"The Kigali Amendment to the Montreal Protocol would cut HFCs, potent greenhouse gases widely used in air conditioners and refrigerators. "
"The Trump administration joined countries around the world last week in endorsing a powerful climate agreement that could cut greenhouse gas emissions enough to prevent as much 0.5 degrees Celsius of warming.
It's called the Kigali Amendment, and it targets a potent group of greenhouse gases called hydrofluorocarbons, or HFCs, that have been widely used as coolants in air conditioners and refrigerators. This month, Sweden became the 20th country to ratify the amendment, crossing the threshold for it to enter into force in January 2019.
Even as the Trump administration has spurned the Paris climate accord, the United States is continuing its involvement in this other main international agreement on global warming pollution."
