The event was organized by WBCSD, Arup and the Ellen MacArthur Foundation. It marked the launch of WBCSD’s report “The business case for circular buildings: Exploring the economic, environmental and social value”, and announced the upcoming Circular Building Design Toolkit, developed jointly by Arup and the Ellen MacArthur Foundation. The WBCSD report illustrates the economic benefits of circular economy solutions in the built environment alongside a broader value case, including environmental and social factors. The Circular Building Design Toolkit brings together strategies, case studies and tools for designing more circular buildings, meaning reduced waste and carbon for a healthier planet and healthier people. The session also touched on the potential of circularity to unlock the transition towards net zero carbon in the built environment, and to make use of nature-based solutions. Three main approaches were highlighted as essential: the shared economy, product material efficiency and recycling circulation as part of production. Participants also stressed the importance of creating demand to make better use of tools.


Approximately half of all extracted resources globally are used for the built environment, with 11% of global GHG emissions being attributed to the embodied carbon found in construction materials.

This session, organized by WBCSD, Arup and the Ellen MacArthur Foundation, will bring together a panel of high-level professionals to illustrate the opportunity of circular solutions in terms of innovation, new business models, CO2 reduction from materials, biodiversity protection and benefits for communities. Participants will learn how to make use of circular economy tools in the built environment and understand the business case.
