As a member of the “Cement Sustainability Initiative” (CSI) which belongs to the World Business Council for Sustainable Development (WBCSD), HeidelbergCement has implemented in its Biodiversity Ambitions 2020 the following two KPIs:

  • KPI 1: Percentage of quarries under active exploitation with a restoration plan.
  • KPI 2: Percentage of sites with high biodiversity value (as defined according to GRI EN11) where biodiversity management plans are actively implemented*

*In order to calculate this we also collect data on the number of active quarries within, containing or adjacent to areas designated for their high biodiversity value, as defined by the GRI I guidelines.

In addition to these  indicators, HeidelbergCement developed in 2010 a set of additional habitat- and species-focused measures that local companies could use to monitor biodiversity on their sites and to evaluate the successfulness of their restoration actions.  

Indicators dedicated to habitats
