Creating Local Economies with Complete Cycling of Concrete

Session hosted by WorldGBC and the Circular Buildings Coalition

The Circular Buildings Coalition (CBC) is an initiative by World Green Building Council (WorldGBC), Metabolic, Circle Economy Foundation, World Business Council for Sustainable Development (WBCSD), Ellen MacArthur Foundation and Arup to accelerate the transition to a circular economy in the European Built Environment. Supported by Smith Innovation and Laudes Foundation, we bring together stakeholders from the built environment to overcome barriers and embrace sustainable practices.

The CBC estimates that circular and low-carbon strategies could reduce CO₂e emissions in the EU construction sector by up to 4.15 gigatonnes, helping to keep the 2°C global warming target within reach. Among these strategies, those focused on decarbonizing and recycling concrete are identified as having the highest potential impact.

CBC explored the main challenges and opportunities in increasing the circularity of concrete and reducing its environmental impact, with different stakeholders of the sector: academics, city authorities, designers, manufacturers, designers and consultants. Their reflections can be found in the deep dive ‘Creating Local Economies with Complete Cycling of Concrete’, published in May 2025.

This webinar will highlight the key findings of the publication and feature a dialogue with leading experts to explore the latest innovations in concrete sustainability. The session will also discuss practical strategies for advancing sustainable practices in the field.
