Expanding Environment-friendly Products and Services

 The Kubota Group is contributing to protecting global environment and solving social issues in the food, water and living environment fields through the provision of environment-friendly products and services. The Group conducts environmental assessment of products in the design and development stages, and promotes environment-friendliness over the entire product life cycle, from the procurement of raw materials to the disposal of products. The Group also internally certifies exceptionally environment-friendly products as Eco-Products, and is working to expand its lineup of certified products.

Environmental Considerations in the Product Life Cycle

1. Major Initiatives to Ensure Environment-friendliness



2. Analysis of Environmental Loads in the Product Life Cycle

 The Kubota Group handles a diverse range of products, from agricultural and construction machinery to pipe systems and water treatment equipment. As part of its product environmental assessment, the Group conducts life cycle assessment (LCA) for its major products to determine the amount of greenhouse gas emissions over each product life cycle.

Results of LCA: Proportions of Greenhouse Gases
  • LCA results for tractors were calculated based on the assumption of towing and transporting work for 5,000 hours by the M9540DTHQ-EC agricultural tractor in France.
  • LCA results for ductile iron pipes were calculated based on the data reported in the “Study on Piping Technologies for Sustainable Water Supply Service” (Japan Water Research Center).
    The proportions of raw material procurement, manufacturing, and product transportation were determined according to Kubota’s CO2 emissions data.

 Greenhouse gases emitted in the use stage account for around 90% in the life cycle of agricultural tractors, while gases emitted in the manufacturing and construction stage account for around 90% in ductile iron pipes. Thus the frequency and scale of environmental loads in the life cycle vary depending on the product type. The Kubota Group enhances its environment-friendly products and services by reflecting the results of the analysis of environmental loads in the product life cycle in its environment-friendly design development.

Internal Certification System for Eco-Products

1. Regarding the Internal Certification System for Eco-Products

 The Kubota Group's internal certification system for Eco-Products was introduced to internally certify products with exceptional environmental friendliness. We evaluate products in accordance with matters related to the five basic items for environmental conservation in the Kubota Group’s environmental management, namely, “Tackling Climate Change," “Working towards a Recyclingbased Society," “Conserving Water Resources,” “Controlling Chemical Substances,” and “Conserving Biodiversity,” and certify those products that satisfy our internal standards as Eco-Products.



2. Eco-Products Certification Committee

 Eco-Products Certification Committee, chaired by the General Manager of the Manufacturing Headquarters, consists of the committee members elected from each Division, as well as the Research and Development Management Department and the Environmental Protection Department Upon receiving an application from each Division for the certification of a product, the Committee examines the product’s adequacy as an Eco-Product and gives certification.




3. The Pathway to Expanding Certified Eco-Products

 Based on the internal certification system established for Eco-Products, the Kubota Group certified additional 34 products in RY2017, bringing the total number of certified Eco-Products to 198. The sales ratio of Eco-Products was 55.6%. We will continue to carry out initiatives focusing on the development of environment-friendly products and expand our Eco-Products lineup.

The Evolution of Environment-friendly Products and Services

1. The Evolution of Scales

 Since its foundation, the Kubota Group has manufactured cast metal parts for scales. After starting manufacturing mechanical platform scales in 1924, the Group has produced various industrial scales, contributing to the improved efficiency of manufacturing by companies. At manufacturing sites today, technological innovations using huge data, such as IoT and AI, have been rapidly advancing. We will continue to support the manufacturing sites by further sophisticating its measuring and weighing technologies to obtain accurate data.


The Evolution of Scales and Expansion of Uses

 The Kubota Group has evolved its scales from mechanical platform scales to load cells, which make use of metal strain, and to the development of digital load cells, which can directly output digital signals, satisfying the needs of customers. Today the Group’s scales are used for various purposes.



The Evolution of Platform Scales

Platform scales have evolved into easy-to-use, environment-friendly platform scales with high accuracy, reduced weight, and improved energy-saving performance.
