Academic institutions across the globe routinely sponsor large conferences. During the COVID-19 pandemic, many conferences have used all- or partially virtual formats. The conversion of the 2021 Consortium of Universities for Global Health (CUGH) conference, originally planned in-person for Houston, TX USA to an all-virtual format provided an opportunity to quantify the climate-related impacts of in-person versus virtual conferences. From the 2021 CUGH conference registration data, we determined each registrant’s distance from Houston. Using widely available, open-source formulas, we calculated the carbon footprint of each registrant’s round-trip drive or flight had they traveled to Houston. We assumed that registrants traveling more than 300 miles would have flown, with the remainder traveling by automobile. Of 1909 registrants, 1447 would have traveled less than 4000 miles, and 389 would have traveled more than 10,000 miles round trip. Total travel-related carbon emissions were estimated at 2436 metric tons of CO2, equivalent to the conservation of 2994 acres of forest for a year. Organizations can now readily quantify the climate cost of annual conferences. CUGH’s annual international conference, when held in-person, contributes significantly to carbon emissions. With its focus on promoting global health equity, CUGH may play a lead role in understanding the pros and cons for planetary health of in-person versus virtual conferences. CUGH and other organizations could routinely measure and publish the climate costs of their annual conferences.

量化国际会议的虚拟与面对面形式的气候效益

全球的学术机构经常赞助大型会议。在 COVID-19 大流行期间,许多会议都使用了全部或部分虚拟形式。2021 年全球健康大学联盟 (CUGH) 会议将原计划在美国德克萨斯州休斯敦举行的面对面会议转换为全虚拟形式,这为量化面对面会议与虚拟会议的气候相关影响提供了机会。根据 2021 年 CUGH 会议注册数据,我们确定了每个注册人与休斯顿的距离。使用广泛可用的开源公式,我们计算了每位注册人前往休斯顿的往返车程或航班的碳足迹。我们假设旅行超过 300 英里的注册人会乘坐飞机,其余的人乘坐汽车旅行。在 1909 名注册者中,1447 的行程不到 4000 英里,而 389 的往返行程超过 10,000 英里。与旅行相关的总碳排放量估计为 2436 公吨二氧化碳,相当于一年保护 2994 英亩森林。组织现在可以轻松量化年度会议的气候成本。CUGH 的年度国际会议在亲自举行时对碳排放做出了重大贡献。CUGH 专注于促进全球健康公平,可能在了解面对面会议与虚拟会议对地球健康的利弊方面发挥主导作用。CUGH 和其他组织可以定期测量和公布其年度会议的气候成本。与旅行相关的总碳排放量估计为 2436 公吨二氧化碳,相当于一年保护 2994 英亩森林。组织现在可以轻松量化年度会议的气候成本。CUGH 的年度国际会议在亲自举行时对碳排放做出了重大贡献。CUGH 专注于促进全球健康公平,可能在了解面对面会议与虚拟会议对地球健康的利弊方面发挥主导作用。CUGH 和其他组织可以定期测量和公布其年度会议的气候成本。与旅行相关的总碳排放量估计为 2436 公吨二氧化碳,相当于一年保护 2994 英亩森林。组织现在可以轻松量化年度会议的气候成本。CUGH 的年度国际会议在亲自举行时对碳排放做出了重大贡献。CUGH 专注于促进全球健康公平,可能在了解面对面会议与虚拟会议对地球健康的利弊方面发挥主导作用。CUGH 和其他组织可以定期测量和公布其年度会议的气候成本。当亲自举行时,会显着增加碳排放。CUGH 专注于促进全球健康公平,可能在了解面对面会议与虚拟会议对地球健康的利弊方面发挥主导作用。CUGH 和其他组织可以定期测量和公布其年度会议的气候成本。当亲自举行时,会显着增加碳排放。CUGH 专注于促进全球健康公平,可能在了解面对面会议与虚拟会议对地球健康的利弊方面发挥主导作用。CUGH 和其他组织可以定期测量和公布其年度会议的气候成本。
