A novel approach to the problem of geographic allocation of environmental impact in Life Cycle Assessment and Material Flow Analysis

摘要: Abstract Life Cycle Assessment and Material Flow Analysis, in spite of their invaluable contribution to the investigation environmental performance human-dominated processes, still fall short properly addressing issue geographic distribution potential impacts, which often has wide-reaching as well political implications. An innovative allocation method based on matrix algebra is introduced here, order allow split calculated impact indicators into fractions thereof are geographically attributed different world regions. This done basis of: (i) where analyzed process takes place (ii) directly indirectly required fossil nuclear fuels sourced from (including those for electricity production). The been successfully tested primary aluminium production, a first case study.
