Although Oristano is not among the top municipalities in terms of national GDP, it’s still a commendable reality regarding the urban ecosystem. This confirms that to improve the level of pollution in the city, often it’s enough simply to spend the few resources well, evolve, and plan future transformations.

8. Belluno


Present in the Top 10 for years, the quality of life in this city remains very good thanks to the improvement of waste collection and the good number of cycle paths.

7. Treviso


A classic city on a human scale, Treviso offers good quality of life due to its clean air, efficient transport, and good progress in reliance on renewable energy.

6. Pesaro


Pesaro is a new entry on this list. In recent years, the city has taken good measures to deal with the environmental emergency and the concept of pollution prevention. Today, it’s among the virtuous cities of Italy and its beaches offer waters among the cleanest in the country.

5. Parma


Parma deserves the leap forward above all due to the incredible increase in separate waste collection, which went from 8% to 72%!

4. Pordenone

Pordenone also stands out in a positive way thanks to its excellent urban state, with cycle paths and pedestrian areas.

3. Bolzano


Bolzano makes almost no mistakes. The amount of fine dust emission is excellent, almost 70% of the differentiated, only 30% of which come from private vehicles. An ideal town to live and grow!

2. Mantua


Mantua is a city where everyone would like to live. Excellent water network and sewage system, excellent air quality with low harmful emissions, and, most of all, the second city for the overall kilometers of cycle paths per inhabitant.

1. Trento


In the first place, we find Trento, the city that goes over 80% for separate collection. It is an almost unique case in Italy. If we add an excellent water network and an energy supply with over 50% coming from renewable energy to this, it’s clear why it wins this ranking!
