据ICIS网站3月2日消息 国际能源署（IEA）周二表示，由于第二季度的停工导致的平静，2020年全球二氧化碳（CO2）排放量同比下降，但到12月，这一数字已经比2019年同期高出2%。
各国缺乏清洁能源政策的情况由于经济从第一波新冠疫情中复苏而变得更为严重。温室气体排放（GHGs）主要受传统化石燃料推动，二氧化碳就是其中之一。
IEA表示，2020年全球与能源相关的二氧化碳排放量同比下降5.8%，这是自第二次世界大战以来最大的年度百分比下降。
IEA表示：“从绝对值来看，近20亿吨二氧化碳排放量的下降在人类历史上是没有先例的，从广义上讲，这相当于将欧盟的所有排放量从全球总量中剔除。”
但总部设在巴黎的该机构表示，到12月观察到的反弹，以及许多国家的排放量已经达到疫情前的水平，是一个令人担忧的迹象。
IEA执行主任法蒂赫·比罗尔说：“去年年底全球碳排放量的反弹是一个严峻的警告，表明在加速全球清洁能源转型方面做得还不够。”
“如果各国政府不迅速采取正确的能源政策，这可能会危及世界的历史机遇，使2019年成为全球排放量的最终峰值。”
“如果目前对今年全球经济反弹的预期得到证实，并且在全球最大经济体没有重大政策变化的情况下，2021年全球排放量可能会增加。”
IEA的警告将使人们对2019年是排放高峰年的希望面临风险；排放量的下降付出了巨大的社会和经济代价，尽管有人谈论疫情后的绿色复苏，但化石燃料的使用可能在2020年代仍占主导地位，排放量可能尚未达到峰值。

Global CO2 emissions fall in 2020 but recovery causing rapid rebound - IEA
Global carbon dioxide (CO2) emissions were lower in 2020 year on year due to the lockdowns-induced lull in the second quarter, but by December they were already 2% higher than in the same month of 2019, the International Energy Agency (IEA) said on Tuesday.
Countries’ lack of clean energy policies was compounded by the economic recovery from the first wave of the pandemic, which has been powered by the traditional fossil fuels that emit greenhouse gases (GHGs) causing global warming; CO2 is one of them.
The IEA said global energy-related CO2 emissions fell by 5.8% in 2020, year on year, the largest annual percentage decline since the Second World War.
“In absolute terms, the decline in emissions of almost 2,000m tonnes of CO2 is without precedent in human history – broadly speaking, this is the equivalent of removing all of the EU’s emissions from the global total,” said the IEA.
But the rebound observed by December, and the fact that many countries’ emissions have already reached pre-pandemic levels, was a worrying sign, said the Paris-based Agency.
"The rebound in global carbon emissions toward the end of last year is a stark warning that not enough is being done to accelerate clean energy transitions worldwide,” said Fatih Birol, the IEA’s executive director.
“If governments don’t move quickly with the right energy policies, this could put at risk the world’s historic opportunity to make 2019 the definitive peak in global emissions.
“If current expectations for a global economic rebound this year are confirmed – and in the absence of major policy changes in the world’s largest economies – global emissions are likely to increase in 2021."
The IEA's warning will put at risk hopes that 2019 was the peak year for emissions; the drop in emissions came at a huge social and economic cost and, despite talk of a green recovery post-pandemic, fossil fuels use is likely to be still dominant in the 2020s, with emissions possibly yet to peak.
