Poland really has a lot of work to do compared with everywhere else nearby and the north of Italy looks really bad too.
I did not expect such "decent" results over here in the UK, especially in the centre of London. Unfortunately, there isn't information for my area just outside of London but I presume it would be as good or slightly better.
Ash especially in the centre of London.
I guess there is not much industry in London these days, just offices, homes and commerce?
Yeah. The majority of London, especially in the centre is just offices, homes, and shops. I thought it would be worse due to our heavy usage of cars but I guess that has decreased recently with the congestion charge in Central London.
