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.

Collaboration with clients and business partners is essential for implementing sustainability measures. This includes proposing project-specific, low-emission solutions, promoting sustainable design, and increasing the proportion of projects with early contractor involvement. The collaboration drives the transformation of the construction and infrastructure sector toward greater sustainability. Measures include promotion of sustainable design, circular design, project certification, and sustainable travel solutions.
