As global warming escalates, heatwaves, droughts, and wildfires are becoming more frequent and severe. Driven by glacial melting and the thermal expansion of seawater, rising sea levels are increasing coastal flooding risks, alongside heightened risks of heavy rainfall and flooding. Moreover, the impact of climate change extends beyond natural disasters. Loss of biodiversity is expected to reduce future ecosystem services, increase flood and landslide risks, exacerbate resource depletion, and worsen water quality.
Climate change and biodiversity loss are expected to have a significant impact on the activities of many companies. They are also impacting the underwriting practices of the insurance industry upon which companies depend. Accordingly, the MS&AD Insurance Group has identified “Symbiosis with the Global Environment — Planetary Health” as a priority issue and is advancing initiatives to address climate change and enhance the sustainability of natural capital in an integrated way. Through its insurance products and services, the Group is actively promoting disaster prevention and mitigation, while also advancing adaptation to climate change. To support the transition toward Net Zero by 2050, the Group has set greenhouse gas reduction targets and is working to reduce GHG emissions from its own operations. In addition, the Group is also maintaining dialogs with client companies to deepen its understanding of the challenges they face in reducing greenhouse gas emissions and is working with them to address these challenges.
We need to develop initiatives for mitigating advancing climate change while also putting in place measures to prepare against rising risks. The Group will provide society with safety and peace of mind through effective preparatory measures, including reinsurance for loss due to large-scale disasters. We will also support new businesses which lead to realization of a net-zero society, promoting climate change adaptation by providing appropriate services to reduce or eliminate damage and loss inflicted on customers by natural disasters.
