Life Cycle Assessment for Mobile Products Background Samsung has developed strong technical experience in assessing the life cycle environmental impacts of its smart phones. The most recent life cycle assessment (LCA) has been for the Samsung Galaxy S6; Note5; Tab E model. The assessment considers potential environmental impacts across the whole life cycle including; pre-manufacturing; product manufacturing; distribution; product use; and disposal phase. To ensure technical quality; the analysis methodology has been completed according to international standard ISO 14040 series. Samsung has used Simapro7 software and a dedicated LCA S/W database to measure environmental impacts using a wide range of data categories including; Product bill of material (BOM), parts and components logistics, energy consumption in product use and end-of-life scenario data in order to attain the highest level of accuracy. The outcome of the LCA confirmed and quantified 12 potential environment impact categories including; global warming; abiotic depletion; ocean acidification; eutrophication; and ozone layer depletion; where each impact category has been assessed for each life cycle stage. These LCA results will continue to be considered during product development phase as we aspire to improve the environmental specifications of our products. Calculation basis Standard ISO 14040:2006 and 14044:2006 Database Ecoinvent 2.2 Method for impact assessment LCA software Life cycle impact assessment classification and characterization factors according to CML 2001 as provided in the SimaPro 7.1.5 LCA tool SimaPro 7.1.5 System boundary of LCA Premanufacturing Parts and materials constituting the products and its transportation (from supplier to Samsung factory) Manufacturing Product assembly by Samsung Electronics (Data collection period : April ~ May, 2015) Distribution Usage Disposal From China or Vietnam to United States 2 years use Waste treatment of parts and material Critical review for Galaxy S6 LCA study was done by an expert from Korean Society for Life Cycle Assessment.
