European Green is a label for green electricity based on Guarantees of Origin (GoOs). It is meant to support the transition of European energy supply systems into one unified, interconnected and sustainable energy system so that a sustainable, ecologically sound and future oriented energy supply system for Europe can be established.

European Green incorporates a blend of several renewable energy sources from many European countries. To ensure diversity, any GoO-package sold under the European Green-label has to consist of energy from at least four different renewable sources and has to originate from at least four distinct countries. European Green is certified and audited by an independent auditor: theTÜV Rheinland GmbH.
