The Ithaka Institute is an international open-source network for carbon strategies. It is a non-profit research foundation with the Headquarter in Europe having independent offices in Germany, the USA, and Nepal. In the last decade, Ithaka became a leading research collaboration for carbon sequestration and cycling through agronomic methods. The Institute is known for its expertise in production, post-production treatment, and use of biochar. Ithaka established the European Biochar Certificate and developed numerous biochar based products. We are engaged in several food security, soil fertility, and reforestation projects in Africa, Eastern Asia and Latin America.
