China's CO2 emissions were down by 25% from February 3 to March 1 due to Coronavirus shutdown




From February 3 to March 1, CO2 emissions were down by at least 25% because of the measures to contain the coronavirus, according to the Center for Research on Energy and Clean Air (CREA), an air pollution research organization.

As the world's biggest polluter, China contributes 30% of the world's CO2 emissions annually, so the impact of this kind of drop is huge, even over a short period. CREA estimates it is equivalent to 200 million tons of carbon dioxide -- more than half the entire annual emissions output of the UK.

"As a measure that took place effectively overnight, this is more dramatic than anything else that I've seen in terms of the impact on emissions," said Lauri Myllyvirta, lead analyst at CREA.

But while lockdown measures designed to stem the spread of the virus have caused a momentary uptick in China's pollution levels, experts warn that when the county starts to reboot its economy the toxic chemicals could up to higher levels than before the epidemic hit.
