Recently, according to media reports, due to the outbreak of COVID-19, the global economy has almost stagnation. The carbon dioxide emissions in 2020 may be the most decline since the Second World War. Rob Jaxon, Chairman of the Global Carbon Program, said: "Global carbon emissions may fall by more than 5% year-on-year in 2020. This will be the first decline since the 2008 financial crisis and the largest decline since the Second World War. . "
Rob Jackson pointed out that neither the collapse of the Soviet Union nor the various oil crises or savings and loan crises over the past 50 years have affected emissions as much as this epidemic.
But this improvement was made by closing factories, grounding flights, and tens of thousands of people forced to stay at home. Such an improvement may be short-lived, and it will not affect the concentration of carbon dioxide accumulated in the atmosphere for decades. Big.
Corinne Le Quere, a climate expert at the University of East Anglia in the United Kingdom, pointed out that this is not a structural change. Once the isolation period is over, emissions will return to their original levels. After the 2008 financial crisis, global greenhouse gas emissions have declined, but they have increased by 5.1% after the economic recovery.
Experts said that the epidemic caused a temporary drop in global carbon dioxide emissions, but it also posed a serious threat to long-term climate change actions, undermined global clean energy investment, and cut environmental targets for industrial emission reductions.
"Paris Climate Agreement" pointed out that the global average temperature rise should be controlled within 2 ℃, and efforts to control at 1.5 ℃. Climatologists have previously warned that in order to meet the temperature targets of the Paris Agreement, global emissions must begin to decline from 2020.
