For HOCHTIEF, climate change has long been a fundamental and central focus in its Group-wide environmental sustainability strategy. The company aims to expand this strategic focus with the goal of supporting clients through projects in successfully adapting to climate change. HOCHTIEF has gathered data on greenhouse gases for over ten years and worked continuously on methodically improving Group-wide coverage, accuracy, and tracking to facilitate avoiding and effectively managing GHG emissions in all activities. These activities are enshrined in HOCHTIEF's position paper on climate change mitigation and adaptation and its transition plan for climate change mitigation (Net Zero Roadmap). The position paper on climate change mitigation and adaptation was coordinated with all operational units and applies Group-wide.

The GHG emission targets were approved by the Executive Board together with the Sustainability Plan 2025 as a fundamental commitment. These greenhouse gas reduction targets are based on climate scenarios and are science-based, developed with external experts in line with the 1.5 degree target in the Paris Climate Agreement on the basis of the requirements of the SBTi. However, they have not yet been externally verified. Decarbonization requires significant technological advancements, particularly in construction materials as well as machinery and equipment. We are very much dependent on our suppliers in this respect and will be working with them to help drive these advancements forward. Due to the strong interactions and cross-scope effects between the various decarbonization levers, the individual reduction contributions cannot be precisely estimated. The current status with regard to the targets directly reflects the progress of our transition plan.
