Potsdam, Germany (dpa) - Restrictions linked to the coronavirus pandemic led to an 8.8-per-cent worldwide decline in carbon dioxide emissions in the first half of 2020, the Potsdam Institute for Climate Impact Research (PIK) said in a study released on Wednesday.

Measures imposed by national governments, which included border closures, curfews and other restrictions on movement, caused a 1.6-billion-ton reduction in CO2 emissions in the January-to-June period compared to the same period in 2019, the institute located outside of Berlin said.

Zhu Liu of Tsinghua University, the study's main author, said that the research showed a correlation between individual countries' lockdown measures and a reduction in CO2 emissions.

The study - which relied on data from Carbon Monitor, a website that tracks daily carbon dioxide emissions - showed that in April, the month that many countries first imposed lockdowns, the CO2 reduction reached 16.9 per cent on the previous year.
