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一定程度的氢氟碳量，但其排放量仍不受限制。

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

氢氟碳有助于冰箱和空调的冷却，但科学家称它们加剧全球变暖。

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，将氢氟碳入其中，它们被逐步淘汰。

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

氢氟碳通常用于制冷，其对全球变暖的影响是二氧碳的10000倍。

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

该项规则的目的是未来15年内将氢氟碳（HFCs）的使用量减少85%。

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一项规则，严格限制使用叫作氢氟碳的气体冷却剂。

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

但氢氟碳据说是强烈的温室气体，估计占所有人类造成的大气变暖的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，危害最大的氢氟碳之一，被称为R-410A，用于非洲第二常见的空调。

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，而取代它们的替代品，氢氟碳（HFC）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》的近200个缔约国通过了一项修案，该修案将2047年之前削减全球80%-85%的氢氟碳排放。

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》的200个缔约方达成了《基加利修案》，该修案将逐渐减少制冷中常用的具有强温室效应的氢氟碳的产生和消耗。
