They’ve just been discussing this on Sky News.
Whilst BEVs continue to see the biggest % growth (as you’d expect), they still only represent 800,000 of the 35,000,000 cars on our roads and only 17% of new vehicle sales are currently BEVs. You don’t have to be very good at maths to see that the 2030 date has to change significantly.
Some good news for the next government who has to announce this date change is that a poll today shows that only 1 in 4 people support the 2030 ban, so they will be pushing on an open door.
