“We’ve now got carbon pricing on the radar screen in a way it hasn’t been before,” said the World Bank’s John Roome, “We’re moving from why to how.”

An April 24 New York Times story by Coral Davenport quoted Roome and others on the growing momentum of carbon pricing. “There is now an overwhelmingly obvious scientific consensus that the more carbon pollution we put into the air the more impact it has on warming the massive melting of the Arctic, the cycles of droughts and flooding, the die-offs of coral reefs,” the World Bank’s president, Jim Yong Kim, told Davenport. “And to our economists, who have been studying this for quite some time, there is an equally obvious consensus that putting a price on carbon pollution is by far the most powerful and efficient way to reduce emissions.”
