Trends in Volume of CO2 Emissions

NGK SPARK PLUG Group set its per-unit CO2 emissions reduction target in its Global Eco Vision 2020 as part of efforts to reduce greenhouse gas emissions, a factor contributing to climate change. To attain this target, we are striving to diminish our energy usage.

Under the Global Eco Vision 2020, we aimed to reduce CO2 emissions per unit of production for group companies in Japan (with integrated certification) by 15% from the FY2015 level, but with the result of a 6.1% reduction in FY2020, we did not achieve this target. This was due to production adjustments in the first half of FY2020 in response to the spread of COVID-19, which resulted in a deterioration of the unit requirements. On the other hand, in the second half of FY2020, when production began to recover, CO2 emissions per unit of production recovered to the pre-COVID-19 level, thereby confirming the effectiveness of our energy-saving measures to date.

In response to climate change, Eco Vision 2030 was launched in fiscal 2021, setting a target of reducing group CO2 emissions by 30% from the FY2018 level by 2030. We will further reduce CO2 emissions to achieve carbon neutrality by 2050.

Support for the TCFD Recommendations

In July 2020, NGK SPARK PLUG Group announced its support for the Task Force on Climate-related Financial Disclosures (TCFD) recommendations.
We will examine the impact of climate change on our Group’s business, strategies and finance within the company-wide risk management framework based on TCFD Recommendations, and these topics will be discussed at the Risk Management Committee and the CSR and Sustainability Committee attended by the entire board of directors. We will also promote voluntary and proactive disclosure of information in accordance with the recommendations.

Energy Conservation during Transportation

As a Specified Consigner designated under the Act on the Rational Use of Energy, we endeavor to reduce CO2 emissions during transportation, proceeding with reduction in shipping distance by reorganizing/integrating plants, and reconsidering the waste-disposal service vendor.
In fiscal 2020, our energy usage basic unit was 1.05 kL/100 million yen, which is almost as same as the previous fiscal year.

Energy Conservation in Office

We implement daily energy-saving measures in our workplaces, including turning off lights and computers during breaks and keeping office air conditioning at moderate levels, 28ºC in summer and 20ºC in winter, to which we adjust by dressing lightly or adding layers of clothing in addition to setting our regular ventilating standard at offices by reviewing the amount of ventilation.
We are also creating green curtains and thermally insulating the outdoor units of air conditioners to reduce power consumption for air conditioning in the summer. And by consolidating workplaces, where telecommuting is increasing and fewer people are coming to the office, we make efficient use of air conditioning and lighting.

Use of Renewable Energy

We promote the use of natural energy.
We installed three solar power generation units and one solar water heater at our Headquarters Factory. The Komaki Plant has a solar power generation unit that can generate a maximum of 107 kW of electricity.
Overseas, solar power generation units were installed into NGK Spark Plugs (India) PVT. LTD. with a maximum power generation capacity of 60 kW.
In fiscal 2020, we generated a total of 290,000 kWh sourced from natural energy in both domestic and overseas companies, which is equivalent to reduction of 138 tons of CO2.
