The CEO question this OS answers
"How do we ensure our supply chain is resilient, responsible, transparent, and aligned with our sustainability, human rights, and business objectives?"
Modern supply chains are exposed to increasing environmental, social, geopolitical, regulatory, and operational risks. Organisations are increasingly accountable not only for their own operations, but for impacts occurring across suppliers, contractors, and extended value chains. The CSDDD, EUDR, and national laws (LkSG, Loi de Vigilance) have made this a legal obligation for many companies.
The purpose is to move from supplier management towards strategic value-chain stewardship - where suppliers become partners in sustainability transformation, resilience, and innovation.
Section 2 - CEO Takeaway
The transformation
From
"We manage suppliers based on cost, quality, and delivery."
