Or so reports Catholic News Service today.
In and of itself, the item is not that big a deal: The Vatican will be installing solar panels atop the Pius VI Hall, where the pope holds his general audiences. It does seem, however, to be indicative of greater emphasis being placed on environmental stewardship by the leadership of the Catholic Church (among other eccesial bodies, as has been much remarked on this blog). There was no official comment from the Vatican, but the news writer linked the story to the wider context:
Even though Vatican City State is not a signatory of the Kyoto Protocol, a binding international environmental pact to cut greenhouse gases, its inaugural solar project marks a major move in trying to reduce its own so-called carbon footprint, that is, the amount of carbon dioxide released through burning fossil fuels.
