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程度的氢氟碳化物量，但其排放量仍不受限制。

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》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。

These include air conditioners that can use heat pumps, and water, instead of chemicals like HFCs as a refrigerant.

其中包括可以使用热泵和水，而不是像氢氟碳化合物这样的化学物质作为制冷剂。

International agreements aim to reduce HFC use by 85% by 2050, but their implementation is still piecemeal and patchy.

国际协的目标是到2050年将HFC的使用量减少85%，但其实施仍然零散且不均衡。

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的温室体，估计占所有人类造成的大的2%。

To address this, in 2016, the Kigali Amendment was added to the Montreal Protocol, calling for an 85% cut in global HFCs by 2047.

为了解决这个问题，2016 年，基加利修正案被加入了《蒙特利尔》，呼吁在 2047 年实现全球 HFC 85% 的削减。

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，危害最大的氢氟碳化物之一，被称为R-410A，用于非洲第二常见的空调。

With innovative new methods being trialled from technology to make air conditioners more efficient to completely eradicating the need for HFCs at all.

通过从技术上试用创新的新方法，使空调更高效，以完全消除对 HFC 的需求。

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.

这个禁令对候十分有利；CFC 是强效温室体，而取代它们的替代品，氢氟碳化物（HFC）也是。

Sellers and installers of cooling equipment in Nigeria told the news agency that although HFC systems are less damaging to the environment, they are more costly to operate.

尼日利亚的制冷设备销售商和安装商告诉通讯社，尽管HFC系统对环境的破坏较小，但它们的运营成本更高。

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》的近200个缔约国通过了一项修正案，该修正案将在2047年之前削减全球80%-85%的氢氟碳化物排放。
