Climate friendly technologies contribute to tackling global climate crisis and the dynamic transfer of these technologies is important to achieve universal climate actions. The UNFCCC, and its recent Paris Agreement, have introduced international assistance to promote climate related-technology transfer. They call for collaborative actions from both technology supplier and demander sides in order to enable environments for a meaningful and effective technology transfer. According to the UNFCCC, the international technology assistance is unlikely to work in a desired way with the absence of indigenous enabling environments. Therefore, it is crucial to identify, assess and overcome potential barriers potentially confronted by host countries in their acquisition of climate technologies, which helps prepare these countries for climate resilience economy and sustainable development. This paper attempts to provide a deep and comprehensive analysis on enabling policy/law environments in host countries and uses Asian countries as examples in most occasions.
