The European Environment Agency presents a study on the effect of transports on environmental indicators:
The last decade the person transports by cars have increased by 18% while it is also concluded that the high fuel price the summer 2008 increased the travels by the most cost efficient means, buses and coaches. A 10% increase of the fuel in average increased the demand for bus transports by 21%.
Somewhat misleading comparison is made between road and rail transports. While cars dominate in road transports key environmental indicators are not at their best. Interestingly, among the listed countries Turkey is the one that by far has the highest use of public transports. Turkey has also by far the highest portion of buses which brings a superior carbon footprint, to the lowest cost!
As I have written about previously in the blog, buses actually turn out as number one in environmental performance prior to other public transports.
