RESPONSIBLE SOURCING CERTIFICATION:
Lionel Lemay is Director, Market Development - North America for the Concrete Sustainability Council (CSC). CSC manages the global responsible sourcing certification system for the concrete sector, covering the entire value chain, including the supply chain with cement and aggregates, ready-mix and precast producers. The certification evaluates companies across four key areas: environmental stewardship (reducing CO2 emissions, resource efficiency, biodiversity, circular economy), social responsibility (health & safety, human rights), governance (business ethics, transparency, legal compliance), and economic resilience. By meeting these criteria, certified companies can demonstrate their commitment to responsible sourcing and contribute to more sustainable construction. CSC certification is recognized by green building rating systems like LEED and Envision.
