In recent years, the Catholic Church has been more active on environmental issues, urging people to be better stewards of the Earth while holding itself up as a model. In 2007, Pope Benedict XVI, dubbed “the green pope” for his environmental initiatives, announced his intention to make the Vatican Europe’s first carbon-neutral state, starting with solar panels on the Vatican’s auditorium that produce 300,000 kilowatt-hours a year, coupled with extensive efforts to conserve energy.
