Abstract
In Taiwan the development of strategic environmental assessment (SEA) is on initial stage. There are a few finished cases for SEA, and most of them use qualitative analysis to estimate environmental impact. A qualitative method results in a subjective decision, so it is necessary to establish a quantitative tool in the procedure of SEA in Taiwan.
A framework for SEA tested in a case study on a regional waste management includes the test of developing quantitative method such as traditional life cycle assessment (LCA) for impact assessment in SEA and site-dependent human toxic potential (sd-HTP) for human health in life cycle impact assessment (LCIA). Because of the lack of site-dependent information in traditional LCA method, adding sd-HTP will increase the accuracy of the model. The results of LCA indicate that the electric recycle in the incinerating process reduces environmental impact, and sd-HTP with local geography and exposure parameters affects numerous differences from traditional LCIA in human health category.
In the end, integrating the LCA results into matrix is a proper way at present to establish a quantitative tool in the procedure of SEA. However the results of LCA can not cover all relevant types of environmental impacts. Therefore it would be useful to complement a traditional LCA with a structured qualitative approach in order to take into account all of the matrix items.
