In order to strengthen national adaptive capacity, decrease the social vulnerability, and establish integrated climate change adaptation operating platform, the National Climate Change Adaptation Policy Framework had been approved by the Executive Yuan in 2012. Based on the framework, the National Action Plan on Climate Change 2013-2017 has been implemented to form an inter-departmental and policies-supporting operational platform. The implementation of Greenhouse Gas Emission Reduction and Management Act on July 1st, 2015 signaled the start of a new era of promoting comprehensive strategies to face the challenges of climate change in Taiwan. In response to the progessing of international climate change convention and the implementation of national adaptive policies, the project aimed to analyze environmental impact and vulnerability assessment methods for environmental, social and economic effectiveness after adopting environmental adaptive policies. In this project, the progress of Paris Agreement and national climate change adaptation strategies of the UK, Netherlands, Japan, Korea and China were researched to find out the international actions dealing with climate change. Furthermore, the current implementation mechanisms, water resources action plans and land use action plans were reviewed to improve the climate change actions of Taiwan. Lastly, the national and international quantitative assessment tools were introduced for policy assessment in the future. Case study of water resources assessment in urban areas of northern Taiwan and land use assessment in Tainan City （both urban and non-urban areas） were provided to illustrate the application of the tools for operation-supporting mechanism of impact assessment and adaptation for climate change.
