Alpine implements internal audits twice a year to monitor environmental preservation activities. In internal audits, we confirm compliance status, regardless of whether we receive complaints from local residents, in addition to monitoring the application of environment management. As of 2006, no deviations from laws or regulations have been found, and we had not received any complaints from residents.
In addition to such internal audits, we are assessed for ISO 14001 certification by a third-party organization once a year, to conduct fully objective audits.

Since 2001, when Alpine prepared Environmental Accounting Guidelines and introduced its first environmental accounting at the Iwaki Main Office, Alpine has expanded its range to include its affiliates -- Alpine Electronics Manufacturing, Inc., and Alpine Precision, Inc. -- and has effectively used the guidelines in environmental management while simultaneously pursuing enterprise management and environmental preservation. In 2006, the Environmental Accounting Guidelines were revised to include improved calculations, taking into account the effect of environmental preservation efforts.
