“We have taken significant strategic steps in climate protection and sustainability over the past two years and implemented them consistently. The improvement in the CDP rating confirms we’re on the right track”, says PORR CEO Karl-Heinz Strauss. PORR improved its Climate Change rating from B to A-. In the Water category, PORR retained its B rating, while making improvements in specific subcategories.

Key measures include the implementation of a Group-wide sustainability strategy, the full calculation of the corporate carbon footprint, and a clearly defined decarbonisation plan. The plan provides for a reduction in emissions of 43% in Scope 1 and Scope 2, as well as 25% in Scope 3 by 2030 (baseline year 2024). PORR’s commitment to the Science Based Targets initiative (SBTi) was also taken into account in the assessment. In the area of Water, the expansion of the scenario analysis and improved data quality – such as through the use of water meters – also played a role. 

Measurable successes

With its Sustainability Strategy 2030, PORR achieved the following measurable successes already in the first year:

1. Significant reduction in emissions
   PORR reduced its direct emissions (Scope 1 and 2) by 22.5% and its upstream and downstream emissions (Scope 3) by 12.9%. With production output holding steady, emissions intensity decreased by 14.3%. Key drivers included the increased use of alternative fuels, the expansion of renewable energy, and lower energy consumption. 
    
2. Increase in energy efficiency and expansion of renewable energy
   PORR reduced its total energy consumption by 9.2% to 817.1 GWh. At the same time, the share of renewable energy rose significantly to 19.9% (2024: 7.7%). Measures include the increased use of photovoltaic systems and green electricity on construction sites, as well as optimising energy consumption and equipment usage.
    
3. Strengthening the circular economy 
   The internal recycling rate increased from 50% to 57%. This means that more than half of the recycled materials used came from PORR’s own recycling processes. This resulted in a reduction in the need for primary raw materials. At the same time, PORR is strengthening its independence from volatile raw materials markets and reducing procurement risks. Key levers include the processing of excavated materials, recycled asphalt, and the use of secondary construction materials. 

Expansion of sustainable portfolio

“The CDP rating shows that we are increasingly delivering our strategic objectives in day-to-day construction operations”, says PORR CEO Karl-Heinz Strauss. Sustainability is an integral part of PORR’s business model. In addition to clearly defined minimum standards, such as those for sustainable construction sites, the range of services is now being systematically expanded. The portfolio combines standardised solutions with tailored approaches for clients – ranging from CO₂-optimised planning and the use of low-emission materials through to energy-efficient construction sites, as well as demolition and recycling concepts. In this way, PORR is positioning itself as a provider of integrated sustainable construction services.

The non-profit environmental organisation CDP (Carbon Disclosure Project) is regarded as one of the world’s leading standards bodies for environmental reporting. More than 22,000 companies, representing over half of global market capitalization, disclose their environmental data through CDP. CDP ratings are internationally recognised as a benchmark for sustainability and climate management.
