A global deal to limit the use of hydrofluorocarbons (HFCs) in the battle to combat climate change is a “monumental step forward”, John Kerry, the US secretary of state, has said.
The agreement, announced on Saturday morning after all-night negotiations in Kigali, Rwanda, caps and reduces the use of HFCs – a key contributor to greenhouse gases – in a gradual process beginning in 2019, with action by developed countries including the US, the world’s second worst polluter.
Worldwide use of HFCs has soared in the past decade as rapidly growing countries like China and India have widely adopted air conditioning in homes, offices and cars. But HFC gases are thousands of times more destructive to the climate than carbon dioxide, and scientists say their growing use threatens to undermine the Paris accord by 195 countries, an agreement last year to reduce climate emissions.
President Barack Obama praised the deal on Saturday morning, calling the agreement “an ambitious and far reaching solution” to a “rapidly growing threat to the health of our planet”.
