12月12日,《联合国气候变化框架公约》近200个缔约方一致同意通过《巴黎协议》。这是第一份让所有国家都承诺减少碳排放的协议,比1997年的《京都议定书》覆盖面更广。笔者了解到,这份31页的协议主要内容是尽快让温室气体排放达到峰值,本世纪下半叶实现温室气体净零排放;将全球温度较工业化前水平上升的幅度控制在“远低于”2℃以下,并尽量限制在1.5℃以下等。
On December 12, nearly 200 Parties to the UN Framework Convention on Climate Change agreed to adopt the Paris Agreement. This is the first agreement that all countries have promised to reduce their carbon emissions, covering the 1997 Kyoto Protocol. The author understands that the main content of this 31-page agreement is to achieve the peak of greenhouse gas emissions as soon as possible and to achieve zero net greenhouse gas emissions in the second half of this century; to control the increase in global temperatures above pre-industrial levels to well below “ ”2 ℃ below, and try to limit below 1.5 ℃ and so on.
