Water Risk

Water risk governance

Committee MHI Group Environment Committee
Risk management measures related to water risks In the Third MHI Group Environmental Targets (FY2015–FY2017), MHI also set consistent Groupwide reduction targets in relation to the effective use of water resources, and is currently undertaking Groupwide measures. An IT system is being used for the reporting and accumulation of water-related data for MHI factories in Japan on a non-consolidated basis and for Group companies within and outside Japan.

Water risk management

Management of water quality Waste water is managed and treated in accordance with relevant laws and regulations.
Management of changes to laws, regulations, taxes, and water prices Domestically, once information on any regulation change or revision is obtained, we take appropriate action promptly as necessary. With regard to overseas factories belonging to Group companies, we are promoting the collection of data related to their water use.

Water Used During Products' Life Cycle

Products contributing to the reduction of water use For example, desalination plants for converting sea water into plain water are often built in combination with power plants constructed in Saudi Arabia, where water resources are limited. Combining our products from a wide range of areas, MHI has been delivering solutions for issues pertaining to water resources.
Relaxation of water quality effects by using products We are contributing to alleviating the influence of water quality through environment-friendly thermal power generation systems, such as wastewater treatment of desulfurization equipment.
