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.[1] The Vatican's acceptance of the offer, at a ceremony on July 5, 2007, was reported as being "purely symbolic",[1] and a way to encourage Catholics to do more to safeguard the planet.[2] No trees have been planted under the project and the carbon offsets have not materialized.[3][4]
In May 2007, the Vatican announced that the roof of the Paul VI Audience Hall would be covered with photovoltaic panels.[5] The installation was officially placed into service on November 26, 2008.[6]
