dc.description.abstractThe emissions of the ICT sector are increasing as well as the number of mobile internet-enabled devices (MIEDs, smartphones, tablets and laptop). On the level of consumers, the devices themselves account for the majority of impacts caused the consumption of ICT services due to the MIED production requiring resources and energy as well as emissions that arise in their supply chain. The environmental hotspots for the impacts of the devices are the integrated circuits used for memory and central processing units (CPU). However, the components with the largest influence on the lifetime are displays as well as batteries. Therefore, extending the service life of MIEDs by replacing batteries and displays can significantly reduce the environmental impacts associated with MIEDs. In order to holistically assess the environmental impact of measures for service lifetime extension, rebound mechanisms and indirect effects must be taken into account. These effects can be categorised in three categories: (1) induction effects, (2) substitution effects and (3) re-spending effects. We analysed the environmental impacts of these three different categories of indirect effects and found out that repairing MIEDs leads to net savings in environmental impacts, even if re-spending is considered. For all devices the net savings are the highest for mineral resources and less pronounced for particulate matter and GHG emissions. Total environmental impacts show significant net savings for all device types. However, the rebound effects caused by re-spending and imperfect substitution have a high range and inherent uncertainty due to the underlying assumptions and will have to be further analysed with sensitivity and uncertainty analysis.de_CH
