The case study evidence in this publication showcases existing solutions that could be implemented at scale. Through this report, WorldGBC demonstrates strategies that will help the built environment transition towards a closed-loop system and calls for mass-market collaboration to make our circular economy aspirations business as usual for all built assets.

This report not only provides a solid framework for all stakeholders in the built environment sector on how to create a circular value chain, but also offers a practical checklist of actions to ensure the circular-readiness of built environments, starting from manufacturing, design, construction, operation, retrofitting, deconstruction, until reuse and recycling. Cities and regions can make use of this paper to gain a better insight into key circularity concepts, trends, challenges and aspects of circularity along the built environment value chain. They can understand the roles and responsibilities of different stakeholders, acquaint themselves with other members of the circular built environment network from around the world, as well as finding example case studies of circular built environments from around the world. The comprehensive approach of this paper can help cities and regions not only in Mapping and Designing phases of CCRI Methodology but also in Implementing and Monitoring phases.
