生命周期评价(LCA)作为一种评价产品或服务环境负荷的有效工具已被广泛接受，但其实际应用方法还有待进一步完善。EMLCA是一个基于矩阵的生命周期分析软件，是在Excel电子表格上开发的。该软件具有环境负荷计算、环境影响评价、敏感性分析和不确定性分析等功能。另一方面，数据获取方面的问题几乎出现在每个生命周期评价案例研究中。为了支持日本的生命周期评价实践，日本生命周期评价机构开发了生命周期评价数据库。简要介绍了EMLCA和JLCA数据库，并用它们进行了复印机的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，并对负荷对环境的影响进行了评估。并进行了敏感性分析和不确定度分析，探讨了改善环境方面的方法。
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.
