WS 2: Sustainable Sourcing of Construction Materials

Workshop Chair: Bernard Mathieu, Head Sustainable Development of LafargeHolcim
Date and time: Tuesday 24, 11h00 – 13h00
Room: 4


Population growth & increased urbanization will drive the demand for construction materials. Simultaneously the public sensitivity for responsible sourcing of products and services is also rising. It is therefore key that construction materials are sourced responsibly, triggering improvement not only of the certified construction product, but also positively influencing the entire supply chain.

What will we talk about?

During the workshop we will present the journey the Concrete Sustainability Council (CSC) has undertaken to develop the first comprehensive label for concrete, cement and aggregate and, engaging with the audience, we’ll ask our panellists to discuss about:

  • Why responsible sourcing certifications are becoming increasingly important?
  • What are the essential challenges of responsible sourcing of construction materials and how should these questions be addressed?
  • What is the market expectation when looking at responsible sourcing of materials?

Join us! We want to hear your feedback and proposals on how to trigger responsible sourcing of construction materials.
