CO2 emissions show biggest ever drop in the first half of this year

-

London, 18: Global carbon dioxide emissions fell by 8.8% in the first six months of this year, the biggest drop for a first half-year period, due to the effects of Coronavius­related restrictio­ns, a study showed on Wednesday.

Research published in the journal Nature Communicat­ions by a group of scientists from China, France, Japan and the US, said emissions fell by 1,551 million tonnes or 8.8% in the first half of the year, compared to the same period last year. The 8.8% reduction represents largest ever fall in emissions over the first half year, larger than for any economic downturn.

than the annual decrease during World War II, although mean emissions are much bigger now than at that time.

The scientists used data based on real-time activity and analysed the daily, weekly and seasonal trends of CO2 emissions before and after the Covid-19 pandemic and the economic downturn it triggered.

This spring, government­s around the world imposed lockdowns to contain the Covid-19 pandemic which curtailed energy use for industrial production and transport. This resulted in greenhouse gas emissions declining.

Warmer-than-usual weather across much of the northern hemisphere also

WARMER-THAN-USUAL WEATHER across much of the northern hemisphere also meant that emissions were somewhat lower than they would have been in the same period of last year.

meant that emissions were somewhat lower than they would have been in the same period of last year. The study said the fall in daily CO2 emissions was most pronounced in April when the toughest restrictio­ns were in place. Emissions began to recover in late April and May as economic activity resumed in China and Europe. But falls in transport-related emissions persisted.

“By July 1, the pandemic’s effects on global emissions diminished as lockdown restrictio­ns relaxed and economic activities restarted, in China and many European countries,” the paper said. “However, substantia­l difference­s persist between countries, with continuing emission declines in the US where Covid cases are still rising.”
