Your source looks at 2020 emissions, which is TRUE, but 2020 was covid shutdowns. I've seen somewhat-reliable estimates of 2-7% reduction in CO2-equivalent emissions. (If you look at 2019, it was remarkably about equal to 2018 after many years of increase.)

But 2021 was the biggest (full year) of emissions ever, more than covering the 2020 decrease. I don't know of any resources that track quarterly emissions, so I don't know if we can see whether 2022 is on-pace for another record year. Perhaps the price of oil reduced usage enough to reduce emissions this year compared to last, but I won't hold my breath.
