The actions in the transition plan can be thematically assigned to four main decarbonization levers: Cooperation with Clients and Partners, Low emission construction materials, Increasing Efficiency and Effectivity, and Renewable Energy. These actions address HOCHTIEF’s main emission sources and pave the way for continuous reduction of GHG emissions in all scope categories. Responsibility for implementation lies with the operational units, and progress is tracked against targets. The actions extend across all business activities and apply to all operating regions.

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.

The actions in the transition plan are implemented in close collaboration with clients and stakeholders, with responsibility lying with operational units.
