Anti-Global Warming Measures

Anti-global warming measures and energy conservation

In fiscal 2010, the Fujikura Group worked to improve its energy efficiency by 2% at its production bases and by 1.5% at its offices in Japan and overseas, and as a result its per-unit CO2 emissions decreased by 3.1%. Specifically, Group sales increased, but its total CO2 emissions remained on the same level as fiscal 2009 (as a result of a 2.3% increase overseas but a 4% decrease in Japan). In Japan, we restored our manufacturing system to its normal state soon after the Great East Japan Earthquake, thereby minimizing the drop in energy efficiency at our domestic manufacturing bases.

Relative to fiscal 2007, the Group's total CO2 emissions decreased by about 12% in fiscal 2010, but per-unit CO2 emissions increased by 11% due to decreased sales.

For fiscal 2011 to 2015, we will endeavor to reduce our total CO2 emissions by 17% from the fiscal 1990 level in Japan and set CO2 emissions reduction targets for our overseas bases by fiscal 2012, eventually to improve the energy efficiency of our manufacturing bases and offices annually by 3.5% and 1.5% respectively. In Japan, following the revision of the Act on the Rational Use of Energy in fiscal 2009, we are now required to manage our energy use not only by site but also for the entire company. We will start to visualize our energy use with the ECO-PASS environmental information collection system and share more information between our bases, including examples of energy conservation, while curbing our energy consumption through energy conservation diagnoses to be carried out jointly by our bases.

Reducing the use of fossil fuel by replacing air conditioning equipment

DDK Ltd. replaced the air conditioners in its factory and warehouse with ice thermal storage air conditioning systems and discontinued the use of heating boilers, thereby reducing the use of heavy oil. As a result, the company reduced its CO2 emissions by 47 tons per year.

CO2 Emissions

Investigation to identify the most eco-friendly conductor size

Fujikura began to examine how to reduce CO2 emissions by increasing the size of cable conductors in cooperation with the Japan Standards Association (JSA) and the Japanese Electric Wire & Cable Makers' Association in fiscal 2009. Subsequently at the Sakura Plant in fiscal 2010, we conducted a verification test using an actual distribution line as a model.

We implemented this initiative to help electricity users reduce power transmission losses on low-voltage cables from the receiving end to the individual load ends. Conventionally the thinnest conductors that can accept electric current flows have been selected to minimize the initial cost, because the initial cost increases as the conductor size increases. Nevertheless, the cost of electricity including power transmission losses (running cost) decreases as the conductor size increases. Based on this, we aim to reduce CO2 emissions from the long-term view by selecting the conductor size that helps minimize the total lifecycle cost (initial cost plus running cost). In the verification tests conducted using a low-voltage distribution line as a model, it was confirmed that CO2 emissions would be reduced by 4.2 tons for a 2.2% reduction in power transmission losses. We will pursue energy conservation and reductions in CO2 emissions based on this result.

Response to the power restrictions in the summer of 2011

Due to the Great East Japan Earthquake that took place on March 11, 2011, the amount of electricity supplied by the Tokyo Electric Power Company and Tohoku Electric Power Co., Inc. substantially decreased, and pursuant to Article 27 of the Electricity Business Act, the Japanese government asked large customers of the electric power companies to reduce their power use by 15% in principle from July 1. In response, the relevant Fujikura Group's bases introduced measures to run their manufacturing systems with limited power supplies, thereby making a bigger social contribution and reducing CO2 emissions by conserving energy.

Main measures

  • Work shifts on holidays and nighttime
  • Reviewing temperature settings for air conditioners
  • Reducing the power used for air conditioning by shading facilities from the light, including growing green plants to form a "green curtain"
  • Making use of nighttime electricity by adopting ice thermal storage air conditioning systems
  • Increasing the operating efficiency of elevators
  • Reducing standby power used by equipment

Turning off lights across the Fujikura Group

The Fujikura Group implemented its first "turning off lights" campaign on June 22 (summer solstice) and July 7 (Star Festival and also Cool Earth Day). On these two days, participants turned off lights at both their workplaces and homes at 7:00 p.m. to give a "small consideration" to the Earth. In this campaign, about 20 of Fujikura's bases including head office, plants, and sales offices participated. Also we asked 80 Group companies in Japan and overseas to participate in the campaign, and a lot of companies and employees participated in it. In this campaign, participants were encouraged to have quality time by communicating with their families and friends in addition to considering the global environment.

We tend to take the use of lights for granted, and the "turning off lights" campaign has reminded participants of the importance of lighting and of communicating with families and friends.
