During the opening weeks of the 71st United Nations General Assembly, the Paris Agreement on climate change has been a prominent issue and U.N. members have been strongly encouraged to sign on to the accord.

As of September 21, 2016:

…60 countries representing 48 percent of global planet-warming emissions have now legally bound themselves to the Paris accord. The deal goes into legal force when at least 55 countries representing 55 percent of global emissions sign on. At Wednesday’s ceremony, leaders of countries representing at least an additional 12 percent of global emissions pledged to submit their legal documents by the end of this year. If they follow through, the pact will take effect.
