Environmental Assessments

Environmental Assessments of Domestic Construction Sites

JGC conducts an annual evaluation of environmental performance at its construction sites in Japan based on three criteria: industrial waste recycling rate, number of contaminant leaks and CO2 emissions per unit of energy.

In fiscal 2017, JGC made good progress, achieving its internal environmental targets through concerted efforts across its project sites. Although one leak incident occurred in fiscal 2017, it was reported immediately to the relevant authorities, followed by prompt, appropriate action, essentially preventing external damage.

However, CO2 emissions per unit of energy during fiscal 2017 increased relative to the previous fiscal year, due to the frequent use of power generators at sites without a power supply, an increase in large-scale projects with a high proportion of civil engineering work, and an increase in the use of construction machinery and equipment.

In terms of the adoption rate of electronic manifests, although the basic policy is to select vendors that support electronic manifests, the adoption rate is lower than last year, due to a lack of transport vendors or intermediate processing vendors capable of supporting electronic manifests in some of the regions where projects were under way.
