在全球应对COVID-19大流行之际，全球能源格局发生了突然而突然的变化。作为现代文明的核心的传统化石燃料，由于严格的封锁和严格的防疫措施，大部分类别的消费量都在迅速下降。因此，这些变化在最近一段时间内为世界带来了各种环境效益。本文试图调查由于化石燃料消耗的减少而在这种不断发展的情况下实现的这些环境效益和逆转。本文采用生命周期评价工具对9项环境影响和1项能源影响进行了评价。这些影响包括臭氧形成（陆地生态系统）、陆地酸化、淡水富营养化、海洋富营养化、陆地生态毒性、淡水生态毒性、海洋生态毒性、土地利用、矿产资源稀缺和累积能源需求。研究结果表明，2019冠状病毒病给全球环境和生命周期能源需求带来了令人印象深刻的变化，与2019年相应的读数相比，2020年上述所有影响的削减约为11-25%。
As the world grapples with the COVID-19 pandemic, there has been a sudden and abrupt change in global energy landscape. Traditional fossil fuels that serve as the linchpin of modern civilization have found their consumption has rapidly fallen across most categories due to strict lockdown and stringent measures that have been adopted to suppress the disease. These changes consequently steered various environmental benefits across the world in recent time. The present article is an attempt to investigate these environmental benefits and reversals that have been materialized in this unfolding situation due to reduced consumption of fossil fuels. The life cycle assessment tool was used hereby to evaluate nine environmental impacts and one energy based impact. These impacts include ozone formation (terrestrial ecosystems), terrestrial acidification, freshwater eutrophication, marine eutrophication, terrestrial ecotoxicity, freshwater ecotoxicity, marine ecotoxicity, land use, mineral resources scarcity, and cumulative exergy demand. Outcomes from the study demonstrate that COVID-19 has delivered impressive changes in global environment and life cycle exergy demand, with about 11–25% curtailment in all the above-mentioned impacts in 2020 in comparison to their corresponding readings in 2019.
