The First Carbon Neutral State October 14, 2010 : 5:31 PM

That is what the Vatican would like to become:

“The Holy See has embarked on a new mission: the fight against climate change. In 2007, Pope Benedict XVI announced that Vatican City would strive to become the first carbon-neutral state. Although the Vatican’s plan to purchase carbon offset credits fell through, the sovereign city-state has harnessed the power of the sun with solar panels and a solar generator, and has also made progress with energy conservation efforts. Pope Benedict has added a religious element to the climate change debate by framing the issue as a moral imperative.”
