Abstract

Life cycle assessment (LCA) has been accepted widely as an effective tool for the evaluation of environmental loads accompanying products or services, but the method of practical application needs to be further improved. EMLCA, which is a matrix-based LCA software, is developed on the Excel spreadsheet. This LCA software has many functions such as environmental load calculation, environmental impact assessment, sensitivity analysis and uncertainty analysis. On the other hand, problems in data acquisition appear in almost every LCA case study. In order to support the LCA practice in Japan, an LCA database has been developed by JLCA. A simple introduction to EMLCA and the JLCA database is presented and they are used to carry out an LCA case study of a copier. The environmental loads corresponding to one copier in its life cycle are calculated, and the environmental impact caused by the loads is assessed. Sensitivity analysis and uncertainty analysis are also carried out, and methods of improving the environmental aspects are discussed.

使用基于矩阵的LCA软件和JLCA数据库对复印机进行LCA案例研究

生命周期评价(LCA)作为产品或服务伴随环境负荷评价的有效工具已被广泛接受，但实际应用的方法有待进一步完善。EMLCA是一种基于矩阵的LCA软件，是在Excel电子表格上开发的。本软件具有环境负荷计算、环境影响评价、敏感性分析、不确定性分析等功能。另一方面，数据采集方面的问题几乎出现在每一个LCA案例研究中。为了支持日本的LCA实践，JLCA开发了LCA数据库。简要介绍了EMLCA和JLCA数据库，并将它们用于复印机的LCA案例研究。计算了一台复印机在其生命周期中所对应的环境负荷，并评估了这些负荷对环境的影响。并进行了敏感性分析和不确定性分析，探讨了改善环境因素的方法。
