Climate change induced by global warming may cause several patterns of economic losses. It is important to estimate the aggregate net economic costs of damages across the globe in order to assess the threshold level of temperature rise and the stabilized level of greenhouse gas. A new approach is presented to quantify economic risk using GIS platform based on the assumption that the economic loss is proportional to both the magnitude of the disaster and the asset density of the effect area. The way of estimating property is proposed and the data sources is shown in Japan. An example is given for practical estimation of the asset distribution.
