Sweden, Germany, and France all have experience with natural gas for transportation, showing that it is appropriate to promote using natural gas in busses and is possible to refuel a large number of vehicles at the same place. However, though there are many advantages of using natural gas for transport, and many car manufacturers already have developed natural gas-fuelled models, no one will buy vehicles until refuelling has become easy and accessible. Further, nobody will build filling stations until natural gas-fuelled vehicles begin to sell.

Sweden
Since the beginning of 1995, natural gas for transport purposes has remained at a constant level. But since 2001, growth has doubled until today. Early in 2006, there were 65 filling stations and approximately 5,000 vehicles, of which 500 were busses. Development could increase even further in the coming years, since the Swedish government has raised subsidies for establishing new filling stations.

Germany
By early 2006, Germany had 33,000 natural gas vehicles and approximately 700 filling stations. By 2011, the number of cars, busses and taxis is expected to reach 500,000.

France
In late 2005, the number of natural gas-powered vehicles in France reached 8,000, the great majority of those being public vehicles. Now natural gas busses are in approximately 20 French cities and it is expected that 30% of all new busses in the future will be fuelled by natural gas.
There are also 100 garbage trucks operating in nine cities and another 300 have been ordered.

Around 2005, Gaz de France decided to enter the consumer market. They are working together with the American company, Fuelmaker, and have now developed a new, compact, and rather inexpensive home filling station called Phill. It is expected to reach approximately 100,000 private natural gas cars by 2010.
