The CIRCULAR IMPACTS project website has been updated with an evidence library on the circular economy. The Circular Impacts online library created by Ecologic Institute centralized information related to the circular economy transition. The library helped policy professionals in conducting impact assessments on the transition to a circular economy. It was a useful resource for policy-makers, journalists, scientists, NGOs and anybody else interested in increasing their knowledge of circular-economy concepts. The library formed an integral part of the website and was an important project outcome.
