Ecologic Institute organized the final conference of IN-STREAM from the 27 to 28th of September in Brussels. The conference summarized the research results of IN-STREAM and provided a forum for an intensive discussion with other parties involved in the Beyond GDP process, such as the European Environment Agency, the European Commission, the OECD, UNEP and the Global Footprint Network. The discussion covered a wide range of topics regarding how sustainability can be measured and produced important results on how to identify and quantify trade-offs between different dimensions of sustainability.
