Abstract: The construction sector has long recognised the decisive role of the various phases of the building lifecycle in the global environment. The identification of the construction environmental impacts is a significant progress for the development of a sustainable supply chain related to the raw material consumption and the construction and demolition waste (C&DW) generation. In this sense, circular economics' principles have solid potential to address these challenges in all European Union countries and especially in France. Nowadays, input-output (I/O) modelling covers the analysis of waste generation (WIO). As the supply chain of the building construction process is complex and has several related activities, and in a preliminary moment a conceptual model was developed, this approach provided an assessment of the mitigation actions of C&DW generation in France. This evaluation shows some positive waste reduction of several materials in the construction process, especially in concrete, metal, rock/rubble and sand/soil. However, the same study exhibits that even materials that can be recycled in the construction process, e.g., concrete, plastic, and metal, might not have a positive waste reduction during demolition due to the lack of proper waste separation and contamination during the process.
