Europe’s most polluted city Milan has joined Stockholm and London in making petrol-driven cars pay to enter the city center. CNG cars, on the other hand, do not need to pay.

Strict new European Union health targets are putting natural gas in the driving seat. Engineers planning the next generation of cars say they have picked a winner.

According to Professor Ennio Macchi from Milan’s Polytechnic Energy Department, “natural gas is the easiest and less costly way to reach this target.”

Europe’s top natural gas automaker is Fiat. Last year, it sold 120,000 such cars in Italy alone. Many models now have gas versions. The drawback is that there are relatively few CNG filling stations.

Fiat believes Russian energy giant Gazprom can fix that.

“Gazprom is sponsoring a project named ‘Blue Corridor’ for the development of a network of filling stations around Europe. This project is endorsed by the European Commission. Recently, on April 28, there was the adoption from the European Commission of the so-called Communication on Clean and Efficient Vehicles, in which CNG is part of future mobility,” Fiat’s Senior Vice-President Daniele Chiari says.

Ecologists warn that major oil companies such as Shell are lobbying the EU to scrap climate change goals, but a growing number of drivers have already made up their minds.
