Vatican City
Vatican City has a reasonably well-developed transport network considering its size (consisting mostly of a piazza and walkways). A state that is long and wide, it has a small transportation system with no airports or highways. The only aviation facility in Vatican City is the Vatican City Heliport. Vatican City is one of the few independent countries without an airport, and is served by the airports that serve the city of Rome, Leonardo da Vinci-Fiumicino Airport, and to a lesser extent Ciampino Airport.
Vatican Climate Forest
The Vatican Climate Forest, to be located in the Bükk National Park, Hungary, was donated to the Vatican City by a carbon offsetting company. The forest is to be sized to offset the carbon emissions generated by the Vatican during 2007. The Vatican's acceptance of the offer, at a ceremony on July 5, 2007, was reported as being "purely symbolic", and a way to encourage Catholics to do more to safeguard the planet. No trees have been planted under the project and the carbon offsets have not materialised.
