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 City
Vatican City's climate is the same as Rome's: a temperate, Mediterranean climate "Csa" with mild, rainy winters from October to mid-May and hot, dry summers from May to September. Some minor local features, principally mists and dews, are caused by the anomalous bulk of St Peter's Basilica, the elevation, the fountains and the size of the large paved square.
In July 2007, the Vatican accepted a proposal by two firms based respectively in San Francisco and Budapest, whereby it would become the first carbon neutral state by offsetting its carbon dioxide emissions with the creation of a Vatican Climate Forest in Hungary, as a purely symbolic gesture to encourage Catholics to do more to safeguard the planet. Nothing came of the project.
