Buildings and construction consume half of the world’s natural resources and about 40% of it's energy. The sector also accounts for a third of global greenhouse gas emissions.

This case study showcases the CircVol project in Turku, Finland, and its innovative circular solution to decrease carbon emissions and other lifecycle impacts of buildings and infrastructure. The clay-based material developed by the project can be used as an alternative for part of the estimated 100 million tons of rock needed for construction across Finland, limiting the extraction of virgin material as well as increasing the use of local materials in place of carbon-intensive imports. This case study was produced by ICLEI.
