Toshiba Group Environmental Audit System

Since 1993, the Toshiba Group has been conducting regular environmental audits covering its sites annually, through its proprietary Toshiba Group Environmental Audit system. An audit team consisting of qualified internal members conducts this audit for 2 days, based on the following principles: 3 “Zen (all)" approach, 3 “Gen (actual)" approach, and visual control (management to watch and show) approach. The audit items cover 1) environmental management, 2) legal compliance and 3) plant management, or more specifically, workplace management at 19 facilities e.g. checks of wastewater treatment equipment, recycling, and chemicals warehouses and facilities that use chemicals, effectiveness of emergency drills, compliance, measurement control of legally controlled substances, 4S (sorting, straightening-up, sanitation, and sweeping) approach, implementation status of employee education, etc.

Every year, in each manufacturing site of Toshiba Memory Corporation, we conduct a Toshiba Group Environmental Audit. With an emphasis on workplace management, the auditors examine achievement levels of energy saving, reduction of chemical substance emissions, reduction of waste, etc.
