The global volume of carbon dioxide emissions in the first half of 2020 decreased by a record 8.8%, writes Nature Communications.
Global greenhouse gas emissions fell by about 8.8% in the first half of this year, a record high since the 2008 crisis, the 1979 oil shock and World War II.
The largest emission reductions are associated with the land transport sector. Globally, associated emissions have decreased by about 40% thanks to work from home and other measures to combat the epidemic. In comparison, the decline in emissions from industry and energy was 22% and 17%.
Daniel Kammen, one of the study authors, professor at the University of California at Berkeley in the United States.
The spread of coronavirus infection has led not only to an overload of healthcare systems in dozens of countries around the world, but also to a sharp decrease in industrial production, automobile traffic and many other sources of CO2 and other greenhouse gases.
The first observations of this decline, which scientists carried out this summer, showed that greenhouse gas emissions decreased by about 17% compared with winter and early spring 2019. Scientists expect global CO2 emissions to fall by about 4.4-5.3% over the entire current year.
According to Kammen and his colleagues, this is a record value in the entire history of mankind, including the drop in industrial production and related emissions that occurred due to the largest military conflicts and economic crises.
