Just over a quarter-century ago, the world united to reverse the rapid depletion of the atmospheric ozone layer, which protects Earth from harmful radiation from space. Today, the ozone layer is well on track to recovery within the next few decades.
二十五年前，国际社会团结起来，以扭转保护地球不受空间有害辐射影响的大气臭氧层快速损耗的趋势。如今，臭氧层已经能够在今后数十年中得到恢复。
The Montreal Protocol on Substances that Deplete the Ozone Layer is widely recognized as one of the most successful environmental treaties in history. It establishes legally binding controls on the national production and consumption of ozone-depleting substances, and enjoys universal ratification by 197 parties.
《关于消耗臭氧层物质的蒙特利尔议定书》是历史上普遍公认的最为成功的环境条约之一。它对各国消耗臭氧物质的生产和消费实行具有法律约束力的管制，得到了197个缔约方的普遍批准。
Recent scientific findings reveal the importance of the Montreal Protocol. Without the Protocol and associated agreements, atmospheric levels of ozone-depleting substances could have increased ten-fold by 2050. Concerted action has prevented millions of cases of skin cancer.
最近的科学调查结果揭示了《蒙特利尔议定书》的重要性。如果没有《议定书》及其相关协议，大气中消耗臭氧物质到2050年时会增加10倍。共同采取的行动防止了数百万例皮肤癌。
The Protocol has also significantly contributed to the fight against climate change, as many ozone-depleting substances are powerful greenhouse gases. Climate change is affecting communities, economies and ecosystems across the globe. It is essential that we act to mitigate the threat with the same unity of purpose as we have in facing the dangers of ozone depletion.
《议定书》还为阻止气候变化做出了重大贡献，因为许多消耗臭氧物质都是强大的温室气体。气候变化正在对世界各地的社区、经济体和生态系统产生影响。我们必须采取行动，像我们在应对臭氧损耗威胁时那样，团结起来消除这一威胁。
Let us take inspiration from our efforts to preserve the ozone layer. The Montreal Protocol has shown that decisive action by the international community, including the private sector, can achieve transformative results for the common good. Let us learn from this example and apply its lesson to the urgent task of addressing the climate challenge.
让我们从我们为保护臭氧层做出的努力中得到启发。《蒙特利尔议定书》表明，国际社会，包括私营部门，果断采取行动，就可以取得维护共同利益的巨大成果。让我们从这个范例中汲取经验，并在应对气候挑战的紧迫工作中加以利用。
