Digital Rebound: Why Digitalisation Will Not Redeem Us Our Environmental Sins

This paper is trying to make the case for a faithful consideration of the rebound effects of digitalszation. 

This paper addresses several aspects for the assessment of single ICT services: the goal and scope definition (analyzing differences between ICT substitution and optimization, the time perspective of the assessment, the challenge of a hypothetical baseline for the situation without the ICT solution, and the differences between modelling and case studies) as well as the often-ignored influence of rebound effects and the difficult extrapolation from case studies to larger populations.

Building on the assessment of single services, this article identifies and addresses shortcomings of existing methodologies and industry practices with regard to multiple services assessment.

How viable are Energy Savings in Smart Homes?: A Call to Embrace Rebound Effects in Sustainable HCI

In this paper, we ask: to what extent have rebound effects and their underlying mechanisms been considered in computing, HCI and smart home research? To answer this, we conducted a literature mapping drawing on four scientific databases and a SIGCHI corpus. 

Given the critical need to develop and employ robust and consistent methodologies to assess, review, and evaluate the energy and climate effects of digitalization, over 70 leading researchers, practitioners, and policy makers participated in a two-day expert workshop in May 2021. This paper provides essential background on the need for the workshop. It highlights key outcomes, including actionable insights that were put forward by the expert participants.

Given growing concerns about this energy consumption, the current paper analyses the different factors that affect the energy consumption of one blockchain, and identifies the best levers for its mitigation.

The report performs an in-depth analysis of estimates of the energy intensity (EI) and the overall energy (E) consumption of the Internet.

Rebound effects of digitalisation have been ignored until recently, but they have been increasingly studied lately. One particular mechanism of digital rebound, however, has been largely disregarded so far: the digitalisation-induced lowered skill requirements needed to perform a specific activity. In this paper, we propose the term skill rebound to denote this mechanism

This paper propose a novel method which considers the proximity patterns of WiFi and Bluetooth (BT) devices in the environment, which are expected to be quite specific to the different transportation modes.

Estimating the Savings Potential of Occupancy-based Heating Strategies

While substantial work has been done on occupancy detection, previous work does not address a combination with heating simulation in order to provide an easily applicable method to estimate this savings potential. In this paper we present such a combination of an occupancy detection algorithm based on smart electricity meter data and a building heating simulation.

The Energy Intensity of the Internet: Edge and Core Networks

A bottom-up model for the energy intensity of the Internet that draws from the current state of knowledge in the field and is specifically directed towards assessments of digital services.

Effects of Internet-based Multiple-site Conferences on Greenhouse Gas Emissions

This article presents the results of a field experiment for one particular domain in which ICT can be substituted for more carbon-intensive technologies: using advanced videoconferencing technology to reduce intercontinental conference travel and thus travel-related GHG emissions.
