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 2015 Results
In fiscal 2015, the third fiscal year following the merger that created UACJ, we moved forward with production optimization, in line with the Mid-term Management Plan. Production was streamlined by transferring the manufacturing of various products among our works, and this, together with a decline in domestic production volume, resulted in an overall year-on-year decline in energy usage. CO2 emissions also declined on an overall basis, but rose per unit of production, compared to the previous fiscal year. (Assuming a fixed emissions factor for electric power.)
UACJ Group CO2Emissions
- *1 The CO2 emissions factor is the one used for electricity generation, 0.378kg-CO2/kWh.
- *2 Measurement Scope: UACJ (Nagoya, Fukui, Fukaya, Nikko), UACJ Color Aluminum Corporation, UACJ Extrusion Nagoya Corporation (Nagoya, Anjo), UACJ Extrusion Oyama Corporation, UACJ Extrusion Gunma Corporation, UACJ Extrusion Shiga Corporation, UACJ Foil Corporation (Isezaki,Shiga,Nogi), UACJ Foundry & Forging Corporation, UACJ Copper Tube Corporation
- * Figures for fiscal 2013 are totals of the sums for the two UACJ predecessors for the first half (April 1 to September 30, 2013) and UACJ for the second half (October 1, 2013 to March 31, 2014).
Main Initiatives in Production Processes
Switching to LNG as a Heat Source for Production Processes
When heavy oil and LNG are used to generate equal amounts of heat, the amount of CO2 emitted from the use of LNG is 30% lower than that from the use of heavy oil. UACJ, therefore, is systematically switching to LNG to provide heat for its production processes.
As of fiscal 2015, LNG (including city gas) accounted for approximately 76% of fuel usage at UACJ’s four works, in terms of heat generated.
Energy Saving Subcommittee
UACJ regularly holds Energy Saving Subcommittee Meetings. These meetings, which are joined mainly by facilities departments, have participants from multiple business locations. Information is shared among these various locations and all participants are informed of certain case examples in an effort to achieve significant improvements in energy saving.
Examples of Energy-Saving Activities
The UACJ Group’s principal energy-saving activities for fiscal 2015 are given in the table below. In addition, actions such as updating of chillers and air-conditioning systems, adoption of inverter technology for heating furnace fans, fixing of steam and air leaks, and reduction of energy usage by disengaging power and reducing heat losses during production line down periods were taken at business locations throughout the Group. As in fiscal 2013, the transition to LEDs for overhead lighting continued.

UACJ Copper Tube Corporation
Optimization of cooling tower pump and fan operation
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 2015, lower production volume had a major impact resulting in a slight year-on-year increase in energy used per ton-kilometer of shipments.
In addition, since 2001, we or our predecessor companies have been engaged in joint logistics with business partners in the same industry for the transport of extruded aluminum products. These relationships have contributed to CO2 reductions by making shipping more efficient.
Looking forward, we aim to achieve additional improvements to realize the benefits of the merger even in areas such as logistics rationalization.
- *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
Amount of Energy Used for Shipping, per Unit of Sales

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.
