Our history

An innovation is born at BOKU
Unsere Geschichte startete im Jahr 2010 mit der Einrichtung des BOKU-CO2-Kompensationssystems. Die Universität für Bodenkultur Wien war damals und ist bis heute die einzige Universität, die eigene Klimaschutzprojekte umsetzt und fördert. Die ursprüngliche Idee war es, nicht vermeidbare Flüge von MitarbeiterInnen und Studierenden der BOKU zu kompensieren. Das erste Projekt, mit dem wir unser Wagnis starteten, war ein Waldaufforstungsprojekt in Nord Gondar, Äthiopien.
Growing external interest
Soon, private individuals and companies also began to take interest in the possibility of CO2-compensation. To date, we have been able to successfully launch numerous climate mitigation initiatives thanks to the many donations received. Our scientific advisory board has supported us in the selection of the projects from the very beginning.
Expansion towards climate neutrality
Insbesondere nach der Verabschiedung des Pariser Klimabkommens 2015 stieg auch die Nachfrage nach Klimaneutralität und wie man diese in Firmen und Organisationen erreichen kann. Daher haben wir mit Anfang 2020 unser Angebot erweitert: Wir bieten nun auch Beratung für Organisationen bei der Reduktion der eigenen Emissionen sowie Wissenstransfer im Bereich Klimaneutralität an. Mit diesem Erweiterungsprozess ging auch eine neue Namensgebung und der Launch einer neuen Website einher.


Our goals
