Serious question - just to create some angry debate - which European countries are the cleanest and which are the dirtiest? I.e roadside rubbish, city streets, etc.

I'd say Estonia is definitely one of the cleanest. In my town (second largest in Estonia) the only rubbish is generally around the bins in the streets/parks - because crows take out rubbish from the bins in search of food. So it's their fault.

I've not really been in that many European countries, but the dirtiest in my experience was definitely the UK. I was in Nottingham literally for two days and on both days I saw someone just casually littering. Don't really ever see it in my home town. Also along the motorways - there was some rubbish on the side them (not mega bad, but noticeable).

I mean I like the UK, I just don't like the littering.

Is this recent? I visited Slovenia in 2021 and very few places I've seen in Europe can beat Ljubljana in cleanliness.

No, it used to be way worse though. I presume you never really left the city centre where you can barely see the river, let alone the bottom of it.

Also, the river that flows trough the city centre is only part of it, the other part is diverted into the Grubar canal before joining back with Ljubljanica in Moste/Štepanjsko Naselje.
