摘要

使用Sitewise^TM和SEFA对我国北方某城市污染场地修复活动产生的环境足迹进行对比分析，比较其方法原理、指标体系、适用范围和改进建议.结果表明，两款工具在该案例中对温室气体排放量、能源消耗量的模拟一致性相对较好，但对NO_x、SO_x、PM等大气污染物的评估结果存在一定差异，主要由于部分修复环节内置数据库排放因子差异较大.两款工具均能识别出造成环境影响的关键修复环节，也可以同时对不同修复方案进行对比分析，但是对经济、社会指标的评估不充分，缺乏敏感性分析等功能，指标体系和内置数据库与我国实际情况有差异.建议根据我国能耗水平和污染物排放特点，研发适合我国国情的定量测算修复活动环境足迹的工具，为修复活动减污降碳提供科学依据.

Abstract

In this study, the Sitewise^TM and SEFA tools were used to analyze environmental footprint of remediation activities of a contaminated site in a northern China city, and compared the methodology, input and output indicators, scope of application and suggestions for further development. The results showed relatively high consistency in simulation of greenhouse gas emissions and energy consumption, but there were still certain differences in the evaluation results of air pollutants including NO_x, SO_x and PM mainly due to the significant difference in the emission factors of the built-in databases. Both tools can identify the key remediation activities that cause environmental impact, and can also compare different remediation solutions at the same time. However, both tools have certain limitations:the evaluation of economic and social indicators is insufficient; there are no sensitivity analysis functions; the indicators and built-in database may not be applicable for certain real situations. It is suggested to research and develop a suitable environmental footprint tool for domestic practical use, so as to provide further support for carbon and environmental pollution reduction in remediation activities.
