COVID-19大流行正在影响人类活动,进而影响能源使用和二氧化碳(CO2)排放。在这里,我们根据近实时的活动数据对不同部门的国家级二氧化碳排放量进行了每日估计。关键结果是2020年上半年全球二氧化碳排放量(-1551 Mt CO2)与2019年同期相比突然减少8.8%。这种下降的幅度比以前的经济衰退或第二次世界大战期间更大。排放量减少的时间与每个国家的封锁措施相对应。到7月1日,随着封锁限制的放松和一些经济活动的重新启动,疫情对全球排放的影响有所减弱,特别是在中国和几个欧洲国家,但各国之间存在重大差异,美国的排放量继续下降,而冠状病毒病例仍在大幅增加。
The COVID-19 pandemic is impacting human activities, and in turn energy use and carbon dioxide (CO2) emissions. Here we present daily estimates of country-level CO2 emissions for different sectors based on near-real-time activity data. The key result is an abrupt 8.8% decrease in global CO2 emissions (−1551 Mt CO2) in the first half of 2020 compared to the same period in 2019. The magnitude of this decrease is larger than during previous economic downturns or World War II. The timing of emissions decreases corresponds to lockdown measures in each country. By July 1st, the pandemic’s effects on global emissions diminished as lockdown restrictions relaxed and some economic activities restarted, especially in China and several European countries, but substantial differences persist between countries, with continuing emission declines in the U.S. where coronavirus cases are still increasing substantially.
