During the COVID-19 pandemic, many smaller conferences have moved entirely online and larger ones are being held as hybrid events. Even beyond the pandemic, hybrid events reduce the carbon footprint of conference travel and makes events more accessible to parts of the research community that have difficulty traveling long distances, while preserving most advantages of in-person gatherings.

While we have developed a solid understanding of how to design virtual events over the last two years, we are still learning how to properly run hybrid events. We present guidelines and considerations-spanning technology, organization and social factors-for organizing successful hybrid conferences.

This paper summarizes and extends the discussions held at the Dagstuhl seminar on "Climate Friendly Internet Research" held in July 2021.

在 COVID-19 大流行期间，许多小型会议已完全在线进行，而大型会议则作为混合活动举行。即使在大流行之后，混合活动也减少了会议旅行的碳足迹，并使那些难以长途旅行的研究团体更容易参加活动，同时保留了面对面聚会的大部分优势。

虽然我们在过去两年中对如何设计虚拟赛事有了深入的了解，但我们仍在学习如何正确举办混合赛事。我们提出了组织成功的混合会议的指导方针和考虑因素——跨越技术、组织和社会因素。

本文总结并扩展了 2021 年 7 月举行的 Dagstuhl 研讨会上关于“气候友好型互联网研究”的讨论。
