Abstract
Three years have passed since Japan general contractors were awarded the ISO14001 certification in 1997for the first time in the country's building sector. Since then, the number of companies to be awarded with ISO14001 certification has increased drastically There are signs that the number of companies that will be awarded the certification following this 1997 will further increase considerably, with the focus not only on the general contractors but also on other sectors such as the sub-contractor sector This report attempts to introduce the effective implementation based on ISO 14001 and the matters and issues in the Japan building industries.
