Hydrofluorocarbons also known as HFCs are the world’s fastest-growing climate pollutant and are used in air conditioners and refrigerators. Recently, a worldwide deal has been reached to limit the use of greenhouse
gases in a major effort to fight
climate change.
HFCs were introduced in the 1980s as a substitute for ozone-depleting
gases. But their danger has grown as air conditioner and refrigerator
sales have soared in emerging economies such as China and India. HFCs are also found in inhalers and insulating foams.
