say the UK......if you buy anything you have some degree of Control + a significant proportion of the supply chain is within the EU anyway...... just looking at what comes out of the exhaust pipe is nonsensical

Put a supercharged LS7 in it. You could then charge up all the Amperas in a 5 block radius.

Stick a big cummins in it and drive around redneckville, wait for someone to "roll coal" at you then gas them right back

It's interesting that not one person has mention VOC (volatile organinc compounds) yet, purported to be 10x more harmful to the environment than Co2 and NOx, though it's not a direct polluted to health

The ammount of unburnt hydrocarbons in the exhaust of a car is miniscule, it's not been an issue since cat's have been fitted.

Yes, given for the same density Petrol is. For comparison sake a reference Gasoline (used for emissions testing) typically has 46.20 MJ/Kg , whereas diesel has 45.68 MJ/kg. Density of Petrol is approx 0.745 kg/l, diesel is 0.834 kg/l

Those look like higher heating values? The lower heating value for petrol or diesel is 41.5 or 42.5 respetively, petrol is proportionaly worse than diesel as it's a higher ratio of hydrogen to carbon, therefore produces more water and less CO2 when burnt. The difference is important because a car's engine does not recover the waste heat from the exhaust or condense the water vapour in it.
