Product Eco-efficiency

Eco-efficiency

The concept of eco-efficiency was developed to realize a sustainable society by providing products and services designed to improve the quality of life while reducing environmental impact.

The Factor indicates the degree of improvement in eco-efficiency by comparing to a benchmark period. Factor values of 4 and 10 are widely known as the targets required to realize a sustainable society. The greater its Factor, the more a product contributes to creating value and reducing environmental impact through technological progress and innovation.

Toshiba Group originally developed a method for calculating eco-efficiency to introduce an indicator that enables overall assessment of products' environmental friendliness. Comprehensive activities for creating ECPs that are aimed at increasing the Factor are part of the Factor T initiative, so named after Toshiba's initial. Factor T has the following characteristics: ① it is expressed as a multiplication of a value factor and an environmental impact reduction factor; ② it quantifies the value of a product or service (numerator) using QFD; ③ it assesses environmental impact (denominator) using LIME (*).

For detailed information about the calculation method and its application to Toshiba products, see the explanatory materials (“[Factor T] Reader” and “Encouragement of [Factor T].”

LIME: One of the leading environmental assessment methods in Japan, LIME (Life-cycle Impact assessment Method based on Endpoint modeling) was developed by the Research Centre for Life Cycle Assessment, National Institute of Advanced Industrial Science & Technology, an independent administrative institution.

The Factor T initiative was started in 2003. Under this initiative, we have carried out various activities involving parties inside and outside Toshiba Group, including the announcement of Environmental Vision 2050, formulation of Environmental Action Plans, conferences with competitors aiming at standardization, and contribution to the establishment of ISO standards. Toshiba Group will continue to pursue the Factor T initiative in order to work toward realizing a sustainable society by incorporating new knowledge.

In addition to developing and promoting eco-efficiency assessments appropriate for different business areas, Toshiba Group is also working to address new international trends ahead of other companies.

Initiative in the area of medical equipment

Toshiba Medical Systems Corporation has been working to create eco-designs in the area of medical equipment. In the design of medical equipment, the highest priority is placed on clinical performance. This priority must be balanced against other requirements, such as those for energy-saving, resource-saving and space-saving performance. When installing equipment, increased product sizes often necessitate that building walls be knocked down or hallway doors be removed. For this reason, it is also important to reduce the waste generated during delivery and installation of such equipment. Toshiba Medical Systems Corporation has created a system in which competitors' products are always chosen as benchmarks and goals are set for environmental performance during the product planning and development stages. The company also takes an active part in disclosing information about improvements in products' environmental performance as product features, thereby promoting communication with customers. At the 9th LCA Society of Japan held in FY2012, Toshiba was awarded the Incentive Award for its activities promoting environmental management in the area of medical equipment through life cycle assessment.

Initiative in the water related area

From early on, the Environment Management Division has focused on the importance of water resources, which have recently been attracting attention as a critical environmental issue, and has been considering incorporating water resources into conventional LCA. We are actively promoting the use of information on water resources within group companies and also publicizing the importance of such information through various activities, including compiling data on water consumption per unit production using input-output tables, participating in the activities of external working groups, and publishing the water footprints (WFs) of products and services at Eco-products Exhibitions and in our environmental reports. In our home appliance case studies, we estimated reductions in WF resulting from improvements in the water-saving performance of washing machines with dryers and the food preservation performance of refrigerators, thereby adding value to products. We also participate in external study meetings to review water consumption management at production sites, thereby responding to international trends to develop in-house measures in a timely manner, including enhancing water management at production sites in water-stressed areas. For these water footprint activities, Toshiba Group was awarded a second Incentive Award.

Looking back on the awards ceremony

Toshiba Group has received awards from the LCA Society of Japan six times in five consecutive years. We believe these results reflect our continued efforts to assess eco-efficiency using our Factor approach. We will continue our group-wide efforts to develop and promote eco-efficiency assessment.
