Digital Sufficiency: Conceptual Considerations for ICTs on a Finite Planet.

Information and Communication Technologies hold significant potential to increase resource and energy efficiencies and contribute to a circular economy. This article by Tilman Santarius and 9 others international authors in the Annals of Telecommunications for the first time develops the concept of Digital Sufficiency, which constitutes a basis to understand how ICT can become part of a deep sustainability transformation. The conceptual work builds on five years of multidisciplinary empirical and theoretical work on digitalization and sustainability. The article manifests four dimensions of Digital sufficiency – hardware sufficiency, software sufficiency, user sufficiency, and economic sufficiency – and presents a set of strategies and policy proposals for each.
