From the Abstract: The COVID-19 [coronavirus disease 2019] pandemic resulted in stay-at-home policies and other social distancing behaviors in the United States in spring of 2020 This paper examines the impact that these actions had on emissions and expected health effects through reduced personal vehicle travel and electricity consumption Using daily cell phone mobility data for each U S county, we find that vehicle travel dropped about 40% by mid-April across the nation States that imposed stay-at-home policies before March 28 decreased travel slightly more than other states, but travel in all states decreased significantly Using data on hourly electricity consumption by electricity region (e g , balancing authority), we find that electricity consumption fell about six percent on average by mid-April with substantial heterogeneity Given these decreases in travel and electricity use, we estimate the county-level expected improvements in air quality, and therefore expected declines in mortality Overall, we estimate that, for a month of social distancing, the expected premature deaths due to air pollution from personal vehicle travel and electricity consumption declined by approximately 360 deaths, or about 25% of the baseline 1500 deaths In addition, we estimate that CO2 [carbon dioxide] emissions from these sources fell by 46 million metric tons (a reduction of approximately 19%) over the same time frame COVID-19 (Disease);Epidemics;Public health;Social Distancing;Greenhouse gases
