KIGALI, Rwanda — Negotiators from more than 170 countries on Saturday reached a legally binding accord to counter climate change by cutting the worldwide use of a powerful planet-warming chemical used in air-conditioners and refrigerators.
The talks in Kigali, the capital of Rwanda, did not draw the same spotlight as the climate change accord forged in Paris last year. But the outcome could have an equal or even greater impact on efforts to slow the heating of the planet.
President Obama called the deal “an ambitious and far-reaching solution to this looming crisis.”
