High-efficiency Manufacturing

Pursuing the world's lowest level of environmental impacts

Toshiba Group is promoting Greening of Process, an initiative for high-efficiency manufacturing, which aims to minimize resource inputs in production processes in Japan and abroad, eliminate waste in manufacturing processes, and reduce to a minimum emissions into the atmosphere and waters, thus achieving the world's lowest level of environmental impact. Specifically, this initiative consists of two efforts: “improvement of plant efficiency,” which refers to efforts to grasp energy consumption appropriately in order to ensure effective improvement of equipment operation and introduce high-efficiency equipment, and “process innovation,” which aims to achieve sustainable manufacturing in collaboration with all units involved in manufacturing.

Toshiba Group is promoting the Greening of Process initiative from three perspectives: mitigation of climate change, effective use of resources, and management of chemical substances. In terms of climate change, the CO2 emission coeffcient for electricity in Japan has deteriorated considerably due to the effects of the March 11, 2011 Great East Japan Earthquake, and indications are that this is greatly affecting Toshiba Group, where electricity-derived CO2 emissions account for a majority of total GHG emissions. Toshiba Group is actively taking energy conservation measures on a company-wide scale. We will grasp energy consumption in real time (visualization), analyze data (easy-to-understand), and take actions for improvement (motivation). Especially in FY2013, the Group plans to reduce CO2 emissions by approximately 60,000 tons by concentrating efforts on semiconductor plants, which account for nearly half of the Group's total GHG emissions. In terms of effective use of resources, we will continue to make maximum use of our ingenuity to reduce the total volume of waste generated and final waste disposal volumes as well as strive to use valuable water resources effectively. As for management of chemicals, the Group will make efforts to reduce the amount of targeted substances handled and discharged mainly through the introduction of alternative substances and process improvements. In the future, we will endeavor to achieve the world's lowest level of environmental impacts by realizing high-efficiency manufacturing that enhances our business competitiveness.

Increasing business process eco-efficiency to 1.5 times the FY2000 level in FY2015

Toshiba Group, which comprehensively assesses the effects of environmental impacts in its business operations, views business process eco-efficiency as an important indicator of high-efficiency manufacturing and is working to reduce environmental impacts in manufacturing processes.

Results of FY2012

Sales decreased in FY2012 compared to the previous year. However, due to reductions in GHG emissions through energy conservation efforts and other factors, business process eco-efficiency improved compared to the previous year to 1.39 times (in comparison with the FY2000 level), exceeding the goal of 1.35 times.

Future initiatives

The goal of the Fifth Environmental Action Plan is to increase business process eco-efficiency to 1.5 times compared to the FY2000 level in FY2015. To achieve this goal, Toshiba Group will work to reduce environmental impacts according to the nine specific targets.
