Eco-Efficiency and Factor

Overall eco-efficiency

Environmental Vision 2050 requires Toshiba Group to increase the degree of improvement in overall eco-efficiency ten times (Factor 10) by FY2050 compared to the FY2000 level.
Toshiba Group's overall eco-efficiency is calculated by combining product eco-efficiency and business process eco-efficiency. The overall eco-efficiency in FY2019 was 2.60 times the FY2000 level (Factor 2.60). Progress has been made especially in product eco-efficiency by creating high energy-saving products and services. In FY2020, we will continue to achieve further improvement.

Product eco-efficiency (Factor T)

Toshiba Group originally developed a method for calculating eco-efficiency to introduce an indicator that allows overall assessment of products' environmental consciousness. Comprehensive activities for creating ECPs*1 that are aimed at increasing the Factor are part of the Factor T initiative, which was named using the first letter from Toshiba's name.

Factor T is expressed by multiplying a value factor, which represents a product's degree of improvement in value, with an environmental impacts reduction factor, which represents the degree of environmental impacts. The value factor quantifies the value of a product or service using QFD*2, while the environmental impacts reduction factor assesses environmental impacts using LIME*3.

*1
ECP: Environmentally Conscious Products
*2
QFD: Quality Function Deployment is a standard tool used in product design.
*3
LIME: Life-cycle Impact assessment Method based on Endpoint modeling developed by the Research Center for Life Cycle Assessment, the National Institute of Advanced Industrial Science and Technology (AIST) as a method integrating various environmental impacts.

Business process eco-efficiency

Toshiba Group is striving to reduce environmental impacts by assessing the effect of environmental impacts on business activities and ranking the degree of improvement from the benchmark year as business process eco-efficiency.
