Implementation of Environmental Audit at Toshiba Group

Implementation of Environmental Audit at Toshiba Group

Since 1993, the Toshiba Group has been conducting regular environmental audits covering most sites of Toshiba and its Group companies through its proprietary Toshiba Group Environmental Audit System. This system is based on the "3 Zen (all) approach," which promotes management of all facilities in all areas by all employees; the "3 Gen (actual) approach," which emphasizes measurement of the actual situation of actual items at actual plants; and the “visual control” approach, which includes, for example, the practice of labeling every piece of equipment to indicate its proper status so that it can be checked easily in the field for compliance.
Audits at manufacturing sites, called "site environment audits," are executed every other year (*1) at all manufacturing sites in Japan and every year at sites outside Japan.
The audit is conducted for two days by an audit team that consists of qualified auditors from within the company. The sites receive audits on the following items: 1) environmental management, 2) legal compliance and 3) plant management, as displayed in the figure below. The plant audit, in particular, is conducted at 19 facilities and includes checks of waste water treatment equipment, recycling, and chemicals warehouses and facilities that use chemicals, as well as training for handling emergency situations. Compliance, measurement control, 4S (Seiri, Seiton, Seiketsu, and Seisou, meaning in English: sorting (removing unnecessary things), straightening (keeping things orderly and available as needed), sanitation, and sweeping (maintaining a clean workplace)), and employee education are also strictly monitored. Any audited site which receives instructions for improvement, if any, must implement corrective measures within six months.
Aiming to improve the environmental performance by deploying the Toshiba Group Environmental Audit System, the Toshiba Semiconductor & Storage Products Company Group has structured the environmental management system in accordance with ISO 14001. We promote this through compliance with various laws and regulations and through mitigation of environmental impact at work sites, so that these two environmental audit targets are inseparable.

  • *1: Some domestic operations with higher environmental impact are audited annually. The operation sites that are audited biennially conduct a self-audit every other year between the official audits.

Roles of Toshiba Group Environmental Audit System and ISO 14001

The results of Toshiba Group Environmental Audit System implemented in FY2012

The Semiconductor & Storage Products Company has obtained fine results in its internal Toshiba Group Environmental Audit System by promoting continuous improvement in environmental performance.
The results of Toshiba Group Environmental Audit System are assessed in alphabetical grades. While the number of companies that have obtained the highest level of “A” in both the environmental management audit and plant audit in FY2012 is 42% throughout the Toshiba Group, it is as high as 94% in the Semiconductor & Storage Products Company Group.
The reasons for the high ranking of the Semiconductor & Storage Products Company Group include both the effective utilization of the environmental management information system to share data on good environmental practices throughout the group companies, and global improvement of the management system by the implementation of measures that also comply with ISO14001.

Specific examples of findings at Toshiba Group Environmental Audit System

Here are some specific examples of the findings of Toshiba Group Environmental Audit System auditors from audits conducted at sites of the Semiconductor & Storage Products Company Group in the previous fiscal year. In addition to detailed checks on the audit items at applicable facilities, all sites adopted systematic measures in response to the findings and recommendations within 6 months of the audits. Positive findings are shared horizontally throughout the entire organization using the environmental management information system.

Examples of a recommended improvement

Improve visibility (location and letter size) of the safety display for employees at gas facilities that use special gases. (The display was improved in response to the auditor’s note.)

Good example

At an emergency drill in front of the chemicals warehouse, everyone was well trained, and the drill was conducted quickly and calmly.
