ew social, economic and ecological problems. Important first steps have been made to discuss the role of technology and the digital world. Yet we have to continue to actively shape the path of a truly sustainable digitalization. As a framework, in this paper we propose one of the most comprehensive sustainability concepts ever agreed on by the world: The 2030 Agenda with its Sustainable Development Goals (SDGs)." (Page 1)

ft müssen endlich gemeinsam diskutiert werden. Die ‹Bits & Bäume› hat vielfältige Akteure zusammengebracht, vor allem aus der Tech-Szene und der Nachhaltigkeitsbewegung, aber auch aus Wissenschaft, Wirtschaft und Politik. Die Konferenz hat gezeigt: Wir brauchen dringend neue Foren, um uns mit Digitalisierung auseinanderzusetzen. Verschiedene Akteure müssen gleichberechtigt und demokratisch daran teilhaben. Denn wie die Digitalisierung politisch gestaltet wird, darf nicht vordergründig von wirtschaftlichen Erwägungen abhängen. Mit diesem Buch möchten wir zentrale Inhalte der‹Bits & Bäume› für diese gesellschaftliche Debatte festhalten." (Editorial, Seite 2)

al growth of from 9% to 10% according to the different hypotheses. This hyper-growth, occurring in spite of regular advances made up to now in the energy efficiency of digital devices and systems, is resulting in: The appropriation of a progressively disproportionate share of available electricity, increasing tension on the buildup of non-carbon production sources; The increase by half in 5 years of digital technology in GHG emissions (2.5% to 3.7% between 2013 and 2018) and a twofold increase of this ratio from now to 2025 (if data traffic continues to grow by 30% a year); Increasing demand for rare and critical metals of which many are essential for low carbon energy technologies, hence a risk of tension regarding supplies, exacerbated by the almost monopolistic position of China with respect to most of these metals [.] So that digital transition can contribute to reducing the global energy consumption of a system, it is vital to change our consumption patterns and integrating digital technology in our projects, by applying the following recommendations: 1. Adopt digital sobriety as a principle of action; 2. Inform and spread awareness; 3. Mobilize the lever of public purchasing; 4. Allow companies and organizations to manage the environmental dimension of their digital transition; 5. Carry out a carbon balance of digital projects to facilitate their prioritization; 6. Improve consideration of the systemic dimensions of digital technology; 7. Work at the European scale and with international organizations." (Conclusions, page 60-63)

lt die bisher größte Herausforderung dar, der sich der WBGU seit seiner Gründung im Rio-Jahr 1992 gestellt hat: in intellektueller, in politischer und in ethischer Hinsicht. Denn der WBGU dehnt den Analyseraum über seinen Kernkompetenzbereich hinaus aus, weil das künftige Schicksal der planetarischen Umwelt massiv vom Fortgang der digitalen Revolution abhängen wird. Er mischt sich in einen gesellschaftlichen Diskurs ein, der immer hektischer geführt wird, weil es um die globale Innovationsführerschaft im 21. Jahrhundert geht. Und er versucht, Antworten auf Kernfragen zu finden – Fragen nach der mittelfristigen Zukunft, ja sogar nach dem schieren Fortbestand des Anthropos auf der Erde. Nur wenn es gelingt, die digitalen Umbrüche in Richtung Nachhaltigkeit auszurichten, kann die Nachhaltigkeitstransformation gelingen. Digitalisierung droht ansonsten als Brandbeschleuniger von Wachstumsmustern zu wirken, die die planetarischen Leitplanken durchbrechen. Nachhaltigkeitspioniere müssen die Chancen von Digitalisierung nutzen und zugleich deren Risiken einhegen." (Zusammenfassung, Seite 1)

rity, save power, and maintain and dispose of your old hardware. Suggestions and advice for policy makers are also included, along with some practical tips for internet service providers. Written by IT expert and environmentalist Paul Mobbs, the purpose of the guide is to encourage ICT-for-development (ICTD) practitioners to begin using technology in an environmentally sound way. But its usefulness extends beyond this to everyday consumers of technology, whether in the home or office environment. We can all play our part, and the practice of sustainable computing will go a long way in helping to tackle the environmental crisis facing our planet." (Back cover)

"The main structure of the document consists of four parts.

Based on the above, the a

nalysis will suggest some of the key gaps and issues that need to be considered as research on ICTs, climate change and development continues to evolve. The second section deepens the analysis by identifying the key components of the debate, namely the role of ICTs in mitigation, monitoring, adaptation and strategies, while building up the basis of a conceptual model on ICTs, Climate Change and Development (Figure 2). This model will provide the reader with an overview of the main issues and trends that lie at the intersection of these three fields, mapping the links between its main components and serving as a tool to identify challenges and research gaps that need to be further explored. Having identified the main issues on ICTs and climate change from a global perspective, the third part of the document will present some of the emerging examples of ICT use in climate change mitigation, monitoring, adaptation and strategies in Africa, Asia and Latin America. This section will allow the reader to contextualize the debate from a developing country perspective, while relating the ideas reflected in the ICTs, Climate Change and Development model to concrete actions in the field. The study concludes by presenting key issues for future research, based on the gaps and developing country priorities identified throughout the analysis. It has three Annexes: one providing a timeline of key literature resources; one offering an extended bibliography of that literature; and a glossary of key terms." (Page 4)

"Given the budget, good quality new PCs are likely to be the most stable, and in many instances will be the preferred technology choice.

urchase prices can account for 63-85% of the ownership costs that make TCO different between new and refurbished PCs. In contrast, a key TCO inhibitor for refurbished PCs is their failure rate and associated ongoing costs, accounting for 64-75% of the comparative TCO costs. A network of good quality refurbished PCs (imported brands such as Hewlett Packard, Dell and IBM) offers a window period of stability, making them a viable technology choice under certain conditions. They are likely to have the lowest TCO over five years. While the hardware replacement costs over that period could be the equivalent of the purchase price of the PCs, most of these costs are likely to occur in the final years of ownership. The high frequency of failures, together with the high ongoing costs for lower quality refurbished PCs (some 75% of the comparative totals), suggests that they should not be considered a viable technology option. In the case of lower quality refurbished PCs, hardware replacement costs alone can be more than 140% the purchase price of the PCs. A high level of failure can be expected throughout the five years of ownership." (Executive summary, p.4)
