Biodiversity indicators
In addition to the indicators recommended by the association of cement companies called “Cement Sustainability Initiative” (CSI) which belongs to the World Business Council for Sustainable Development (WBCSD), HeidelbergCement developed its own set of indicators.
The Group developed with the help of renown scientists a list of 10 indicators which practically helps the company to measure and control biodiversity in operating extraction sites. In addition these indicators help measure the successfulness of its restoration measures.
