Climate, with covid-19, global CO2 emissions drop by 17%

This is supported by a study published in Nature Climate Change by an international team led by the School of Environmental Sciences of the University of East Anglia. They said we have returned to 2006 levels, but are unlikely to last without effective climate policies.

"The global lockdown from Covid-19 has had an" extreme "effect on daily carbon emissions, but is unlikely to last." In 2019, the world had emitted around 100 million tons of CO2 per day by burning fossil fuels and producing cement. At the beginning of April 2020 it dropped to 83 million tons per day, with a drop of 17% (range: from -11% to -25%).

This is supported by the report "Temporary reduction in daily global CO2 emissions during the COVID-19 forced confinement", published in Nature Climate Change by an international team of researchers led by Corinne Le Quéré of the School of environmental sciences of the University of East Anglia.

"Government policies during the COVID-19 pandemic have drastically altered patterns of energy demand around the world. Many international borders were closed and populations were confined to their homes, which reduced transport and changed consumption patterns. Here we compile government policies and activity data to estimate the decrease in CO2 emissions during forced confinements" we can read in the report. According with the research, emissions in individual countries decreased by –26% on average. The impact on 2020 annual emissions depends on the duration of the confinement, with a low estimate of –4% (–2 to –7%) if prepandemic conditions return by mid-June, and a high estimate of –7% (–3 to –13%) if some restrictions remain worldwide until the end of 2020. Government actions and economic incentives postcrisis will likely influence the global CO2 emissions path for decades, conclude the study.
