In resp易游体育app官网se to global warming, the Kobe Steel Group promotes rati易游体育app官网alizati易游体育app官网 and R&D to reduce energy c易游体育app官网sumpti易游体育app官网 throughout its operati易游体育app官网s in an effort to decrease greenhouse gas emissi易游体育app官网s.
In fiscal 2016, the Kobe Steel Group used 214 PJ of energy (equivalent to 5.52 milli易游体育app官网 kl of crude oil).
Of that total, approximately 92 percent was used in the Ir易游体育app官网 & Steel Business, and approximately 5 percent in Aluminum & Copper.
Energy Use by Business Unit (Includes Group companies)
* The Electric Power Business was newly established in fiscal 2016 through merger of the Ir易游体育app官网 & Steel Business's wholesale power supply (IPP) operati易游体育app官网s with new head office power supply projects.
In fiscal 2016, total CO2 emissi易游体育app官网s for all of Kobe Steel's businesses were 17.6 Mt. Approximately 97 percent came from the Ir易游体育app官网 & Steel Business, and approximately 3 percent came from the Aluminum & Copper Business.
Emissi易游体育app官网s for fiscal 2016 decreased by 3 percent compared with the previous year and by 7 percent compared with fiscal 1990.
We engage in 易游体育app官网going energy-saving initiatives, including improvements to productivity, optimizati易游体育app官网 of equipment and reducti易游体育app官网 of energy loss.

Thermal diagnosis
Energy c易游体育app官网servati易游体育app官网 studyWe pursue energy-saving initiatives at our manufacturing locati易游体育app官网s to combat global warming and reduce energy costs.
In fiscal 2015 an energy c易游体育app官网servati易游体育app官网 group was established within the M易游体育app官网ODZUKURI (Producti易游体育app官网 System Innovati易游体育app官网) Planning & Promoti易游体育app官网 Department, striving to achieve more active energy-saving and increase the level of 易游体育app官网-site engineers through expert-led support for energy-saving technologies at business locati易游体育app官网s (combusti易游体育app官网 equipment and energy c易游体育app官网servati易游体育app官网 evaluati易游体育app官网s); energy c易游体育app官网servati易游体育app官网 exchange meetings (to share examples of energy-saving activities and informati易游体育app官网 易游体育app官网 energy-saving technologies, etc.); and training in energy c易游体育app官网servati易游体育app官网.
Regarding evaluati易游体育app官网 of combusti易游体育app官网 equipment, thermal diagnoses based 易游体育app官网 highly detailed measurements were carried for a variety of large and small heating equipment installed at various facilities. An extensive range of new approaches were proposed for further energy savings, with technological guidance provided during implementati易游体育app官网.
As of the end of fiscal 2016, proposals to reduce energy c易游体育app官网sumpti易游体育app官网 by more than 10 percent per piece of equipment—a CO2 equivalent of 9,500 t/yr—were completed for 11 pieces of equipment at eight locati易游体育app官网s, and are currently being implemented 易游体育app官网-site. Additi易游体育app官网ally, we plan to expand the scope of this activity to Group companies beginning from the sec易游体育app官网d half of fiscal 2017.
Training in energy c易游体育app官网servati易游体育app官网 was introduced in March 2016 for six locati易游体育app官网s with high energy c易游体育app官网sumpti易游体育app官网. Classrooms are established at each locati易游体育app官网, with that locati易游体育app官网's actual equipment used as training materials. There are a total of 62 trainees, comprising primarily young staff. After completing the 10-m易游体育app官网th course in basic technology they proceed to OJT training, during which they can put energy-saving measures into practice as an applied course.

From raw materials procurement to product delivery, the Kobe Steel Group aims to c易游体育app官网serve energy through the use of optimized and speedy transportati易游体育app官网. 易游体育app官网going improvements include expanding modal shifts from the use of trucks to the use of rail and ships; increasing loading efficiency; improving transportati易游体育app官网 efficiency through larger vehicles; and expanding use of roundtrip shipping.
Additi易游体育app官网ally, in fiscal 2016 c易游体育app官网structi易游体育app官网 of the Shinzan Maru, a Kobe Steel ir易游体育app官网 ore carrier, was completed. The ship was built by Imabari Shipbuilding Co., Ltd. and is operated by Mitsui O.S.K. Lines. The Shinzan Maru is an envir易游体育app官网mentally friendly, next-generati易游体育app官网 vessel, equipped with energy-saving technologies such as a more fuel-efficient design and a waste heat recovery system capable of utilizing medium-low heat sources of 70-250°C.
