The Hambach forest occupation is the most important ecology-oriented anarchist resistance project in Germany and Europe. Anarchists in the Hambach forest are part of the national and transnational anti-coal and climate-justice movement. The forest occupation is the only direct strategic intervention for the transformation of the German energy system. The central principles of anarchist practice in the forest are decentralisation, voluntary association for direct action and a direct-democratic organisation. The success of the resistance has been enhanced by the occupiers' ability to connect forest occupation to societal goals and highlight the difference between sustainable and exploitative ways of producing and living.
