CSR activities in FY2019
In-house technologies for measures against climate change
NTN develops business activities based on our corporate philosophy "We shall contribute to international society through creating new technologies and developing new products," and the paragraph 1 of the NTN Environment
Policy "Technologies to help prevent global warming."
As bearings and driveshafts, which are main products of NTN, contribute to the reduction of energy loss in final goods of our customers equipped with them (hereinafter referred as
"final goods"), all of these products can be considered as environmentally friendly products. They include products which are already commonly used in society because of the achievement of predecessors, as well as those with environmental
contributions further enhanced by NTN’s engineering and development capabilities.
NTN continues unwavering efforts to realize its corporate philosophy by developing and providing higher-grade products that contribute to the environment
while classifying the products according to environmental contribution levels based on our standards.
Definition of In-house technologies for measures against climate change
(1)Classification and grades of NTN products and their definition
(2)Calculation methods for environmental factors and eco-efficiency
To quantify products'environmental friendliness, NTN adopted environmental factors and eco-efficiency that are defined in the formula1and2as follows.
＊1 D-eco product
＊2 Values are quantified by using the QFD method (including CO2 reduction contribution as final goods)
＊3 From the perspective of evaluating
contribution toward measures against climate change, environmental impact are calculated as CO2 emissions generated throughout the process of raw materials mining to production (used the LCI calculation tool by the Japan Auto
Parts Industries Association)
Trend in achievements and forecasts
(1) Environment-contributing product ratio of driveshaft and hub bearings
As in the previous year, driveshafts and hub bearings, our core products that account for about 70% of our net sales, were classified according to the criteria for environmetnt-contributing products. The sales ratio of S-B-eco grade environment-contributing products, which are achievements of NTN’s development efforts in recent years, has reached 42.2% in the fiscal year ended March 31, 2020.

(2) Contribution to CO2 reduction from driveshafts and hub bearings
NTN calculates the amount of CO2 emissions that can be reduced by the contribution of S to C-eco products throughout the assumed life period of final goods in comparison to the amount of CO2
emissions in case D-eco products are continued to be used in final goods instead. Such amount is defined as “Contribution to CO2 reduction” of the year the Company's products are sold.
The contribution to CO2 reduction from environment-contributing products of the Company for the fiscal year ended March 31, 2020 was approximately 1,490,000 tons (equivalent to approximately 640,000 thousands litters of
gasoline).

Contribution to CO2 reduction from green energy products
As one of our new businesses, we are conducting a green energy a business and developing products that can utilize renewable energy.
Green energy products are environment-contributing products that generate electricity using
clean-energy sources such as wind, water, and solar power that exist everywhere to reduce CO2 emissions. They are expected to supply as an independent power source for the mini-grid network, which can provide efficient power
supply in non-electrified areas of the world, and as a regional power source that can utilize unused energy in the region.
In addition, they are used as a power source in the event of a power failure at the time of a disaster to provide
safety and security to local communities. (For details, see page 51.) Contribution to CO2 reduction from green energy products is shown in the table.
