EVs are still exempt, and I've had £9.5K worth of government EV 'grants' go towards the EV purchases and x2 home chargers installed for free. Hope the scheme is still going in 2018/19 so that we'll get another £4,5K off the list price on the Jag iPace.
As for emissions I cannot be bothered to point out the obvious facts over preconceptions anymore, this piston-heads thread does it all for me, and i don't even think I've made a post on it!!

Aren't they only exempt after the 5th year if they are over £40k? Of course cheaper EV's are exempt from VED, but I don't necessarily agree with it.
As for your link, I don't have time to read it now, but if it's about the emissions in creating electricity for EV's, and it's showing it's much less than petrol/diesel, I agree, but it's not Zero however, so therefore should have to pay.
