Respond to Climate Change

Introduction of renewable energy

The NTN Group is working to reduce CO₂ emissions (Scope 2) by installing power generation facilities for renewable energy at its business sites and purchasing carbon-free energy through PPAs^＊1.
In the fiscal year ended March 31, 2021, we generated 619,614 kWh /year in Japan and 12,158,778 kWh /year overseas, achieving CO₂ reductions of 236 tons-CO₂ /year in Japan and 6,393 tons-CO₂ /year overseas.^＊2

＊1 PPA (Power Purchase Agreement): A contract to install a solar power generation system owned by a third party power generation company on a roof, etc. and purchase the power from the system.

＊2 CO₂ emission reductions using the "Electricity emission factor based on market standards": 280 tons-CO₂/year in Japan; 8,184 tons-CO₂/year overseas.

Installed onsite solar power generation equipment

The NTN Group is promoting the installation of solar power generation equipment at its business sites through self-investment and PPAs.

■Introductory example in Japan

Kuwana Works signed our first PPA in Japan, with MUL Utility Innovation Company Limited, under which it installed a total of 900 solar panels on the roof of the east wing of its extra-large bearing plant. In April 2021, it started power generation, which is expected to generate 344,630 kWh/year and reduce CO₂ emissions by 131 tons-CO₂/year.^＊

■Overseas introductory example

Guangzhou NTN-Yulon Drivetrain Co., Ltd. (Guangzhou NTN, China) installed a total of 7,810 solar panels on its factory roof through a PPA. In September 2020, it started power generation, which is expected to generate 2,212,000 kWh/year and reduce CO₂ emissions by 1,265 tons-CO₂ /year.^＊

＊Greenhouse gas emissions reductions using the "Market-based electricity emission factors”: 147 tons-CO₂/year in Japan; 1,779 tons-CO₂/year overseas.

Initiatives for energy-saving

In order to reduce CO₂ emissions from production activities, the NTN Group has set reduction targets for each of its business sites, and continues diligently to implement activities such: as energy-saving measures for compressors, air conditioning, lighting, and other utility equipment; adding inverters to fixed-speed motors; measures against air leaks; and turning off non-operating equipment. In particular, we make use of the "Energy Conservation Warashibe Choja Budget," which is a budgetary framework limited to capital investment for CO₂ reduction that started in fiscal 2016. This is a unique initiative that allows us to use the energy costs reduced through energy conservation as a budget line for the following fiscal year, leading to voluntary CO₂ reduction activities through the creativity and ingenuity of each business site.

Reduction of CO₂ emissions in heat treatment processes

In order to reduce CO₂ emissions from heat treatment facilities, the NTN Group is switching to LPG^＊ and city gas as fuel, and is expanding the use of high-frequency heating equipment and electric furnaces with superior energy efficiency. Kuwana Works has recently introduced an electrically heated vacuum carburizing furnace. In the future, we will consider the use of ammonia and hydrogen, which do not emit CO₂.

Reducing CO₂ emissions in logistics

The NTN Group is working to reduce CO₂ emissions during product transportation by improving logistics efficiency. The main measures are shortening transportation distances by integrating distribution bases; increasing the loading ratio by expanding the use of module outer boxes; improving the efficiency of packaging operations by unifying distribution routes; and promoting the reuse and recycling of wooden pallets. In the fiscal year ended March 31, 2021, we achieved a reduction of CO₂ emissions from domestic product transportation of 10.9 thousand tons-CO₂ / year (compared with our target reduction of 12.7 thousand tons-CO₂/year), and CO₂ emissions intensity was 0.0369 tons-CO₂ / million yen (compared with our target of 0.0345 tons-CO₂ /million yen). While we achieved our CO₂ emissions target, we did not achieve our CO₂ emissions intensity target.

Validation opinion by a third party on CO₂ emissions

A third-party verification of CO₂ emissions for the fiscal year ended March 31, 2021 was conducted, confirming that there were no issues with the method for calculating CO₂ emissions.

Development of a product line that responds to the intensification of natural disasters
Ｎ³ N-cube, NTN Green Power Station

NTN Group has developed the NTN Green Power Station (”GPS”) as an independent power supply device that generates power using a hybrid of wind and solar power, and the N³ N-Cube (”N3”), which contains a power generation device using three types of natural energy (wind, hydro, and solar) and storage batteries, and can be moved to the required location to generate and supply power in a short time.
Last year, GPS was adopted by Sakurai City, Nara Prefecture, as a "large-scale disaster power supply station" for a designated evacuation site with a large parking lot. Evacuation using private vehicles has attracted attention as a measure during the COVID-19 pandemic, as it offers a way to disperse evacuees to avoid shelters becoming crowded. The GPS will be used to provide evacuees with light at night and to charge cell phones and smartphones. At ICSA INDUSTRIA CUSCINETTI S.P.A., our business site in Italy, GPS is used to illuminate the entrance to the business site, which also contributes to raising environmental awareness among employees. In addition, N3 has been adopted as a multipurpose warehouse with independent power supply function in the Hoshimigaoka Disaster Prevention Base Facility built by Kuwana City, Mie Prefecture. The 12-foot N3 is a stockpile warehouse that can store medicines and relief supplies at a controlled temperature by operating the air conditioner 24 hours a day, and the 10-foot N3 can be separated and moved to the disaster area to be used as an emergency power source in the event of a disaster. The 10-foot N3 will be separated and moved to the disaster area in the event of a disaster and operated as an emergency power source.
In March 2021, the N3 was used in Kuwana City's disaster drill to deploy air tents for emergency aid stations.
The NTN Group will continue to promote the social implementation of natural energy products that are carbon-free and that support disaster mitigation.
