“The uncertainty ranges represent the full range of our estimates. Changes are relative to annual mean daily emissions from those sectors in 2019 (Methods). Daily emissions are smoothed with a 7-d box filter to account for the transition between confinement levels. Note the different ranges on the y axes in the upper and lower panels.”
