At Hitachi Construction Machinery Group, we are focusing on the development of clean technologies from the perspective of energy-saving, low-carbon and decarbonization, and are also further promoting the development of “environmentally conscious products” that help to reduce environmental impact from the product development and design stages.
Based on this approach, in FY1999, Hitachi Construction Machinery Group introduced evaluation using Design for Environment (DfE) Assessment specifying standards for development and design with consideration for the environment. At present, products developed and designed based on a new Environmentally Conscious Design Assessments compliant with the IEC62430*1 global standard are treated as “environmentally conscious products” and we are working with the aim of increasing the “environmentally conscious product sales ratio” which is the percentage of sales revenue accounted for by environmentally conscious products.
This assessment also conducts life cycle assessment (LCA) of the environmental impact of products, and quantitatively calculates not only amount of energy use and CO2 emissions related to materials, production, shipping, product use and disposal, also the amount of water use, fuel use, and materials use.
