Cornerstone is a voluntary and market-based certification system for the responsible extraction of aggregates. It provides a tool to provide encourage responsible practices in the province and to provide insight into the level to which a pit or quarry operates in a socially and environmentally responsible manner.
Through CSC’s certification process aggregate sites are independently evaluated against CSC’s Responsible Aggregate Standard. By building demand for products from sites that achieve certification CSC provides market incentive for aggregate operations that are willing to meet these requirements. At the same time it gives public and private purchasers the ability to influence operations through their buying decisions.
Our approach is based on international best practices and experience gained over two decades from successful certification programs in other resource and construction sectors (FSC – forestry, MSC – fisheries, LEED – building).
