The greenhouse gas (GHG) reduction potential of ICT: A critical review of telecommunication companies’ GHG enablement assessments
For about a decade, telecommunication network operators (TNOs) have explored the potential greenhouse gas (GHG) reductions their customers can achieve by using TNO services (e.g., by substituting physical travel with video conferencing), the so‐called GHG enablement . Some TNOs also calculate a GHG enablement factor , which is the ratio between the GHG enablement and their own GHG footprint. Since GHG enablements usually exceed the footprint, they create the narrative that TNOs contribute to GHG reductions across society. In this paper, we systematically analyze TNO GHG enablement claims and the underlying methodological approaches. We find several methodological shortcomings and inconsistencies, such as different sets of TNO services considered, inconsistent system boundaries, potential double counting of GHG reductions, and a disregard for rebound effects. Most importantly, TNO assessments focus exclusively on those services likely to yield GHG reductions, neglecting possible GHG‐increasing services. We conclude that current GHG enablement (factors) do not accurately and comprehensively represent TNOs’ overall GHG impacts and create a flawed picture. To provide a reliable decision basis to stakeholders such as TNOs themselves, customers, investors, and policymakers, we provide eight recommendations on how to substantially improve the methodological basis.

Ausgebummelt – Wege des Handels aus der Spass- und Sinnkrise
Repräsentative Studie zum Schweizer Handel Nach Lieferkettenengpässen, steigenden Rohstoffpreisen und Fachkräftemangel stellt nun ein weiterer Faktor den Handel vor eine grosse Herausforderung: Zeit. Sie wird bei Konsumentscheidungen zur kritischen Ressource. 30 % aller Schweizerinnen und Schweizer im erwerbsfähigen Alter stehen häufig oder fast immer unter Zeitstress. Die wertvolle Zeit wollen KonsumentInnen immer weniger mit Shoppen verbringen. Die Ergebnisse der neuen Handelsstudie des GDI «Ausgebummelt – Wege des Handels aus der Spass- und Sinnkrise» deuten darauf hin, dass sich die Einstellung zum Einkaufen gewandelt hat. Es wird nicht mehr als angenehme Freizeitbeschäftigung, sondern als «mühsame Tätigkeit» wahrgenommen. Vier Shopper Typen Die unterschiedlichen Einstellungen zum Einkaufen werden in der Studie mit vier Shopper-Typen dargestellt: ziellose BummlerInnen, strikte BedarfskäuferInnen, aufgeschlossene OptimiererInnen und effiziente IdentitätskäuferInnen. Vier Wege für den Handel aus der Spass- und Sinnkrise Damit Einkaufen für KundInnen wieder attraktiver wird, muss der Handel sich gemäss den GDI-Forschern an vier Ps halten: Er muss schneller (Promptness), näher (Proximity), schöner (Pleasure) und sinnvoller (Purpose) werden. Der Handel muss den Menschen Zeit zurückgeben und zum Zeitgestalter seiner KundInnen werden.
