On December 12 in Paris, the UN’s Framework Convention on Climate Change concluded its 21st Conference of the Parties with a landmark agreement among the world’s nations to reduce emissions that increase global warming. The historic pact reflected unanimous agreement among 196 participating nations.

A number of SIPA faculty and students traveled to Paris to participate in a range of events surrounding the conference.

Earth Institute director Jeffrey Sachs, who is also Columbia University’s Quetelet Professor of Sustainable Development and a professor of health policy and management, is a prominent figure in the fight against global warming. He saluted the agreement and discussed the road ahead, observing that

“The diplomats have done their job: the Paris Agreement points the world in the right direction, and with sophistication and clarity. It does not, however, ensure implementation, which necessarily remains the domain of politicians, businessmen, scientists, engineers, and civil society.” (Reuters, December 12)

Scott Barrett, the Lenfest-Earth Institute Professor of Natural Resource Economics, argued in a written piece for PBS NewsHour that “More important than what happens in Paris is what happens after Paris.” (December 9)

David Sandalow, the inaugural fellow at SIPA’s Center on Global Energy Policy, has been an undersecretary and held other senior positions at the U.S. Department of Energy. He told CNN why the COP21 agreement is so important (“Landmark climate deal reached in Paris,” video, December 12).
