PORR CEO Karl-Heinz Strauss: “To take sustainability seriously, you also have to prove it. Our figures show that we can successfully reduce emissions, use resources more efficiently, and deliver economic growth at the same time. For us, sustainability is an integral part of our business model”.

With the ESG strategy presented in 2025, PORR is pursuing 18 measurable targets by 2030, underpinned by 55 concrete measures. In the first year of implementation alone, it is clear that 13% of the measures have been fully integrated, with a further 71% currently being implemented. Sustainable business practices and financial success go hand in hand at PORR. The combined 2025 Annual and Sustainability Report shows that PORR has not only achieved outstanding results in terms of revenue and order volumes, but is also on the path to success when it comes to ESG.

1. Significant reduction in emissions 
   PORR has reduced its direct emissions (Scope 1 and 2) by 22.5% and its value chain emissions (Scope 3) by 12.9%. The company is therefore already on track in the first year towards its targets defined in 2024 within the framework of the Science Based Targets initiative (SBTi), which provide for a reduction of 43% (Scopes 1 and 2) and 25% (Scope 3) by 2030. The main drivers were the increased use of alternative fuels, the expansion of renewable energy and a reduction in energy consumption. Emissions intensity decreased by 14.3% even as production output remained stable.
    
2. Energy efficiency increased and renewable energy expanded 
   PORR managed to reduce its total energy consumption by 9.2% to 817.1 GWh. At the same time, renewable energy as a share of total energy consumption increased significantly to 19.9% (2024: 7.7%). Measures include greater use of photovoltaics and green electricity on construction sites, as well as the optimisation of energy consumption and equipment use.
    
3. Circular economy strengthened
   The internal recycling rate was increased from 50% to 57%. This means that more than half of the resources in the PORR cycle originate from internal recycling. This has led to a fall in demand for primary raw materials. At the same time, PORR is strengthening its self-sufficiency from volatile raw material markets and reducing procurement risks. Key levers include the processing of excavated material and the use of recycled asphalt and secondary construction materials.
    
4. Percentage of women at PORR increased
   The share of women at PORR rose to 17.0%. A positive development is also evident in management positions, with an increase to 16.4% (2024: 15.5%).
    
5. Sustainable construction site as new standard
   In 2025, PORR became the first construction company in Austria to receive the ÖGNI basic certificate for sustainable construction sites in both building construction and civil engineering. The approach is being gradually implemented as a new PORR minimum standard on all construction sites and systematically embeds sustainability criteria into construction work.

Positioned as a provider of integrated, sustainable construction services 

This momentum is continuing: PORR is expanding its range of sustainable services. In concrete terms, this involves the combination of clear minimum standards in line with the basic certificate for sustainable construction sites and customised solutions for clients that combine environmental and economic requirements. The range extends from CO₂-optimised design and build solutions to emission-reduced materials, energy-efficient construction sites, innovative logistics solutions, as well as deconstruction and recycling concepts.

PORR is thereby positioning itself as a provider of integrated, sustainable construction services. Strauss: “We are taking a targeted approach to growing our portfolio in sustainable construction so that – together with our customers – we can reduce emissions, decrease resource consumption and cut costs across the entire life cycle of a construction project”.
