Switzerland has taken a pioneering step in adopting open-source software (OSS) for its government operations with the enactment of the “Federal Law on the Use of Electronic Means for the Fulfillment of Government Tasks” (EMBAG). This law mandates the release of government-developed software under open-source licenses, promoting transparency, reducing vendor lock-in, and potentially lowering IT costs. Moreover, this shift towards OSS aligns with ecological sustainability, allowing for energy-efficient software customization and reducing the environmental impact of digital infrastructure. Switzerland’s move may serve as a model for other nations, highlighting the intersection of technological innovation and environmental responsibility.
