Key figures related to climate and resource protection (period under review: 2017)

Our core business has environmental effects: Building construction, transportation infrastructure projects, and the mining business all impact the soil, water, air, and climate and affect biodiversity. In light of this, environmental protection is afforded top priority throughout the HOCHTIEF Group.

We express our environmental indicators listed below in relation to Group work done in the year in question (coverage). The volume, type, location, and scope of the projects we have in progress during the year affect these indicators.
