Basic Stance

In light of the need to fight global warming, the pursuit of energy-saving activities is one of the UACJ Group’s most important management concerns. Accordingly, we are steadily taking action on this front, focusing on what we can do in the present.

Fiscal 2017 Results

Fiscal 2017, the fifth fiscal year following the merger that created UACJ, was the final year of the Mid-term Management Plan and by the end of the year we had nearly completed our efforts to optimize production by transferring the manufacturing of various products among our works. Domestic production declined slightly, but energy consumption increased marginally compared to the fiscal 2016 level. CO2 emissions declined slightly compared to fiscal 2016 results for the total and per-unit production (assuming a fixed emissions factor for electric power).

Main Initiatives in Production Processes

Switching to LNG as a Heat Source for Production Processes

LNG results in 30% lower CO2 emissions than does heavy oil to generate the same amount of heat. UACJ, therefore, is systematically switching to LNG to provide heat for its production processes.

As of fiscal 2017, LNG (including city gas) accounted for approximately 79% of fuel usage at UACJ’s four works, in terms of heat generated.

Energy Saving Subcommittee

At the UACJ Group, meetings of the Energy Saving Subcommittee are held on a regular basis. These meetings serve as opportunities for key participants - representatives of the facilities departments at multiple business locations - to share information, consider differences in facility performance, and hear case presentations, all to achieve further improvements in energy saving endeavors.

Examples of Energy-Saving Activities

The UACJ Group’s principal energy-saving activities for fiscal 2017 are given in the table below. In addition to those initiatives, we made adjustments to combustion facilities, updated compressors, replaced deteriorated insulation, applied insulating coatings to reduce heat losses, fixed steam and air leaks, and installed solar panels on plant roofs to save energy at business locations throughout the Group.

Examples of CO2 Emissions Reductions (New for fiscal 2017)

Business Location Theme CO2Emissions Reduction Impact
(t‐CO2/yr.)
All business locations Conversion to LED ceiling light fixtures 400
Nagoya Works Reduction of electricity consumption by updating electrical equipment for rolling facilities 400
Fukaya Works Reduction of DX gas usage in the annealing furnace 200
Nagoya Works Reduction of electricity usage by updating electric room air-conditioning facilities 200
Fukaya Works Reduction of the number of boilers used 200

Main Initiatives in Logistics

UACJ is working to save energy in its logistics processes. Considered a Specified Consignor (*2) under the Energy Saving Law (*1), UACJ has established the goal of a 1% improvement in the 5-year average amount of energy used per ton-kilometer of shipments and is taking steps toward achieving it.

In fiscal 2017, the impacts of measures such as loading factor improvements and use of ship transport reduced the amount of energy used for shipping, per unit of sales, to a level below that for fiscal 2016.

To address another concern, CO2 emissions, we and business partners in the same industry have been cooperating since 2001 to improve shipping efficiency by jointly transporting certain extruded aluminum products.

  • *1 Energy Saving Law:Under an ordinance established by the Ministry of Economy, Trade and Industry under the Act on the Rational Use of Energy, a consignor, who is in the position of requesting services from a freight carrier, is required to develop an energy-saving plan, and work to reduce energy consumption.
  • *2 Specified Consignor:
    A consignor whose annual shipments of its own freight equals or exceeds 30 million ton-kilometers

Main Initiatives in Offices

Energy-Saving Activities in Offices

UACJ’s offices are actively working to cut electricity usage by implementing the Japanese government’s “cool biz” and “super-cool biz” hot-weather measures, raising thermostats in the summer and lowering them in the winter, and systematically turning off lighting, electronic devices, and other electricity-consuming items when not in use.

Office-Based Environmental Protection Measures

As environmental protection initiatives, individual UACJ offices separate waste into paper and plastic, and recyclables into newsprint, copy paper, magazines, and cardboard.

For office supplies, items complying with the Law Concerning the Promotion of Procurement of Eco-Friendly Goods and Services by the State and Other Entities and eco-mark items are purchased to the extent possible.
