World carbon dioxide emissions declined by 7% in 2020, affected by the epidemic

Washington: A world hit by a closed-out epidemic this year cut its carbon dioxide emissions by 7%, the biggest drop yet, new preliminary figures show.
The Global Carbon Project, an official group of dozens of international scientists that monitor emissions, calculated that the world would have put 37 billion US tons (34 billion metric tons) of carbon dioxide into the air in 2020. This is less than 40.1 billion US tons. In 2019 (36.4 billion metric tons), according to a study published on Thursday in the Earth System Science Data Journal.
Scientists say the decline is mainly because people are living at home, traveling less by car and plane, and that emissions are expected to pick up after the epidemic ends. Ground transport makes up about one fifth of carbon dioxide emissions, the main man-made heat-trapping gas.
“Of course, lockdown is no way to deal with climate change,” the study said, with co-author Cornie Lequere, a climate scientist at the University of East Anglia.
Months ago a group of scientists predicted an emission drop from 4% to 7%, based on the progress of COVID-19. LeQuere stated that a second coronavirus wave and a decrease in continuous travel led to a reduction of up to 7%.
Emissions dropped 12% in the United States and 11% in Europe, but only 1.7% in China. This is because the second wave was lower in China than the first. In addition, China’s emissions are more industrial than other countries and its industry was less affected than transportation, LeQuere said.
The calculations – based on reports on details of energy use, industrial production and daily mobility – were accurately praised by outside scientists.
Even with the fall in 2020, the world averaged 1,185 tons (1,075 metric tons) of carbon dioxide into the air every second.
The final figures for 2019, published in the same study, show that emissions of the main man-made heat-trapping gas increased only 0.1% from 2018 to 2019, much smaller than the annual jump of about 3% a decade or two ago. Although emissions are expected to increase after the epidemic, scientists are wondering if 2019 will be the peak of carbon pollution, LeQuere said.
“We are definitely very close to an emissions peak, if we can put the global community together,” said UN Development Director Achim Steiner.
Chris Field, director of the Stanford Woods Institute for the Environment, believes that emissions will increase after the pandemic, but added “I am optimistic that we have some lessons learned that can help reduce emissions in the future.”
“For example,” he said, “as people love telecommuting a couple of days a week or realize that they don’t need a lot of business trips, we can see that future emissions in practice Decreases. ”
