Impact of the COVID-19 pandemic on the environment
The COVID-19 pandemic has had an impact on the environment, with changes in human activity leading to temporary changes in air pollution, greenhouse gas emissions and water quality. As the pandemic became a global health crisis in early 2020, various national responses including lockdowns and travel restrictions caused substantial disruption to society, travel, energy usage and economic activity, sometimes referred to as the "anthropause". As public health measures were lifted later in the pandemic, its impact has sometimes been discussed in terms of effects on implementing renewable energy transition and climate change mitigation.
