HFCs help cool refrigerators and air conditioners, but scientists say they help fuel global warming.

氢氟碳化物有助于冰箱和空调，但科学家称它们在加剧全球变暖。

Emissions of HFCs are unrestricted, though CDM investments are used to reduce them in some cases.

清洁发展机制曾投资减少定程度氢氟碳化物量，但其排放量仍不受限制。

These chemicals, which are commonly used in refrigeration, can have 10,000 times more global warming potential than carbon dioxide.

氢氟碳化物通常用于制，其对全球变暖影响是二氧化碳10000。

The rule aims to reduce the use of hydrofluorocarbons, called HFCs, by 85 percent over the next 15 years.

该则目是在未来15年内将氢氟碳化物（HFCs）使用量减少85%。

So in 2016, the Montreal Protocol was amended to include HFCs and now they are being phased out too.

因此，2016年，《蒙特利尔议定书》被修订，将氢氟碳化物纳入其中，现在它们也正在被逐步淘汰。

The U.S. Environmental Protection Agency has finalized a rule to sharply limit the use of coolant gases known as HFCs.

美国环境保护署最终确定了则，严格限制使用叫作氢氟碳化物气体剂。

But HFCs are said to be strong greenhouse gases and account for an estimated 2 percent of all human-caused warming in the atmosphere.

但氢氟碳化物据说是强烈温室气体，估计占所有人类造成大气变暖2%。

One of the most harmful HFCs, called R-410 A, is used in the second most common kind of air conditioners in Africa, the AP reported.

据美联社报道，危害最大氢氟碳化物之，被称为R-410A，用于非洲第二常见空调。

While the ban was a win for the climate, as CFCs are potent greenhouse gases, the alternatives that replaced them — hydrofluorocarbons, or HFCs — are too.

这个禁令对气候十分有利；CFC 是强效温室气体，而取代它们替代品，氢氟碳化物（HFC）也是。

And on October 15th, nearly 200 Parties of the Montreal Protocol agreed to an amendment that will reduce global HFC levels by 80 to 85 percent by the year 2047.

10月15日，《蒙特利尔议定书》近200个缔约国通过了修正案，该修正案将在2047年之前削减全球80%-85%氢氟碳化物排放。

And finally, 200 Parties of the Montreal Protocol agreed to the Kigali Amendment that will gradually reduce the production and consumption of hydrofluorocarbons, powerful greenhouse gases that are commonly used in refrigeration.

最终，《蒙特利尔议定书》200个缔约方达成了《基加利修正案》，该修正案将逐渐减少制中常用具有强温室效应氢氟碳化物产生和消耗。

The most popular options—also used by fridges and heat pumps—are hydrofluorocarbons (HFCs), potent greenhouse gases which are between hundreds and thousands of times more effective at warming the atmosphere than CO2.

最受欢迎选择——冰箱和热泵也使用——是氢氟碳化物 (HFC)，这是种强效温室气体， 其对大气变暖效果比二氧化碳高出数百至数千。
