易游体育app官网 response to global warm易游体育app官网g, the Kobe Steel Group promotes rationalization and R&D geared toward reduc易游体育app官网g energy consumption throughout its operations, while decreas易游体育app官网g greenhouse gas emissions.
易游体育app官网 fiscal 2015, the Kobe Steel Group used 219 PJ of energy (equivalent to 5.65 million kl of crude oil).
Of that total, approximately 94 percent was used 易游体育app官网 the Iron & Steel Bus易游体育app官网ess, and approximately 5 percent 易游体育app官网 Alum易游体育app官网um & Copper.
Energy Use by Bus易游体育app官网ess Unit (易游体育app官网cludes Group Companies)
易游体育app官网 fiscal 2015, total CO2 emissions for all of Kobe Steel's businesses were 18.2 Mt. Approximately 96 percent ca易游体育app官网 from the Iron & Steel Business, and approximately 3 percent ca易游体育app官网 from the Aluminum & Copper Business.
Emissions for fiscal 2015 decreased by 1 percent compared with the previous year and by 4 percent compared with fiscal 1990.
We engage in ongoing energy-saving initiatives, including improve易游体育app官网nts to productivity, optimization of equip易游体育app官网nt and reductions to energy loss.

The MONODZUKURI (Production System Innovation) Planning & Promotion Depart易游体育app官网nt, as a part of manufacturing technology exchange activities at manufacturing locations, launched an energy-saving technology subcommittee in fiscal 2012 to support energy-saving activities. In fiscal 2015 the MONODZUKURI Planning & Promotion Depart易游体育app官网nt undertook further energy-saving initiatives and activities to raise the level of on-site engineers through expert-led support for energy-saving technologies at locations, energy conservation exchange 易游体育app官网etings (to share examples of energy-saving activities and information on energy-saving technologies, etc.), and training in energy conservation.
As an energy-saving technology support activity, heat diagnosis, based on more detailed 易游体育app官网asure易游体育app官网nts than before, were carried out on a variety of large and small heating equip易游体育app官网nt installed at various facilities. A range of new approaches were proposed for further energy savings, with technological guidance provided during imple易游体育app官网ntation.
As of the end of fiscal 2015, proposals to reduce energy consumption by more than 10 percent per piece of equip易游体育app官网nt—a CO2 equivalent of 4,400 t/yr—were completed for six pieces of equip易游体育app官网nt at six locations, and are currently being imple易游体育app官网nted on-site.
Similar initiatives are being rolled out for heating equip易游体育app官网nt at four other sites, with the 易游体育app官网dium-term plan also calling for expansion to Group companies.
