KDE's Sustainable Software Goal

Software has a direct affect on energy and resource consumption. Since 2022, KDE has the goal of providing software which does this in a way that reduces software's environmental impact for us and future generations.

FOSS Energy Efficiency Project (FEEP)

Wie lässt sich der Energieverbrauch von Software messen? Und macht das einen Unterschied? Wir arbeiten daran, Freie Software nachhaltiger zu machen.

KDE Eco - Freie Software energieeffizient entwickeln

Software has a direct affect on energy and resource consumption. KDE has the goal of providing software which does this in a way that reduces software's environmental impact.

Let’s make energy efficient software and digital sustainability part of our community. We can live up to our responsibility for this and future generations!

KDE Eco Handbook

The handbook "Applying The Blue Angel Criteria To Free Software" gives an overview of the environmental harm driven by software and how the Blue Angel ecolabel — the official environmental label of the German government — provides a benchmark for sustainable software design. Learn how Free Software's values of transparency and user autonomy foster sustainability, as well as how to set up a dedicated lab to measure your software's energy consumption!   Mehr dazu

What is Sustainable Software, After All?

"Sustainable Software" is a strategic goal for KDE, focusing on minimizing resource consumption and strengthening user autonomy. The aim is to create software that uses fewer natural resources, reduces energy consumption, and promotes user choice and privacy. Mehr dazu

FEEP is developing tools to improve energy efficiency in Free & Open Source Software development. Design and implementation of software has a significant impact on the energy consumption of the systems it is part of. With the right tools, it is possible to quantify and drive down energy consumption. This increased efficiency contributes to a more sustainable use of energy as one of the shared resources of our planet.

Blauer Engel For FOSS (BE4FOSS)

In 2020, the German Environment Agency (German: Umweltbundesamt) released the award criteria for eco-certifying desktop software with the Blue Angel ecolabel (German: Blauer Engel). From 2021-2022, the BE4FOSS project under KDE Eco worked to advance eco-certification for resource and energy-efficient software in FOSS communities. Obtaining the Blue Angel ecolabel occurs in 3 steps: (1) Measure, (2) Analyze, and (3) Certify.

Benefits of obtaining the Blue Angel ecolabel include:

  • Recognition of reaching high standards for environmentally-friendly software design,
  • Differentiating free software from the alternatives,
  • Increasing the appeal of adoption for consumers, and
  • Promoting transparency in the ecological footprint of software.
