COVID-19-induced low power demand and market forces starkly reduce CO2 emissions

Abstract

The COVID-19 pandemic continues to strongly affect global energy systems. Global power sector CO2 emissions have shown a substantial decline, thanks to (a) the COVID-19-induced economic downturn and resulting reduction of electricity demand and (b) a decrease of carbon intensity of power generation as coal generation is decreased most strongly. These effects illustrate the opportunity for different policies to support a structural and accelerating decline of power sector emissions.
