CSC Responsible Sourcing Certificate

A concrete, cement, or aggregates plant has been independently certified against the CSC responsible sourcing framework, covering management, environmental, social, and supply-chain criteria, at Bronze, Silver, Gold, or Platinum level.

• Low-carbon concrete claims — CSC certifies responsible sourcing and production practice, not the mix's embodied carbon, which needs an EPD.
• Claims about concrete supplied from the producer's non-certified plants.
• Structural or durability performance of the concrete.

Expiry matters — check the certificate is current.

Certification is per plant and per level — Bronze and Platinum represent very different performance.

CSC certification is recognised in some building rating schemes' responsible-sourcing credits (e.g. BREEAM Mat credits); recognition varies by scheme and region.
