Global emissions will decline faster than any record time as COVID-19 hits the economy

According to researchers, daily emissions estimated from data such as electricity generation in 31 countries, motor vehicle traffic in more than 400 cities, and mining and industrial production in 62 countries are 16.9 compared to April 2019. % Decreased.

Among the major sectors, the blockade restricted the movement of people and reduced it by 40%, resulting in transport recording the largest decline in emissions. Within that group, aviation emissions plummeted by almost 44%, a slight acceleration in July.

Estimates were released the day after the International Energy Agency predicted that annual emissions in 2020 would be about 7% less than in 2019. The decline in fossil fuel usage is exacerbated by the constant decline in renewable energy, especially sunlight. ..

In the first half of this year, US emissions fell 13.3%, while the European Union and the UK fell 12.7%.

The number of people in India decreased by 15.4%, while the number of people in China, where the coronavirus first appeared, decreased by only 3.7% due to the recovery of the country’s economy.

Researchers have warned that the decrease is temporary and likely to be negligible compared to the long-term increase in atmospheric concentrations of carbon dioxide and other gases.

“The reduction in CO2 is unprecedented, but the reduction in human activity is not the answer,” said Hans Joachim Shern, founder of the Potsdam Institute for Climate Impact Research and one of the authors of the report. Hoover says.

“Instead, we need structural and transformative changes in our energy production and consumption systems,” says Professor Shelne Hoover.

“Individual behavior is certainly important, but what we really need to focus on is reducing the carbon strength of the global economy.”

Australia’s gasoline emissions fell 15% to 13.1 million tonnes and aviation emissions fell 44% to 4.7 million tonnes between January and June, according to data collected by consultancy Ndevr Environmental. did.

“What is really worrisome in the report is the strong recoil effect of the lack of structural change,” said Ritchie Melzian, director of the Climate Energy Program at the Australian Institute.

“This is especially the case in Australia, where there is no national policy to reduce pollution from transportation.”

Pep Canadel, executive director of the Global Carbon Project, said dust, smoke and other environmental issues have been tracked and reported on the use of satellites and other technologies, but no greenhouse gases have been reported until recently. It was.

“By having a more real-time system, we are strong and immediate to society and government about the evolution of our carbon emissions and the sectors that are intentionally, that is, the sectors that are most contributing or most affected by climate mitigation. (Provides feedback on) or unintentional (such as COVID-19) pandemic) changes in the energy system. “
