NAIROBI,Kenya— The world has taken an important step on the road to drastically reduce the production and consumption of powerful greenhouse gasses known as HFCs and limit global warming, with the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer coming into force on Jan 1.
If fully supported by governments, the private sector, and citizens, the Kigali Amendment will avoid up to 0.4°C of global warming this century while continuing to protect the ozone layer. The amendment will substantively contribute to the goals of the Paris Agreement.
