Global Impacts of ‘Lockdown’
Global daily emissions fell sharply in 2020 as social confinement measures were introduced to slow the spread of coronavirus (COVID-19).
Regional Impacts
Reductions in emissions during January and February were predominantly driven by confinement in China.
International expansion of confinement measures led to deeper reductions in March and April.
Measures have persisted in many regions into 2021, with continued impacts on emissions.
Global Impacts on Emission Sectors
Reductions in emissions from surface transport, industry and power contributed most to the total reduction in daily emissions at the global scale.
Increases in residential emissions only slightly offset the reductions seen in other sectors.
Confinement had different impacts on total and sector-by-sector emissions reductions in different countries
