The HLRS Environmental Statement is issued annually as a requirement of the center's certification under the Eco-Management and Audit Scheme (EMAS). The Environmental Statement contains the latest policies at HLRS and the Institute for High-Performance Computing (IHR) related to sustainability and environmental protection, and documents efforts that HLRS and IHR have taken to continually improve their environmental performance and address climate change.
Each Environmental Statement is based on the latest year for which complete data are available.
This HLRS Sustainability Report documented HLRS's activities in the area of sustainability and environmental management for the first time, and laid the foundations for the development of the center's environmental management system, which was formally certified under the ISO 14001 and ISO 50001 standards in late 2019, and the Eco-Management and Audit Scheme (EMAS) in early 2020. As a requirement of EMAS, we now publish an environmental statement annually. This is enhanced by further sustainability aspects.
This guidebook, "Sustainability in Computing Centers" was developed as part of the project "Sustainability in HPC Centers II." The primary focus of this project was to implement a sustainability concept at the High-Performance Computing Center Stuttgart (HLRS). The result was the development of an environmental management system that was certified in compliance with EMAS, the Eco-Management and Audit Scheme, and the DIN EN ISO 50001 standard for energy management in organizations.
By publishing this guidebook we would like to make the experience we gathered on the road to improving our sustainability accessible to other computing centers. The practical examples contained in this guidebook arose in the context of a public institution that specializes in high-performance computing. Nevertheless, much of what we learned will also be of interest to computing centers in the commercial sector as well.
We hope that you will find many useful tips in this guide that will help you in implementing your own plans for making supercomputing more sustainable.
