IPCC 5th Assessment Report on Climate Change for Policymakers further affirms the continuing trend of global warming and their observed geophysical effects (IPCC, 2013). Thus, it is important to understand the impacts of changing climates and increasing disaster risks on our built environment, in particular, develop adaptation pathways to mitigate the impacts through the nexus of climate-conscious design standards, planning and policies. Firstly, the implications of climate change to built assets is presented, and an approach to develop resilient engineering structures by enhanced design standards to maintain durability under changing climate is then introduced. Secondly, an integrated approach is demonstrated to develop timely and spatially targeted regional coastal planning to mitigate the impacts of coastal inundation under sea level rise and increasing extreme winds. Finally, a large-scale reactive and proactive intervention options to mitigate coastal inundation, extreme winds and bushfire at a national scale are examined in terms of cost and benefit for the development of national adaptation policies.
