The risk associated with water resources called “Water Risk” is less likely to develop than the others, but there will be serious damage to our daily life if it occurs. For example, Thailand Floods 2011 damaged the supply chain from component provision including a production step to physical distribution of products. Eventually, the total financial damage was extensive. Addressing the threat of “Water Risk” is now perceived as an urgent issue at the level of not only countries but also enterprises. In Japan, the stakeholders asserting influence over enterprises are getting more interested in addressing (or mitigating) this kind of risk because of typhoon and localized heavy rain with the high frequency of occurrence.
In this manuscript, the author gives considerable attention to the assessment of “Water Risk” by enterprises and conducts trend analysis for their recognition and attitude. In this process, the information recorded on ESG Dialogue Platform established by the Ministry of the Environment (Japan) is used for analysis instead of the information included with environmental reports announced by each enterprises. It is noted that the proposed approach is different from the previous ones. The advantage of using the information on ESG Dialogue Platform is to facilitate the analysis.
According to the Ministry of the Environment, “Water Risk” is divided into three categories “physical risk”, “regulatory risk” and “reputation risk”. The classification seems to be connected to the identification based on the manageable level by enterprises. In accord with this point, the author formulates the hypothesis that there is the trend to proactively record something about “physical risk” having the highest degree of involvement. The main objective of the analysis is to determine the authenticity of the hypothesis.
