Sustainability

The climate crisis is one of the greatest challenges of our time: the construction industry accounts for 38 per cent of global greenhouse gas emissions. As a leading construction technology group, we take our responsibility seriously. We build with and for people, want to be part of the solution and create real change. This means less impact on the environment and more benefit for society. We take a holistic view of sustainability and derive new ways of working.

More about ESG management at STRABAG

Our sustainability strategy covers the areas of the environment, social responsibility and sustainable corporate governance:

  • Environment

    We are significantly reducing our resource and energy consumption and focussing on the circular economy, biodiversity and ecosystems.

  • Social responsibility

    We promote the well-being of our employees, implement measures to protect human rights along the entire value chain and always work to create added value for society.

  • Sustainable corporate governance

    We take measures to ensure that we always act with integrity. To this end, we define responsibilities and establish clear processes for fair competition and sustainable corporate governance.

Work On Progress

At STRABAG, we don’t just talk, we take action. With our projects, we contribute to sustainable construction and develop innovative technologies together with strong partners. Our Work On Progress website highlights specific projects to show our progress towards climate neutrality by 2040 along the entire value chain.

Sustainable building materials and innovative products for a green future

roxit focuses on innovative building products and sustainable building materials to minimise the environmental footprint and promote the circular economy. Our portfolio includes hemp- and flax-based insulating materials for energy-efficient and environmentally friendly construction projects as well as timber construction and acoustic systems designed to optimise indoor climate quality. With these sustainable building systems, we contribute to CO₂ reduction in the construction industry.

  • Future-ready mobility solutions: hydrogen-powered and electric wheel loaders in real-world use

    To advance the decarbonisation of the construction industry, we are testing innovative drive technologies in our quarries. In Austria, roxit is testing a hydrogen-powered wheel loader at the Kanzelsteinbruch quarry in Gratkorn, which is expected to save 37,500 litres of diesel and around 100 tonnes of CO₂ annually. At the same time, an electric wheel loader is in operation in Slovenia, saving 19 tonnes of CO₂ annually while outperforming diesel models in both performance and operator comfort. In addition, a hydrogen fuel cell lorry is being tested at the Bohučovice quarry in the Czech Republic to further move heavy-duty transport toward climate neutrality.

  • Reallabor – Sustainable Building: Vienna’s centre for sustainable building

    In Vienna, roxit has opened the "Reallabor - Sustainable Building", an innovative research centre dedicated to resource-conserving construction methods. On 1,200 square metres, alternative building materials are being tested under real-world conditions to assess their potential. Areas of research include straw-based building boards and clay as well as insulating materials such as hemp, flax and sheep’s wool. The Reallabor project promotes the acceptance of climate-neutral building materials and supports our goal of relying exclusively on low-emission materials in the long term.

  • Research for the future: sustainable concrete

    roxit is actively engaged in the research and development of sustainable building materials, with a strong focus on advancing the circular economy. One key project explores the use of quarry by-products to generate valuable supplementary cementitious materials (SCM). Current efforts focus on analysing the raw materials to enable the development of low-clinker concretes in the short to medium term. In the long term, the goal is to establish a concept that closes raw material loops, minimises CO₂ emissions and improves material efficiency in order to actively contribute to environmentally friendly construction.

Circular economy at roxit

roxit understands the circular economy in the construction industry as the integration of ecological responsibility withe technical performance to enable economically efficient reductions in environmental impact. In the context of raw and building materials essential for construction, roxit provides support by increasing recycling rates and the reuse of secondary raw materials. A key technology within the circular economy is cold recycling, a low-CO₂ and economical on-site road rehabilitation method that eliminates the need for energy-intensive reheating in stationary asphalt mixing plants. This reduces transport routes, emissions and timelines for the benefit of the client and the environment. Solutions like these conserve resources while ensuring that construction projects remain technically and economically feasible.
