Internal Environmental Audit
-
Internal audits of environmental initiatives are conducted across all departments by "internal environmental auditors" certified through specialized training. All defects discovered during the audits are corrected and used to improve environmental management. In addition, regular training is provided to auditors to enhance their skills. The Environmental Promotion Department in Japan also conducts regular audits of our four overseas factories to ensure that environmental initiatives are carried out at the same level globally.
