WFH and the almost 100% shutdown off airline travel at the beginning of the pandemic resulted in nearly 0 change in CO2 emission and levels in the atmosphere.
It's a bit off topic but that didn't sound right to me.
According to the following it was a reduction but yes near zero in the context of total emissions. A few hundred million tonnes reduction ain't nothin none the less.
"plummeted from more than 1 000 Mt CO2 in 2019 to less than 600 Mt CO2 in 2020, in the context of the pandemic.
In 2023, aviation accounted for 2.5% of global energy-related CO2 emissions, "
Of course we shouldn't expect a couple of years of shutdown to significantly reverse 200 years of man-made atmospheric CO2 accumulation, but surely it would help stop the problem to get worse if the widespread WFH effort were sustained after the pandemic.
