Response to Climate Change

Concept of Climate Change "Adaptation"

Concept on Climate Change Adaptation

With an increasing frequency of ever more severe natural disasters striking Japan, it is extremely important to identify possible disaster risks via the development of diverse scenarios. We assume earthquakes, flooding, high tides and other emergencies so that we can minimize damage to our refineries and complexes and ensure that operations at these facilities can be promptly restored. To strengthen our ability to ensure safety, we will therefore direct capital expenditure to upgrade facilities, while enhancing operational procedures and human resource capabilities, to mitigate damage even in the event of a disaster with unprecedented severity. By doing so, we will continue to fulfill our mission as an energy supplier.

In recent years, a growing number of typhoons have passed through a large part of the Japanese archipelago while remaining at full strength. This phenomenon is believed to be due in part to climate change. As these typhoons often induce high tides, our refineries and complexes located in coastal areas are facing a growing risk of flooding. In response, we have conducted risk analysis associated with the impact of flooding due to high tides based on the simulation of typhoons of the largest-possible scale taking courses that directly cross these facilities’ sites. Based on the results of this analysis, we are considering the reinforcement of facility structures via, for example, the installation of flood walls to safeguard seawater pump rooms in addition to the enhancement of disaster response manuals and other procedures designed to provide our staff with guidance on how to mitigate disaster damage.
