Because the operation of high-performance computing centers requires sizable amounts of energy and other resources, HLRS has committed itself to taking practical measures whenever possible to reduce its CO2 footprint, prevent pollution, and limit other negative effects on the environment.

HLRS was the first supercomputing center to be certified under the Eco-Management and Audit Scheme (EMAS), the most demanding system for environmental management in organizations worldwide. It is also officially certified under the German "Blue Angel" seal and international standards for environmental management (ISO 14001) and energy management (ISO 50001).

These achievements have involved the systematic development of a comprehensive set of guidelines for environmental and energy management at HLRS, covering all aspects of the center's operations. All employees at HLRS are involved in ensuring that these guidelines are put into practice and in the continual improvement of HLRS's environmental sustainability over time.

HLRS also plays an essential role in supporting research focused on improving sustainability in other sectors of society. Simulation using supercomputers at HLRS is essential, for example, in research to improve fuel combustion efficiency, to design more energy-efficient wind turbines, cars, and airplanes, and to create more precise and reliable models of weather and climate change. New insights delivered using simulation are thus supporting the development of technologies and products that improve sustainability more broadly.

HLRS is committed to sharing its knowledge about sustainability, organizing events that promote the professional exchange of information about sustainability best practices in supercomputing, and promoting the center's achievements to the wider public.
