Initiatives toward building a low-carbon society

Fiscal 2017 targets and results

Based on the Aichi 2020 Environmental Action Plan, we pursued reductions in carbon dioxide to achieve the targets of the Japan Iron and Steel Federation’s Low-carbon Society Plan (Phase 1).
We set our internal targets at even higher levels and took action, but we were unable to avoid the negative effects of increased production, and we did not achieve those targets.

Factors behind changes since last fiscal year

Positive improvements

1. Improved insulation on rolling line furnace 1,000 t-CO2/year
2. Less carburizing material due to appropriate use of scrap 4,900 t-CO2/year
Total 5,900 t-CO2/year

Negative factors

1. Increased emissions due to increased production 39,100 t-CO2/year
Total 39,100 t-CO2/year

Energy saving in offices

We conducted the following activities during fiscal 2017. Going forward, we will investigate, analyze, and follow energy efficiency at the new administration building with a view to making further improvements.

  1. Summer/winter measures to reduce electricity consumption
    • Promoting Cool Biz activities (preset temperature 28°C)
    • Promoting Warm Biz activities (preset temperature 19°C)
    • Installation of various energy-saving equipment at new administration building, and calls for energy-saving activities
  2. Other
    • Conversion from fluorescent to LED lighting at Technology Center No. 1 and No. 2 offices and at the Forging Office

Energy efficiency through logistics optimization

In accordance with the Energy Saving Act revised in April 2006, we have been working on efficient environmentally-friendly logistics optimization activities after understanding the flow of distribution and reviewing issues.

Specifically, we are visualizing the flow and quantities of products after shipment, our Steel Company is promoting logistics reform from Promoting logistics reform and modal shift*, and our Forging Company is doing the same from the perspective of loading efficiency improvements.

From fiscal 2006 to 2017, we achieved a 16% reduction in CO2 emissions per unit from logistics.

  • * Modal shift Changing truck transport to rail and sea transport with low-environmental impacts
