Vatican highlights sustainability at St. Peter's basilica (Vatican Press Office)

At a June 16 press conference, Vatican officials called attention to efforts that will make St. Peter’s basilica more environmentally friendly, including the use of solar power, LED lighting, and more efficient air-circulation systems.

Cardinal Mauro Gambetti, the archpriest of the Vatican basilica, stressed the importance of a response to climate change, saying tahat “because the more the environmental crisis is normalized and passively accepted, the more dangerous and urgent it is to deal with, I believe it is time to show the goodness and foresight of official climate plans.”
