Joint development of eco-efficiency indicators by Hitachi and Matsushita, 2003 approx.

Around 2003, Japanese companies were at a turning point in their efforts to redefine environmental impact reduction from a social responsibility to a source of competitiveness. With the ratification of the Kyoto Protocol, greenhouse gas reduction became an international obligation, and there was growing pressure, particularly from the manufacturing industry, to "visualize" their environmental impact. Against this backdrop, Hitachi, Ltd. and Matsushita Electric Industrial jointly developed an eco-efficiency index to quantify the relationship between product value and environmental impact, and a factor index to indicate the improvement multiplier. Eco-efficiency is based on the concept of dividing product value by environmental impact, and is characterized by its ability to evaluate efforts to reduce environmental impact while maintaining or improving value, rather than simply reducing impact. In addition, it also covered environmental impacts outside the use phase, such as man
ufacturing and transportation, and was positioned as a standard to consistently assess the entire life cycle of a product. These indicators were expected to unify environmental standards among companies, increase the transparency of environmental reports, and be introduced into employee training. At the time, environmental regulations such as the RoHS and WEEE directives were being strengthened in Europe, and Japanese companies were also faced with the need to demonstrate their environmental performance in the face of international competition. The joint development by Hitachi and Matsushita was a pioneering effort that led to the development of a common language for environmental information and to CSR and ESG evaluations in later years.
