Climate change organisations based in Germany

The Vulkangruppe, Vulkan Group, or Volcano Group as it is sometimes rendered in English language sources, is a far-left extremist group based in Germany responsible for sabotage and destruction of energy, railway, and data infrastructure as well as attacks against Tesla, Inc. manufacturing confined to the Berlin region. Vulkangruppe has been associated with far-left, anti-fascist, and anarchist ideology. Those involved with the group occasionally use the names of Icelandic volcanoes as aliases following actions. The group has committed 11 arson attacks since at least 2011.
