"A group of Republicans senators is pushing President Trump to let them approve a treaty amendment meant to cut emissions of certain greenhouse gases.

The Obama administration helped negotiate the Kigali amendment in 2016, meant to phase out hydrofluorocarbons (HFCs) around the world. HFCs are used mainly in refrigeration and air conditioning and are thousands of times more potent than carbon dioxide in warming the atmosphere.

But Trump still hasn’t decided whether he supports it, in which case he would have to send it to the Senate for ratification."
