Die Erde vom Weltall aus gesehen.

Welcome to hacc_

hacc is a diverse group of creatures pursuing different projects. Currently some of our activities are hacc.voc and infra4future (see below).
Another project is hacc.csv, where csv stands for collaboration, science, visualization, and data. There are two local groups in Germany, located in Munich and Siegen.

Who we are

“Hackers Against Climate Change” originated as a series of self-organized sessions at 35c3. Since then we have worked with other climate activist groups, supplying them with technical knowledge, as well as trying to raise awareness for the current climate crisis in the hacker community.

Feel free to get in contact and join us on multiple channels, in a regional meetup, meet us at a Chaos event, or even start your own local group!


If you have an event and need someone to film or livestream it, maybe we have time and can help you! All our recordings and livestreams can be found on hacc.media; if we stream something live, you'll find us at live.hacc.media.

  • v-edge Congress 2020 in Munich
  • Filmed and live streamed several stage discussions and press conferences of other * for future groups (see hacc.media)
  • Livestreams from demonstrations for climate justice
  • Our own stage at the Remote Chaos Experience (rc3) 2020
  • Streaming infrastructure for the second and third editions of the Public Climate School by Students for Future

We provide and administrate server infrastructure for other climate justice groups.

  • cloud storage, chats, and forums
  • mumble.hacc.space: a voice-chat allowing groups to stay in contact while we can’t physically meet
  • if you need any, look around on the website linked above, write us, or just create an account!
