sustainability
As a company with over 6,000 employees, we take responsibility, for both the environment and our fellow human beings. We take this responsibility to heart.

Environment & Climate – Responsibility for Environment and Climate
We are actively committed to environmental protection and strive to reduce our ecological footprint. Our environmental strategy is an integral part of corporate management and is based on the requirements of ESRS, GRI, and the United Nations Sustainable Development Goals (SDGs).
Efficiency
We are dedicated to significantly reducing environmental impacts and actively promoting sustainable construction practices. Our focus is on optimising construction and operational processes to reduce energy and material consumption. Through targeted management of energy and resources, we continuously improve energy efficiency and reduce reliance on fossil fuels.
Comprehensive Approach
Our waste management is based on systematic separation and, where possible, direct reuse, with the aim of minimising processing efforts. By returning building materials to the production cycle, we strengthen the circular economy. Further, we also leverage modern technologies to enhance eco-efficiency.
Renewable energies are central to our energy policy: we invest in photovoltaic systems on company buildings, use heat pumps for heating, continuously reduce fossil-fuel-based systems in our machinery and vehicle fleet, and switch to electricity from certified sustainable sources. Additionally, we implement targeted measures to promote biodiversity, such as greening unused areas and protecting ecologically sensitive zones at our sites.
Active Environmental Management
We apply environmental management systems in accordance with ISO 14001 at all our facilities and construction sites. Local environmental requirements are systematically considered. To identify and minimise physical and transitional risks, we regularly conduct climate risk analyses, the results of which inform our strategic planning and investment decisions.
Monitoring and Reporting
Our environmental objectives are measurable and reviewed annually. Progress is disclosed as part of our sustainability reporting and verified through audits.
