The deal, agreed by US Secretary of State John Kerry, will see developing countries, including those in Europe, reducing their use of the gas by 10% in 2019.
More than 100 developing countries, including China, will freeze their use fo the gas and start taking reducing it in 2024.
A small group of countries including India and some Gulf states secured a later deadline of 2029, saying their economies need more time to grow.
The talks have been called the first test of global will since the historic Paris Agreement to cut carbon emissions was reached last year.
HFCs are described as the world’s fastest-growing climate pollutant and are used in air conditioners and refrigerators.
