Environmentally Friendly Products and Services

Basic Approach

The products and services that the Daifuku Group provides to society through its customers have an impact on the global environment through the use of electricity and resources. We recognize that responding to the demands for more environmentally friendly products and services that transcend national and organizational boundaries is an important issue to ensure the continuation of our business, and we aim to maximize the value we provide to our customers through an expansion of our environmentally friendly products and services.

Promotion System

The Environmental Management Subcommittee,* established under the auspices of the Sustainability Committee, discusses and examines issues like contributing to a reduction in CO2 emissions through our products and services, environmentally friendly projects, and Daifuku Eco-Products certification.
In fiscal 2022, the Product Evaluation Project was launched under the auspices of the Environmental Management Subcommittee, and consideration has been initiated to visualize product value from a broad sustainability perspective that includes not only environmental friendliness, but also contributions to our customers and to society in general.

  • *This Subcommittee is a merger of the Environmentally Friendly Products Subcommittee and the Environmentally Friendly Operations Subcommittee, which had existed until fiscal 2021.

Major Initiatives

Daifuku Eco-Products Certification Program

In 2012, Daifuku began its Daifuku Eco-Products Certification Program to certify products based on environmental impact assessment ratings and a certification system using Daifuku’s own standards. Under the program, all products across the Group are measured under the same standards, with measurements coming from results of a Life Cycle Assessment (LCA) and environmental performance assessments on a number of areas, including power saving, recyclability, lightweight, long Life, packing material reduction, water conservation, noise reduction, water pollution prevention, and harmful substance reduction. As of May 2022, 77 products have met the standards and been certified as Daifuku Eco-Products.

Moreover, starting in fiscal 2022, we have been reviewing this system through the Product Evaluation Project of the Environmental Management Subcommittee. In addition to concern for the environment, we are examining the product evaluation axis from a broader perspective that includes contributions to our customers and society.

Certification process

To obtain a valid and trustworthy rating from multiple perspectives, the screenings are done by the certification meeting, comprised of directors or chief operating officers from different operations.

Avoided CO2 emissionsKPI

We are reducing CO2 emissions from energy use during product operations with our environmentally friendly products and services that conform to our Group's standards. Our CO2 reduction amount is calculated by subtracting the CO2 emissions produced from our products/services provided to our customers from the CO2 emissions produced from our products/services in fiscal 2011—the base year for environmental performance.

  Scope FY2021
Avoided CO2 emissions through products/services Global 69,694 t-CO2

Life cycle assessment

Daifuku conducts environmental impact assessments of all products using the LCA analytical tool in order to determine the environmental footprint of our products throughout their lifecycle and to continuously develop environmentally conscious products. Comparing old and new products helps us to enhance the environmentally-friendly design of our products and services.

Case studyLCA results for Mini load AS/RS - Fine Stacker (H-P10), an automated box warehouse

The Fine Stacker, an automated box warehouse, is a product that automatically receives, stores, and retrieves small quantities of various irregularly-shaped products and parts in the form of containers, cardboard boxes, or trays. The H-P10 is a high-capacity model suitable for multi-tenant distribution warehouses, with a lightweight main unit and a specialized transfer machine that reduces transfer time.

1. LCA computation scope

  • LCA
  • The Fine Stacker

For the portion of the stacker crane that makes up the H-P10, we calculated receiving and retrieving operations for 12 years, within the range of resource extraction to shipment for recycling used products.

2. Impact assessment

Impact assessments were conducted by life cycle stage for each of the six impact areas shown in the graph below. We also compared old and new products by impact area.

Summary of impact assessment by product life-cycle stage
Impact assessment
  • For waste and water consumption, the material manufacturing and assembly stages accounted for more than 90% of the impact.
  • About 70% of the impacts on climate change and energy consumption occurred during the use phase.
  • In all areas studied, the impact of the transportation and disposal phases was found to be low.
Comparison of CO2 emissions (impact area: climate change)
Comparison of CO2 emissions

The H-P10 emits 26% less CO2 than its predecessor (R-F10) due to reductions in raw materials, the number of parts, and power consumption during use.
