Workshop: “The right data for the best policies: What data is needed to support effective circular policy in the building sector?”, 6 March 2018, ecobuild, London

The workshop ‘The Right Data for the Best Policies’ at ecobuild 2018 in London was an excellent opportunity to learn from experiences in both the public and private sectors across Europe. Participating in a panel discussion were Clare Ollerenshaw (Circular Economy Manager and lead of the Circular London team at the London Waste & Recycling Board, U.K.), Ivana Kildsgaard (Sustainability Manager at LINK arkitektur, Sweden), Susan Schnadhorst (Senior Environmental  and Sustainability Advisor (SHE) at Osborne, U.K.) and Wim Debacker (Transitioneer and circular built environment researcher at VITO, Belgium). The session was moderated by Jackie Sharp (Senior Sustainability Advisor at BRE (Building Research Establishment).

The discussion was rich and dived into questions like: what have we learned from past experiences with data collection, why is data needed to make policy effective, what are the potential sources of data for policy purposes, and how can we make data collection a success? Participants agreed that there’s a need for data to provide evidence that the circular economy can work at a greater scale. Such data is important to convince policy makers to continue forward on the path towards a circular economy, but such evidence is also needed to convince companies of the business case for making the change to a circular business model.

Concerning existing data gaps and future sources of data, the work of architects and designers was proposed by panelists as a possible source of data, but it was recognized that there’s a need to connect data created during the design phase with up-stream policy needs. BIM was suggested by participants as a possible source for providing data to policy makers up-stream. Similarly, BIM and technology advances were proposed as a way to ensure that the robustness of data improves.

Past efforts for data collection on waste has not always been robust. Correctly targeting all relevant actors in data collection schemes was also identified as key to successfully collect broad spectrum data for policy purposes. More than one category of actor must contribute to data collection.  The economy involves all actors, and thus data on the circular economy should be seen a macro resource that can connect the dots and make connections between projects and contribute to overall reduction of materials. To make robust data collection possible, participants proposed a place for both top-down and bottom-up approaches, as well as both regulations and incentives.

These and other conclusions from the workshop will act as input for the BAMB project’s work on policies and standards. Highlights from the discussion will contribute to the drafting of recommendations for future policies and standards, to be made public in early 2019.
