You’re right, there’s no mention of resident grace period any more, so 2021 is most likely.
From my basic survey of cars on the road, I really don’t see it making much difference. The majority of private cars are already low emissions because they’re relatively new, taxing older cars will barely make a dent. On one hand they’re trying to say it’s such a big problem that they need to reduce it to reduce pollution but then in the same breath they’re trying to say not that many residents will be affected. Which is it?
Where I can see it will make a difference is with white vans particularly with the extension of LEZ to Euro 6. Only vans from 2015 onwards will be compliant and this could have quite an affect on smaller business's.
