Shaping digital transformation for a sustainable society -- Contributions from Bits & Bäume

This companion book to the "Bits & B\"aume" conference 2022 compiles the insights, work, research and opinions of more than 65 authors with a "Bits & B\"aume" background, including practitioners, researchers and activists. The articles demonstrate the progress made in merging "Bits" and "B\"aume" (Trees) topics since our first publication in 2019 by addressing different sub-areas of the intersections between digitalisation and sustainability. Encompassing a wide range of topics, the articles delve into pressing challenges such as the resource consumption, power implications and democratic governance of digital infrastructures, AI, blockchains, mobile apps, and other software applications, as well as the need to address the unsustainable practices and paradigms of e.g., the platform economy. Offering not only transparency but also solutions, the journal presents practical approaches and concepts related to the necessary transformation, such as the Computer Science for Future programme. It also contains articles commenting on current political developments, such as the EU legislation on sustainability and freedom-related aspects of ICT devices. Further articles highlight the power of and need for an active civil society, aiming to inspire activism. This journal caters for everyone: Are you just getting into the topics around Bits & B\"aume?
