CSR activities in FY2017
Resource protection
As well as continuing ongoing efforts to reduce water consumption and improve water consumption intensity, the NTN Group responded to the recent rise in concern over water risks by using Aqueduct*1 to assess these risks for individual business sites in 2017. Current and forecast quantity and quality were assessed. We will continue working to reduce water consumption and recycle water, with activities tailored to water risks and production volumes at each business site.
Water stress (2030 projection) and current water consumption
*1 Aqueduct: A tool released by the World Resources Institute (WRI) that provides free maps and information showing global water risks.
*2 Includes 4 additional business sites (NDB, NTPT, NNMI Chennai and Nanjing NTN).
Combating water risks in India
Using Aqueduct to assess water risks, we found that the Bawal plant and Chennai plant of NTN NEI Manufacturing India had the highest water risks among all the NTN business sites worldwide. The Chennai plant experiences water shortages in summer, and buys water shipped by tanker trucks as needed to handle water intake restrictions and tap water supply cuts. Since tap water quality is poor, the plant combats water risks by making planned purchases of RO*1 and DMF*2 treated water. As a way to reduce water consumption, the plant has installed fixed-quantity shutoff valves on all water taps.

Reducing Water Consumption
Our Japan and overseas business sites both managed to meet their water consumption intensity targets in the fiscal year ended March 31, 2018. The Japan target was a reduction of 16.8% relative to the fiscal year ended March 31, 2011. The overseas target was a reduction of 1.2% relative to the fiscal year ended March 31, 2015. We will continue to reduce our water consumption and water consumption intensity in the fiscal year ending March 31, 2019.

Reducing Waste and Improving Recycling Rates
We worked on reducing our waste intensity in the fiscal year ended March 31, 2018, and our business sites in Japan achieved their target of a 1.6% reduction relative to the fiscal year ended March 31, 2011. We will continue to work on reducing waste in the fiscal year ending March 31, 2019 by reducing the waste intensity of our business sites in Japan and improving our recycling rates. We are targeting a waste intensity reduction of 3.8% relative to the fiscal year ended March 31, 2011, and minimum recycling rates of 99.8% (Japan) and 97% (overseas).
