Videoconferencing and teleworking have become indispensable for many public and private organizations since the appearance of COVID-19. However, the extent to which the pandemic may have a lasting effect on people’s daily life and work remains to be seen. Poor visual and acoustic quality of online meetings could reactivate old communication patterns in the long term. New technologies such as 6G and 3D holography, offering enhanced video quality and online experience, could further drive virtualization in communication. This article investigates the CO₂ mitigation potential resulting from the partial replacement of business travel by 6G-enabled 3D videoconferencing in Germany in 2030. The carbon footprint calculation combined with scenario analysis has shown significant results when direct and indirect energy effects are considered. In the different scenarios investigated, a virtual conference would cause between 0.2% and 0.9% of the emissions of a mean-distance conference trip taken by a German business traveler. Considering the mitigation potential of all German conference travel in 2030, emissions could be decreased by 2.1 MtCO₂eq (8.9%) and 20.5 MtCO₂eq (88.4%), respectively, compared to 2019 under conservative and optimistic assumptions. In terms of current national total emissions, increasing virtualization of conferences could contribute between 0.3% and 2.8% to the German mitigation efforts.

自 COVID-19 出现以来，视频会议和远程办公已成为许多公共和私人组织不可或缺的一部分。然而，大流行对人们日常生活和工作的持久影响程度还有待观察。从长远来看，在线会议的视觉和听觉质量差可能会重新激活旧的通信模式。6G 和 3D 全息术等新技术可提供增强的视频质量和在线体验，可进一步推动通信虚拟化。本文研究了 CO ₂2030 年德国支持 6G 的 3D 视频会议部分取代商务旅行所产生的缓解潜力。碳足迹计算结合情景分析显示，在考虑直接和间接能源影响时，结果显着。在调查的不同情景中，虚拟会议产生的排放量是德国商务旅行者进行的平均距离会议旅行的 0.2% 到 0.9% 之间的排放量。考虑到 2030 年所有德国会议旅行的减排潜力，排放量可减少 2.1 MtCO ₂ eq (8.9%) 和 20.5 MtCO ₂eq (88.4%)，分别与 2019 年在保守和乐观假设下相比。就目前的国家总排放量而言，增加会议的虚拟化可以为德国的减排工作贡献 0.3% 到 2.8%。
