According to the Proximity Study made in 2013 by BirdLife International of 425 HeidelbergCement mining sites in 20 European and Central Asian countries, more than 153 sites were identified to be located within 1KM of a Natura 2000 area, Important Bird Areas (IBA), International protected area or National protected area.

On a global scale, 28% of limestone active quarries and 22% of aggregates quarries managed by HeidelbergCement are located in or near areas designated for their high biodiversity value.

To integrate the biodiversity specificities of each site in the management of the quarry, HeidelbergCement has developed the concept of Biodiversity Management Plans in 2009. In addition, the Group has also created its own set of indicators to help quarry managers measure and control biodiversity before, during and after extraction periods.
