Environmental Impact Assessment Logic for ICT systems named SI-LCA and its Case Example

have studied about assessment for ICT environmental impact and finally developed an assessment logic named SI-LCA1 (system integration LCA) that quantitatively evaluates whole life cycle environmental impact with CO2 emission for ICT solutions. SI-LCA is not only compliant with "guideline for information and communication technology (ICT) Eco-Efficiency Evaluation" instituted by The Japan Forum on eco-efficiency in 2006 but also one of the most important basic logics for the guideline. In this paper, we show a case example of SI-LCA assessment and then show evaluation of ICT eco-efficiency and factor.
