Global Warming Prevention

Improvements in CO2 Emission Intensity

In the 2019 fiscal year, we improved our CO2 emissions intensity to 78% at domestic offices and to 67% at overseas plants compared to the 2014 fiscal year.
We’re striving to improve efficiency by introducing high efficiency lighting and air conditioning equipment; changing and repairing aging pipes; reducing operating duration of production facilities; and consolidating workplaces. We will strive to further reduce CO2 emissions and improve environmental performance.

Goals and Results of Our Activities

We’re seeking to improve the oil equivalent energy/production (intensity) at domestic offices, and to improve electricity/production (intensity) at the overseas plants. The goals and results are as shown below.

  • Reduction of Oil Equivalent Energy/Production (Japan)

    At offices in Japan, we’re committed to improving oil equivalent energy/production and striving to achieve 22% reductions from fiscal year 2016 by fiscal year 2030.
    In fiscal year 2019, we strove to improve on efficiency by consolidating workplaces and facilities; introducing high efficiency equipment; continuously reducing losses, including air leakage losses; and reviewing the work shifts of the manufacturing units based on the production required. Despite these efforts, the results included an increase of 2% from the previous year because the fixed energy ratio in the gross domestic energy was increased due to production transfer to overseas, and due to the coronavirus crisis.
    In fiscal year 2020, we’re committed to optimizing management indicators in response to changes in production sites and energy composition and examining improvements by focusing on fixed energy.

  • Reduction of Electricity/Production (Overseas Plants)

    At plants outside Japan, we’re committed to reducing electricity/production and striving to achieve 14% improvements from fiscal year 2016 by fiscal year 2030.
    In fiscal year 2019, we took various actions to improve profitability, including introducing high efficiency lighting and air conditioning equipment, monitoring departments via IoT, continuously improving work efficiency, and reviewing production bases. As a result, we achieved 23% reductions from fiscal year 2016. In fiscal year 2020, we plan to promote activities through further rationalization.
