Student thesis: Master typesMaster in Computer Science Professional focus in Software engineering


This thesis analyzes a very large number of Life Cycle Assessment (LCA), in
terms of carbon footprint, of Smartphones and Tablet computers. The overview of these studies shows how LCA results vary over time. The thesis clearly identifies the production phase and the use phase of the devices as major contributors to the environmental impact.
The production phase is analyzed in more depth. The focus is on integrated circuits, printed circuit boards and displays. The lack of accurate data and evaluation methodology is highlighted for the first two components.
The use phase is also investigated to understand the main parameters that drive
the use phase result. A normalization of the use phase is applied in order to facilitate the comparison between the devices.
