Green Purchasing

Taking the environment into account from the purchasing stage, we make a point of using products and services with a low environmental impact. 

We’ve established extensive assessment criteria for green purchasing to make our decisions as fair and equitable as possible.

The Green Purchasing Network (GPN) encourages companies to make procurement decisions with an eye to the environment by giving preference to products and services with a lower environmental impact. Recognizing the important environmental role the network plays, NTT DATA Group is proud to be a corporate member of GPN on the purchasing side and is actively committed to green purchasing. Green purchasing can have a big impact on the companies (vendors) of which we are customers, and it has countless social ramifications. However, unless it is pursued in a fair and equitable manner it can lead to real abuse. For this reason, we have built our purchasing system on the following principles.

Green Purchasing Mechanism (conceptual diagram)

We select vendors based on an overall evaluation including price, quality and the Green purchasing criteria which is the rating of the vendor's corporate responsibility and the product's environmental impact.

Outline of Green Purchasing Assessment System

1. The environmental rating is the vendor CSR rating and the product rating combined.When the vendor does not deal in physical products, the CSR rating alone serves as the environmental rating.


2. In general, the relative weight of CSR and product in the final environmental rating is 50 : 50.


3. When the vendor is a distributor and not the manufacturer, the CSR rating is derived by totaling the manufacturer’s and distributor’s ratings, weighted 60 : 40.


4. If the overall environmental rating is 50 or below, the environmental manager is notified and necessary measures will be drawn up.
