Porr: Construction group PORR has received the ÖGNI basic certificate for sustainable construction sites in building construction and civil engineering. This certificate confirms that PORR meets the essential sustainability standards as a fundamental requirement on all its construction sites. This includes, for example, the entire site organization, the analysis of environmental risks, and the development of concepts for noise and dust control. Resource conservation through the recording and monitoring of energy and water consumption on the construction site also plays a key role. Going forward, for new construction projects, PORR will only need to submit and have reviewed those aspects that cannot be generally standardized – such as the machinery used or project-specific measures for site organization, like communication processes. This significantly reduces the administrative burden and makes the certification process more efficient, transparent, and predictable.
Porr: weekly performance: -7.62%

Strabag: Construction group STRABAG will be testing intensively  a hydrogen-powered wheel loader from Liebherr over a two-year period, running it at least 50 hours per week. Fuels represent STRABAG’s largest source of CO₂ emissions – around 40 percent of total Group emissions are attributable to the diesel consumption of its construction machinery, commercial vehicles and passenger cars. "To become climate neutral by 2040, we need effective solutions – and converting our construction machinery to renewable technologies is an essential lever. We are pursuing our sustainability path consistently, science-based and open to all technologies. The test run of the hydrogen-powered wheel loader is an example of what sustainable operation and the decarbonisation of our large-scale equipment can look like," says STRABAG CEO Stefan Kratochwill.
Strabag: weekly performance: -4.27%
