The drop in emissions was driven by COVID containment measures like lockdowns, restricted production and travel
Between 2019 and 2020, global carbon dioxide emissions experienced the largest single year-on-year decline ever recorded — 6.3 per cent — dwarfing dips during both the global financial crisis of 2008, and the estimated decline following the end of World War II.
If we could continue that trend every year, we'd be able to limit warming to around 1.5 degrees Celsius, according to the international team of scientists, who published their findings today in Nature Geoscience
"This tells you that the massive change we saw in the economy — in this case because we were shutting it down — an equivalent change needs to happen in the decarbonisation of the world," said study co-author Pep Canadell from the CSIRO.
"Those equivalent units in the economy that shut down [during COVID], those units need to be switched to the zero carbon economy."
