Fig. 2. Changes in the sectoral CO₂ emissions of China in 2020 and 2022 compared to those in 2019.

The 10-day moving average emission changes are shown for the power, industrial, transport, and residential sectors from 2019 to 2020 (A) and from 2019 to 2022 (C). The sector-specific CO₂ emission reductions during the 2020 lockdown [gray shading in (A)] and the 2022 lockdown periods [gray shading in (C)] are presented in (B and D), respectively. The numbers in (B) and (D) show the absolute emission reductions and relative changes in emissions (in brackets) for each sector. The pie charts show the contribution of each sector to the total emission reductions during the lockdown periods.
