The International Energy Agency (AIE) warned on Tuesday (2nd) that global carbon emissions have begun to rebound sharply after a historic decline last year due to the COVID-19 epidemic, and carbon emissions are expected to rise again this year. The International Energy Agency said, "After reaching a low in April last year, global carbon emissions have rebounded sharply, rising above 2019 levels in December." Global carbon emissions in December last year were 2% higher than the same period a year earlier, that is, 60 million tons of carbon dioxide. According to the latest data from this special report by the Energy Agency, global carbon emissions fell by 5.8% last year, which is a reduction of approximately 2 billion tons of CO2. This is the largest decline in human history. The decline previously cited by the Energy Agency was larger, around 7%. Furthermore, there are huge differences between countries. The report pointed out that China was the only country whose carbon emissions increased last year compared with 2019, with an increase of 0.8%, or 75 million tons of CO2, making it the world's largest emitter of greenhouse gases; while the United States' carbon emissions decreased by 10% in 2020 .
