HTW Berlin’s Campus Stories features the GRÜNS project (“Gemeinsame Richtlinien zur Überprüfung der ökologischen Nachhaltigkeit von Software”), led by Prof. Dr. Verena Majuntke and funded by the Federal Ministry for Economic Affairs and Energy. Together with the Gesellschaft für Informatik (GI), we are a partner in the project, which works closely with DIN to develop a scientifically grounded standard for sustainable software — first as a DIN norm and later as an ISO standard. The goal is a comparable sustainability score covering energy as well as other resources, hardware and emissions.

We were invited by Prof. Dr. Marie Bergmann to give a guest lecture at Hochschule Bonn-Rhein-Sieg (H-BRS) on the topic of Green Coding — presenting a systematic framework for understanding software emissions, measurement methods, and practical tools for more energy-efficient software development.

ecoCompute 2025 was a blast! We have released the re-cap video to give you some impressions from the conference for everyone who could not attend.

For everyone else: Thank you all for being part of this wonderful iteration of ecoCompute ❤️

You can find the slides on the conference website schedule

The final program for ecoCompute 2025, the biggest green tech conference on sustainability in hardware and software, is now online.

Tickets are available until 12.11.2025. Secure yours today to attend inspiring talks, hands-on workshops, and networking sessions with top speakers, driving digital sustainability forward.

For ecoCompute 2025 we are bringing a strong partner on board: Bits & Bäume.

The german digital sustainability comprised of tech people (Bits) and classical sustainability / ecology folks (Bäume) is running it’s own track (The Community Track) and a welcoming connect space.

We are proud to be part of the Sustainable AI Futures project, a research project led by Bath Spa University, supported by the AHRC BRAID programme. The project explores the intersection of AI and environmental sustainability, including the social and political impacts of AI environmental governance tools.

We are excited to announce that we are part of the CASO project, which is funded by the German Federal Environmental Foundation (DBU).

The CASO project aims to make software development more energy and CO₂ efficient. It integrates technologies directly into the development process to give developers transparency about their software’s energy consumption and CO₂ emissions. By combining measurements, data analysis, and AI-supported recommendations, developers can make informed decisions to create more sustainable software. The project intends to highlight optimization possibilities for configuration, algorithms, and operating system settings.

Our Green Metrics Tool was awarded the Blue Angel for software at a ceremony at the Federal Ministry for the Environment - making us the first open source energy and CO2 measurement tool to be awarded the eco-label.

Our joint paper Development and evaluation of a reference measurement model for assessing the resource and energy efficiency of software products and components—Green Software Measurement Model (GSMM) from 12 groups of researchers and practitioners has been selected for the Spring 2025 Editor’s Choice award!

The environmental impact of software and hardware systems has become a pressing concern. While mainstream operating systems like macOS and Windows provide proprietary tools to analyze energy usage, Linux—the cornerstone of open-source computing—lacks comparable capabilities. To address this gap, we present PowerLetrics, an open-source framework enabling detailed, per-process energy footprint analysis on Linux systems.

Our study in collaboration with Prof. Dr. Verena Majuntke from HTW Berlin and dena (German Energy Agency) has been published!

The content is the analysis and recommendations for action for politics, companies, research and civil society on how green coding can contribute to sustainable digitalization and reduced electricity consumption.

Our Green Metrics Tool has been awarded the Blue Angel for resource and energy efficient software! Details: Blog article / Product page on Blauer-Engel.de

Unser Pitch bei den WSA Awards für Green Coding Solutions und das Green Metrics Tool.

Wir sind stolz und glücklich 🤩, bekannt zu geben, dass die Green Coding Solutions GmbH einer der diesjährigen Gewinner des Green Screen Catalyst Fund ist! Als eines von 15 Unternehmen, die aus über 350 Bewerbungen ausgewählt wurden!

Damit wird die Entwicklung eines unserer Tools zur Evaluierung des Energieverbrauchs im Linux-Kernel - und damit die Einsicht und Quantifizierung der Energiekosten von Software auf Prozessebene - ermöglicht und weiter unterstützt.

Vielen Dank an die Green Screen Coalition 🌱 (Ariadne, Ford Foundation, Internet Society Foundation, Mozilla Foundation, Green Web Foundation, Critical Infrastructure Lab und die Mercator Foundation) für die Finanzierung dieses bahnbrechenden Fonds 🙏.

We have been tasked by the dena (Deutsche Energie Agentur) to make a hopefully groundbreaking study on Green Coding als Standard in der Softwareentwicklung für eine stromsparende Gestaltung der Digitalisierung.

Our Green Metrics Tool has been awarded the WSA Global Awards in the category Environment & Green Energy. 🙏😍

Our Press Release for the EcoCompute 2024 conference journalists to share and publicize.

The final program for Eco Compute, 2024, the first tech conference on sustainability in hardware and software, is online.

Ticket sales are open until 24.04.2024. Get your ticket now to join our sensational speakers at talks, workshops and networking to bring the topic of digital sustainability to the forefront.

We are invited to give a guest lecture at the Mannheim Business School about Green Coding.

The Indian Institute of Management is visiting Mannheim Business School in January for a study trip to hear some lectures about sustainability and sustainabile management.

We are delighted to have been invited to give two talks in this period:

• Sustainability in the digital world: European perspective
• Understanding software carbon emissions and saving potentials for management

The first tech conference on sustainability in hardware and software. EcoCompute brings together software developers, hardware designers and data center professionals to create a sustainable digital future. The Call for Speakers opens on 01.12.2023 until 31.01.2024. We are looking forward to exciting presentation submissions!

Wir beteiligen uns dieses Jahr als Workshop-Organisator am Green Coding Summit der SDIA und bieten Ihnen einen 5-stündigen Workshop an, in dem wir viele Tools rund um grüne Softwareentwicklung und Techniken zur Messung und Ökologisierung Ihrer Projekte vorstellen.
