So, which cities in Europe are the most sustainable and which are doing their best to protect the planet? To find out, we’ve launched a study analyzing Europe’s most visited cities on a series of sustainable factors.
Europe’s most sustainable destinations
1. Berlin, Germany - 6.98 sustainable city score
Topping our list is Berlin, Germany. The city is well known for being a progressive destination, and residents are continuously embracing new green innovations, so it makes sense that sustainability is very important here.

Visitors to Zürich benefit from its efficient public transport system. There are bus or tram stops every 300m of the city.
