Hazama Corporation, a major construction company in Japan, announced on November 4, 2010, that it has developed and achieved practical use of a system called "Hazama Corporation Eco Diagnosis." The system calculates and shows methods for reducing the amount of CO2 emitted from civil engineering works.

Engineering works emit more CO2 per unit cost than building works. Hazama developed the system in order to quickly visualize the amount of CO2 emissions when making technical proposals for civil engineering works.

The system consists of (1) a program to calculate CO2 emissions, (2) a database of methods for reducing CO2 emissions. This system uses estimation data to calculate and clearly show the amount of CO2 emitted from each project and each type of construction machine. It can also calculate amounts of sulfur oxides (SOx) and nitrogen oxides (NOx), and air pollutants in smoke dust.

After calculations, the engineering proposal division then checks the database to choose the most effective way to reduce CO2 emissions and propose the technology that is most helpful in reducing emissions. Hazama intends to utilize the system not only in its Engineering Proposal Division but also in its Construction Division.
