1. Less than historically still has a quite high baseline compared to after ULEZ - if it was more polluted, presumably the change seen here would be more dramatic.
2. Definitely kickstarted it, but we're looking at taking that impact and continuing it for some 5 years after covid ended now.
3. You can look at the ULEZ map and it really covers everything but the outer tube line suburbs [1].
5. The control group in Luton, presumably, has the same lifestyle changes - it's not that far away (about 30 miles), so it is as close as you can get to a one to one comparison, not accounting for the fact that Luton is likely to be more deprived than London (especially in the council estates, which have horrible reputations).
