Initiatives for building a low-carbon society

Fiscal 2020 targets and results

Based on the “Aichi 2020 Environmental Action Plan,” we pursued reductions in CO2 to achieve the targets of the Japan Iron and Steel Federation’s “Commitment to a Low Carbon Society” (Phase 1). We reduced total CO2 emissions through a combination of reduced production and improved operations.

Factors behind changes since last fiscal year

Improvement factors

1. Reduced energy consumption
due to reduced production
59,500 t-CO2/year
2. Reduced energy consumption
due to improved operations
through optimization of
steel making materials
9,900 t-CO2/year
Total 69,400 t-CO2/year

Hindrance factors

1. Increased energy consumption
due to reduced production
and the resulting drop in
steel making efficiency, etc.
7,500 t-CO2/year
2. Increased energy consumption
due to reduced production
and the resulting drop in
rolling operation efficiency
1,600 t-CO2/year
Total 9,100 t-CO2/year

Energy saving in offices

We conducted the following activities during fiscal 2020. Going forward, we intend to understand, analyze, and carry out follow-ups on the energy-saving effects of the head office building, and make 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)
    • Reviewing the relationship between teleworking and the usage of conference rooms at the head office building, and limiting the times during which air conditioning and lighting are turned on
    • Using green walls at stores to save energy in summer
  2. Other
    • Encouragement from the eco life promotion team to save electricity

Energy saving 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.

More specifically, we are visualizing off-premise logistics routes and volumes, and promoting logistics improvements from the perspective of streamlining routes, modal shifts (from land transport to sea transport), and improving loading rates.

From fiscal 2006 to 2020, we achieved a 14% reduction in CO2 emissions per unit from logistics.

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