“…Polymers form a major share in electronics in general and in the case of mobile phones, this is higher than that of any other material. It is estimated that 30-40% of a mobile phone is built up by polymers alone (Wager et al, 2015). The polymers used in mobile phones mostly come under the category of engineering plastics, which may still have good properties at the end of the lifecycle of mobile phone (Clean Up Mobile Phones, 2007; Stevens and Goosey, 2008).…”

“…These include for example impacts related to human and ecotoxicity, however, the assessments of these impact categories often contain a lot of uncertainty [53]. Focusing solely on GHG emissions and energy use may generate misleading results [54] regarding both potential impacts and benefits.…”

Mobile data consumption in Finland is among the highest in the world. The increase in mobile data usage has been rapid and continual future growth is foreseen. Simultaneously, consumer behaviour is changing. While new end-user devices are more and more energy-efficient and energy consumption per transferred gigabyte has significantly decreased, people spend more time and consume more data via their mobile devices than ever before. Does the increased usage outweigh the energy savings that have been achieved? What options are available for tackling increasing energy demand? And should consumers have a role to play in this discussion? This paper examines the current and future trends that results from the energy consumption of mobile data transfer and mobile networks in Finland. The findings presented in this paper are based on a top-down energy intensity estimate and publicly available data, which was employed to construct an illustrative trend (kWh/gigabyte) for the energy consumption of transmitted mobile data for the years 2010–2017. In addition, energy consumption related to mobile data transfer is discussed from a life cycle perspective, considering both direct and indirect energy use. Finally, the challenges in conducting such assessments are examined.

“…Green in ICT does not only encompasses the direct energy consumption (and CO2 emissions) of the ICT sector [15,16], but also considers other aspects such as miniaturization, integration, hardware churn/obsolescence [17,18], resource use [19,20] as well as the end-of-life treatment (e.g. formal or informal recycling or disposal of e-waste, e.g.…”

Abstract-Technological developments in screen technologies pitches the thinner, brighter and energy-stingy OLED screen as a possible replacement for today's television, computer and smartphone LCD screens. An OLED screen does not consume any energy at all when it displays the color black, but the potentially large energy savings can unfortunately evaporate and instead turn to losses when white is displayed. There is thus a mismatch between on the one hand the energy profiles of OLED screens and on the other hand user habits and current webpage design practices. This example thus raises important questions about system boundaries and about how to evaluate sustainable (or "sustainable") technologies.We conducted a pilot study of user acceptance of alternative, OLED-adapted color schemes for webpages. We briefly discuss the results of the study, but primarily use it as a starting point for discussing the underlying questions of where, or indeed even if it makes sense to work towards realising the OLED screens' potential for energy savings. Moving from LED to OLED screens is not only a matter of choosing between competing screen technologies, but would rather have implications for hardware and software design as well as for the practices of web designers, end users and content providers.
