Fig. 1: Global daily emissions changes in 2019 and 2020.
From: Global patterns of daily CO2 emissions reductions in the first year of COVID-19

a, Daily global CO2 emissions trends in 2019 and 2020. Real emissions data are shown as solid black lines in the form of a seven-day running mean. The dotted line represents simulated baselines in 2020 (see Methods for more details). b, Global daily CO2 reduction in 2020 compared with 2019 and the global daily new death cases of COVID-19 in 2020. The green area shows the seven-day running mean of daily CO2 emissions change in 2020 compared with 2019. The daily new death numbers of COVID-19 (ref. 38) are shown in blue areas and are used as indicators for the progress of the COVID-19 pandemic.
