In July 2007, Vatican City announced a plan to become the first carbon-neutral state in the world, following the politics of the Pope to eliminate global warming. The goal would be reached through the donation of the Vatican Climate Forest in Hungary. The forest is to be sized to offset the year's carbon dioxide emissions. However, no trees have actually been planted . The company KlimaFa is no longer in existence and hasn't fulfilled its promises. In November 2008, the city state also installed and put into operation 2,400 solar panels on the roof of the Paul VI Centre audience hall.
