BACKGROUND
The health care sector contributes substantially to carbon emissions. Estimating the carbon emissions of an event can help determine its climate impact. This study calculates the carbon footprints of the 2019 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting and the 2019 Pediatric Orthopaedic Society of North America (POSNA) Annual Meeting.
METHODS
Data regarding attendance volume, geographic origin of attendees and vendors, hotel room nights, event space, and duration of meetings were obtained from AAOS and POSNA. Data were entered into an online calculator designed to measure the carbon footprint of large events (www.terrapass.com).
RESULTS
The AAOS 2019 annual meeting was attended by 29 448 people, requiring 66 000 hotel room nights and 2 308 800 ft2 of convention center space for 5 days. We estimated 7179 short, 8374 medium, and 13 421 long-haul round-trip flights. The POSNA 2019 annual meeting was attended by 1103 people, requiring 1932 hotel room nights and 52 100 ft2 of convention center space for 4 days. We estimated 501 short, 280 medium, and 280 long-haul round-trip flights. The AAOS 2019 meeting emitted 26 075 metric tonnes of carbon dioxide equivalents (COe), while the POSNA 2019 meeting emitted 544 metric tonnes. Eighty-one percent of the carbon emissions from AAOS and 80% from POSNA came from flight travel alone. Carbon neutralization of in-person AAOS and POSNA annual meetings would require carbon-offset purchases of approximately $273 700 and $5700, respectively.
CONCLUSIONS
Annual orthopaedic meetings contribute to climate change through their large carbon footprint. Leaders in the field of orthopaedics should consider strategies to mitigate the impact of such meetings, examples of which include transitioning to hybrid formats when appropriate and by purchasing carbon offsets for essential in-person participation.
KEY CONCEPTS
1)Calculating the carbon footprint of an event estimates its total carbon dioxide emissions to help determine how to reduce its climate impact.2)The AAOS 2019 meeting emitted 26 075 metric tonnes (MT) of carbon dioxide equivalents (COe), while the POSNA 2019 meeting emitted 544MT, with ∼80% coming from air travel alone.3)Carbon neutralization of in-person AAOS and POSNA annual meetings would require carbon-offset purchases of approximately $273 700 and $5700, respectively.

背景
医疗保健部门的碳排放量占比很大。估算某一活动的碳排放量有助于确定其对气候的影响。本研究计算了2019年美国骨科医师学会（AAOS）年会和2019年北美小儿骨科学会（POSNA）年会的碳足迹。
方法
从AAOS和POSNA获取了与会人数、参会者和供应商的地理来源、酒店入住夜数、活动场地以及会议时长等数据。这些数据被输入到一个旨在测量大型活动碳足迹的在线计算器中（www.terrapass.com）。
结果
2019年AAOS年会有29448人参加，为期5天，需要66000个酒店入住夜以及2308800平方英尺的会议中心空间。我们估算有7179次短途、8374次中途和13421次长途往返航班。2019年POSNA年会有1103人参加，为期4天，需要1932个酒店入住夜以及52100平方英尺的会议中心空间。我们估算有501次短途、280次中途和280次长途往返航班。2019年AAOS会议排放了26075公吨二氧化碳当量（COe），而2019年POSNA会议排放了544公吨。AAOS会议81%的碳排放和POSNA会议80%的碳排放仅来自航空旅行。对AAOS和POSNA的线下年会进行碳中和分别需要购买约273700美元和5700美元的碳抵消额度。
结论
骨科年会因其巨大的碳足迹而对气候变化有影响。骨科领域的领导者应考虑采取策略来减轻此类会议的影响，例如在适当的时候过渡到混合模式，并为必要的线下参会购买碳抵消额度。
关键概念
1）计算活动的碳足迹可估算其二氧化碳总排放量，以帮助确定如何减少其对气候的影响。2）2019年AAOS会议排放了26075公吨（MT）二氧化碳当量（COe），而2019年POSNA会议排放了544公吨，其中约80%仅来自航空旅行。3）对AAOS和POSNA的线下年会进行碳中和分别需要购买约273700美元和5700美元的碳抵消额度。
