Sustainability Certifications

Image f. Sustainability Certifications

In recognition of the comprehensive steps that HLRS has taken to improve its environmental sustainability, the center has achieved multiple formal certifications for environmental and energy management. 

HLRS's systems for environmental and energy management cover all levels of the organization, addressing topics such as energy usage, resource consumption, and waste disposal. Activities that have negative impacts for the environment or human health are avoided, while employees across the organization are involved in identifying and implementing opportunities for improving environmental performance. In addition, these certifications recognize policies at HLRS that include:

  • considering environmental impact in all purchasing decisions
  • improving energy efficiency across the center's operations
  • supporting advanced research that will lead to widespread sustainability gains in domains such as transportation, energy, and climate
  • minimizing waste and avoiding use of environmentally damaging materials
  • reusing resources, including heat generated during operation of its HPC systems
  • promoting sustainability improvements among its peers
  • maintaining a work environment that promotes the health and well-being of employees and their families

Eco-Management and Audit Scheme (EMAS)

This system for voluntary environmental management, developed by the European Community, is the most demanding system for environmental management worldwide. HLRS was the first high-performance computing center to qualify for EMAS certification. Organizations that achieve EMAS certification commit themselves to maintain stringent environmental standards, to continually improve their environmental performance, to participate in regular reviews by an environmental auditor, and to publish an environmental statement. Learn more about EMAS.


ISO 14001 (Environmental Management)

ISO 14001 is an internationally recognized standard for the implementation of a comprehensive sustainability management system.  ISO 14001 certification is a central component of EMAS. In contrast to EMAS, this standard does not detail specific requirements for environmental performance and does not require an environmental statement. Learn more about ISO 14001

ISO 50001 (Energy Management)

This international norm supports companies and organizations in the development of a systematic energy management system aimed at improving energy efficiency, reducing energy usage, and promoting adherence to legal requirements. At HPC centers like HLRS, which require large amounts of power for the operation and cooling of their computers, this means committing to implement measures that will minimize carbon emissions and consumption of nonrenewable resources. At HLRS this has involved setting targets for energy usage, tracking actual energy consumption, and making infrastructure improvements to optimize energy efficiency. Learn more about ISO 50001.
