Hitachi Construction Machinery Group is focusing on the reduction of paper usage in green procurement and is making efforts to lace the highest priority on promoting paperless initiatives, encouraging greater use of double-sided and more intensive printing methods ^*1 using recycled paper when use of paper is essential, and is working in the introduction of scheduled printing methods ^*2. 

∗1 Printing multiple pages on single paper sheets
∗2 A method in which data is saved in the printer without being immediately output onto paper media. When required, the user’s finger authentication is performed on the printer side, and printing is carried out.
In this method it is possible to further prevent unnecessary paper output as printing mistakes can be canceled at the time using finger authentication.

The Hitachi Construction Machinery Group considers protecting the water bodies that receive the effluents from factories is an important issue.
In order to prevent water contamination, we have put in place independent standard values even more stringent than the pollution prevention agreement values set by national and local governments, and in addition to daily water quality inspections, we have installed automated measuring devices which can be regularly monitored, implemented a strict management structure, and maintain and manage the quality of waste water from operations.
We strictly control water discharged through wastewater treatment systems, and install biological treatment depending on wastewater quality.

We regularly monitor BOD and COD emissions complying with pollution prevention agreement values set by each national and local government.
