The paper studies the effects of mitigation measures on environment during a pandemic. Various mitigation measures such as business closures have been imposed to reduce health risks. Such measures also limit economic activities and reduce emissions. Measures disproportionately affect the contact-intensive sectors such as the leisure and hospitality industry, as their economic activities involve more person-to-person interactions. Thus, the extent of emission reduction depends on the severity of a measure and the size of the contact-intensive sectors. Using data on business and restaurant closures, school closures and bans on gatherings across 50 U.S. states during the Covid-19 pandemic, an empirical analysis shows that emissions decrease more in states with a more stringent measure and a larger share of the contact-intensive sectors.

该论文研究了大流行期间缓解措施对环境的影响。已采取各种缓解措施，例如关闭企业，以降低健康风险。这些措施还限制了经济活动并减少了排放。措施不成比例地影响接触密集型行业，例如休闲和酒店业，因为它们的经济活动涉及更多的人与人之间的互动。因此，减排程度取决于措施的严厉程度和接触密集型行业的规模。利用 Covid-19 大流行期间美国 50 个州的企业和餐馆关闭、学校关闭和聚会禁令的数据，实证分析表明，在措施更严格且接触密集型行业所占份额更大的州，排放量减少得更多.
