"London is green" makes sense.

[optimistic pessimist]

Dear all,

If you say, "London is greener than Tokyo", it makes sense to me.
However, is it fine just to say "London is green" or "London is a green city" to mean theres's a lot of trees or plants in London?

Thank you!

It is, but it could also be taken as meaning that London is an ecologically green city, which would be a bit of an exaggeration.
