December 11th – CNBC News reported on the 10th that the University of East Anglia in the United Kingdom, the University of Exeter in the United Kingdom and the Global Carbon Project jointly released a report that global greenhouse gas emissions will be reduced by about 2.4 billion tons in 2020, a decrease of 7% from 2019, the largest on record.
Global daily carbon emissions fell 17 percent during the pandemic lockdown in April but have since risen again, near 2019 levels, according to the report. Researchers say global carbon emissions may rebound in 2021, and urge governments to prioritize the transition to clean energy and formulate more policies to combat climate change in their economic recovery plans.
According to the report, the U.S. saw the largest drop in carbon emissions in 2020, at 12%, followed by the European Union with a 11% decline. The above two areas have accelerated the use of coal and oil due to restrictions during the pandemic. Among developing countries, India’s carbon emissions fell by 9%, and China fell by 1.7%.
The report said that the decline in transportation activities is an important reason for the sharp decline in global carbon emissions. At the peak of epidemic prevention in April, global carbon emissions from automobile and air transport fell by about half compared with 2019 levels, respectively, and by about 10% and 40% respectively by December.
