“…As the project progressed, two reports were released that addressed the life-cycle impacts of CRTs and LCDs to a limited extent; however, they were separate reports and did not quantitatively evaluate both CRTs and LCDs together [5,6]. Since the completion of the final Computer Display Project report (December 2001), an LCA study of color computer monitors was published; however, this study only addressed CRTs [7].…”

“…One PC system used 1,000 kW h PEU for manufacturing and 880 kW h electricity during its 3-year lifetime, i.e., a considerate dominance of the use phase. Kim et al (2001) conducted an LCA for a colour computer monitor. They produced useful figures on material contents.…”

Background, aim, and scope During the last decades, the electronics industry has undergone tremendous changes due to intense research leading to advanced technology development. Multiple life cycle assessment (LCA) studies have been performed on the environmental implications of consumer electronics. The aim of this review is to assess the consistency between different LCA studies for desktop computers, laptop computers, mobile phones and televisions (TVs). Materials and methods A literature study was conducted covering some key LCA contributions to the consumer electronics field. The focus is primarily on global warming potential during 100 years (GWP100) efficiency in different life cycle phases and secondarily on primary energy usage/ electricity usages which are normalised per year to find inconsistencies. Results The life cycle impact assessment GWP100 results for consumer electronics over the years suggest that most studies are of comparable quality; however, some studies are neither coherent nor transparent. Published LCAs for mobile phone and TV sets are consistent, whereas for laptop and desktop computers, the studies occasionally give conflicting messages. Discussion The inconsistencies appear to be rooted in subjective choices and different system boundaries and lifetime, rather than lack of standardisation. If included, the

“…(Bush et al 2009)). Similarly, many life cycle assessments of products (for example (Kim et al 2001;Moberg et al 2010)) use industrial data based on direct measurements on real products. For modelling and prospective purposes during design, electronic component characteristics are used to calculate power (Li et al 2008;Violette et al 2000).…”

“…A third mode appeared in recent years: the Stand-by mode, where the product seems to be off (not operating) but is still performing internal tasks not visible for the user. Kim et al (2001) defined three modes for computer monitors: 4 hours per day in the on mode, 4h per day in the energy saving mode (similar to the stand-by mode), the rest of the time in the off mode, each of them with its own associated power consumption (P on ; P standby ; P off ). Moberg et al (2010) used three modes for the evaluation of an e-paper reader over 1 year of use: 30 minutes per day reading newspapers (on mode), 30 minutes per day for other usage (setting, downloading papers, reading e-books…-stand-by mode) and the rest of the time in the off mode.…”
