Initiated by the Cement Sustainability Initiative (CSI), a project of the World Business Council for Sustainable Development (WBCSD), international partners from the concrete sector began a responsible sourcing certification system to make the concrete and cement sector more sustainable and to improve transparency. 


Having been available online since 1 January 2017, the CSC certification system is designed to help concrete, cement and aggregate companies obtain insight in the level to which a company operates in an environmentally, socially and economically responsible way. The CSC certification system covers the raw materials, its source or provenance, its manufacture and a range of economical, social and environmental impacts.

The CSC certification system consists of an operational manual and assessment criteria with guidance on their application. A typical certification process includes a number of easy steps, is applicable to all sizes of concrete, cement and aggregate companies, and comprises four levels: bronze, silver, gold and platinum.

The CSC aims to improve transparency of the concrete sector, highlight the essential role of concrete in creating a sustainable construction sector by getting recognition in 'green' procurement government policies and building rating systems.
