What is your sustainability and responsible-sourcing approach?

G4S sources raw material through contracted supply bases with a traceability ledger (raw-material source through processing to the finished product). Buyers can request a supply-chain / origin declaration and (for dedicated lots) organic certification. We aim for transparent, documentable sourcing rather than vague natural claims.
