| Popis: | 105 Strategic environmental assessment (SEA) is a systematic decision support process, aiming to ensure that environmental and possibly other sustainability aspects are considered effectively in policy, plan and programme making. There are some issues in this study. Firstly, the majority (75%) of the domestic SEA cases do not make a comprehensive assessment and thereby they do not provide a scientific decision-making tool to support the main policy surpassing other alternatives. Secondly, although a small part (25%) of the domestic SEA cases are evaluated comprehensively, but some indicators such as pollutant emissions and resource consumption are stress indicators within DPSIR model, which are difficult to understand their impacts. Thirdly, if midpoints/endpoints in LCSA are used as impact indicator for SEA, some indicators of LCC and S-LCA fail to take into account the impact of the economy and society at the regional or national level. Life cycle assessment (LCA) is a damage-oriented impact assessment method, it applies midpoints/endpoints as its environmental impact indicators. In recent years, it has been gradually applied to Environmental Impact Assessment (EIA). In Taiwan, seven cases of domestic SEA using AHP as the overall comprehensive decision-making process, also utilized LCA as a part of environmental indicators. Nevertheless, the Life cycle sustainability assessment (LCSA) involves Life cycle assessment (LCA), Life cycle costing (LCC) and Social life cycle assessment (S-LCA), which considering environmental, economic and social aspects at the same time. Compared to LCA, LCSA is the more suitable impact assessment tool for SEA. This thesis has the following objectives: (1) to review literature to find relevant indicators and then classify them into environmental, economic and social groups; (2) to define impact indicators as the key indicators in the DPSIR model; and (3) to modify life cycle sustainability assessment (LCSA) as the comprehensive assessment method for SEA. According to the index system developed in this study, the 28 SEA cases are reviewed and quite few cases meet the recommended indicators in this study. Finally, the evaluation framework of two SEA cases are detailed suggested. |
