Abstract—Strategic environmental assessment (SEA) is a systematic decision support process by which environmental, economic and social considerations are considered effectively in policy, plan and programme. Taiwan SEA involves eight categories and 33 criteria. One of the objectives of SEA is to establish indicators and to select the most appropriate alternative of possible policies. Once the indicators are established, a comprehensive evaluation of each alternative can be conducted to determine whether the main policy is the most preferred. A total of 28 Taiwan SEA cases, from 2001 to 2016, are reviewed policy EIA specifications from 1990 to 105 and the result shows that most of the cases did not have a clear comprehensive assessment method. Another type of 7 cases has a clear and comprehensive assessment method, which is AHP. However, if their indicators are classified according to the sustainable development model, Drivers-Pressures-State- Impacts- Response, the relationship between indicators should be networked, non-independent, causal, and some indicators are midpoint and dome are endpoints, they are therefore not applicable to AHP because of double counting. Moreover, the impact of a policy is extensive, in addition to the direct effects on the regions in which the policy is implemented, the indirect and cumulative effects on the region and even the global should be considered. Therefore, the life cycle sustainability assessment (LCSA), involving Life cycle assessment (LCA), Life cycle costing (LCC) and Social life cycle assessment (S-LCA), is used as the impact assessment tool for SEA because it can establish the impact pathway of its life cycle sustainability impact assessment (LCSIA) to clarify its causal relationship and midpoints and endpoints. Based on the midpoint indicators, the indicators for SEA are developed.
