Government policies during the COVID-19 pandemic have drastically altered patterns of energy demand around the world. Many international borders were closed and populations were confined to their homes, which reduced transport and changed consumption patterns. Here we compile government policies and activity data to estimate the decrease in CO2 emissions during forced confinements.
At their peak in early April 2020, daily global CO2 emissions decreased by –17% (–11 to –25% for ±1σ) compared with the mean 2019 levels, with just under half of this total change occuring due to changes in surface transport. At their peak, emissions in individual countries decreased by –26% on average. Emissions rebounded to within 5% of mean 2019 levels (range 1% to 8%) in early June as countries lifted or weakened their confinement policies. The impact on 2020 annual emissions depends on the duration of the confinement, with a low estimate of –4% (–2 to –7%) if prepandemic conditions return by mid-June, and a high estimate of –7% (–3 to –12%) if some restrictions remain worldwide until the end of 2020. Government actions and economic incentives post crisis will likely influence the global CO2 emissions path for decades.
