What makes FOSS sustainable?
Free & Open Source Software (FOSS) guarantees transparency and user autonomy, by design. These are not features, but inherent qualities to open development and software licensing. As a result, software and hardware are no longer dependent on vendors for support.
FOSS can be studied and improved independently, including in its energy consumption. Premature hardware obsolescence is a thing of the past. FOSS runs on devices that are decades old. Keep your computer in use to the end of the hardware operating life, not the software.

About KDE and KDE Eco
KDE is a world-wide community of software engineers, artists, writers, translators, and creators who are committed to Free Software development. We are a cooperative enterprise: we work together to achieve the common goal of building the world's finest Free & Open Source Software. Everyone is welcome to join and contribute to KDE, including you.
Supported by the KDE community since 2021, KDE Eco has the ongoing mission of the development and adoption of sustainable Free & Open Source Software worldwide. As the ecological impact of digitization grows more relevant, we continue to raise awareness about the role of software design in reducing environmental harm. We are proudly a part of a growing number of communities and organizations working to have a positive ecological impact, today.
