Welcome to the Hackers Against Climate Change Wiki!

"Hackers against Climate Change" is a preliminary name for a variety of people & working groups/action groups that gathered for the first time during the "Hackers against Climate Change" session at the 35th Chaos Communication Congress in Leipzig. A lot of info was compiled in a variety in pads, (also partially archived here). Three local groups organized under the HACC name: Munich, Siegen, and Canarias. There has been HACC related activity at 36C3 (documented on pads). Since COVID19 hit, we've had sessions at DiVOC, about them on pad.land.
