Coronavirus lockdowns have caused a whopping 17% drop in global carbon emissions

Coronavirus lockdowns have caused a whopping 17% drop in global carbon emissions

The coronavirus lockdowns have had an “extreme” effect on daily carbon emissions, causing a whopping 17% drop globally during peak confinement measures by early April – levels last seen in 2006.

However, it is unlikely to last, according to a new analysis by an international team of scientists.

This is the first analysis to measure the pandemic-driven global drop in carbon dioxide (CO2) emissions from January to April of this year.

Carbon dioxide, emitted from burning fossil fuels such as oil, gas and and coal, is the greenhouse gas that's most responsible for global warming.

While the impact of lockdown measures is likely to lead to the largest annual decrease in emissions since the end of World War II, 2020 is still on track to be one of the five hottest years on record, and the study notes that these reductions are no “silver lining.”

Pandemic causing changes:Will an 'unprecedented decline' in carbon emissions help limit climate change?

The study was published in the peer-reviewed British journal Nature Climate Change.

Daily emissions decreased by 17%, or 17 million tonnes of carbon dioxide, globally during peak confinement measures in early April, dropping to levels last seen in 2006.

Professor Corinne Le Quéré of the University of East Anglia in the U.K. led the analysis. She said “population confinement has led to drastic changes in energy use and CO2 emissions. These extreme decreases are likely to be temporary though, as they do not reflect structural changes in the economic, transport, or energy systems."

“The extent to which world leaders consider climate change when planning their economic responses post-COVID-19 will influence the global CO2 emissions paths for decades to come," she said.

Some of the report's key findings include:

• The estimated total change in emissions from the pandemic amounted to 1,048 million tonnes of carbon dioxide through the end of April. The largest decrease in emissions occurred in China, followed by the U.S., Europe and India.

• In the U.S., California and Washington saw the biggest decline in emissions.

• Emissions from surface transport, such as car journeys, accounted for almost half (43%) of the decrease in global emissions during peak confinement on April 7.

• The impact of confinement on 2020 annual emissions is projected to be around 4 to 7% compared with 2019, depending on the duration of the lockdown and the extent of the recovery.
