Fig. 4: Correlation matrixes of five indicators during 1 March~31 May 2020 and 1 October~31 December 2020.
From: Global patterns of daily CO2 emissions reductions in the first year of COVID-19
a, 1 March–31 May 2020. b, 1 October–31 December 2020. CO2, daily CO2 changes in 2020 compared with the simulated baseline emissions, which combine the daily emissions patterns in 2019 and historical sectoral trends; D, the daily new death cases of COVID-1938; SI, the stringency index of government responses to COVID-1939; GR, the duration spent at places of residence40; E, the daily changes of power demand in 2020 compared with the same day in 2019. These five indicators are the averages of the United States, India, the United Kingdom, France, Germany, Italy, Spain, Russia, Brazil and Japan. The daily averages of the five indicators during these two periods are shown in Extended Data Table 1. Gradient colors indicate negative strong relationship (red) through no relationship (yellow) to positive strong relationship (green).
