Ice vehicles run on petrol ,LPG and diesel (and there is a plentiful supply at this moment in time, with supply chains and infrastructure already in place) ,and modern Vehicles are very efficient at converting the chemical energy into movement ,with relatively LOW emissions.
Scrapping perfectly good ICE vehicles to replace them with flawed EVs is very polluting, Globally !
People who think they are "saving the planet, being green " by currently buying and using EVs , are only 50% correct , they are "green" in the sense they are unwise to the reality

With everything going on in the world at this moment in time ,the UK are not anywhere near "ready" to entertain swapping from proven technology of ICE vehicles with infrastructure already in place ,to 1960s milk float technology

The UK can't meet electricity generation requirements for homes and industry(not that there's much of that left in the UK) without importing Biomass and coal (from thousands of miles away ) also importing gas and electricity ,solar panels and tech from China etc ,none of which is very "green" ,let alone provide electricity for EVs .
So to entertain scrapping ICE transport to use EVs is madness at this current time

The national grid is not ready to provide power for EVs (and when it is lots of energy will be wasted due to distribution losses),
Charging infrastructure is not ready, well behind unrealistic targets set by greedy politicians (lining their own pockets) ,
The road network is not ready (because EVs are heavier and rip up the roads which are already in a very poor state of repair) ,
The UK (as a supposedly civilised society) should NOT be ignoring the human rights violations, child labour etc going on in the world ,to provide raw materials (all of which need very polluting processing and transport) and imported parts and tech for EVs ,
Stupidly trying (because it's already failed on so many levels) to swap to EVs at this time, is costing everyday working folk a fortune in increased energy costs . clean air zone fees, increased cost of food, supplies etc , many of which can't afford it ,some rely on Government handouts, food banks etc ,so politicians ,who will be retired on a big fat pension and all the money they have extorted from working folk by the time any positive environmental impact in the UK is felt .
I say UK , because the likes of China will just ramp up pollution to supply " a green pipedream" to the stupid countries like the UK
I've barely scratched the surface of the argument to delay EV roll out 
As for "Links and statistics" I've already researched and read many arguments for and against the madness of premature EV roll out in the UK

as have many OOF members ,there's quite a few intelligent members on OOF

NOT all

so I won't bother ,use the internet
