Abstract: BRAINPOoL was a 2.5 year project funded by the EU FP7 funding stream to understand and explore the barriers to the use of Beyond GDP indicators in policy-making, and to identify opportunities to accelerate that use. The project involved a broad range of activities including a review of Beyond GDP initiatives, interviews with Beyond GDP indicator developers and the policy-makers and politicians who the indicators are intended to be used by, seven case studies looking at different institutional settings and how Beyond GDP indicators could be advanced, and various workshops and seminars. This paper will present the key lessons from this research for the degrowth community, and explore the synergies and tensions between the degrowth and Beyond GDP communities as they currently stand. It argues for a re-engagement, and linkage of research agendas.
