NSK Initiative on CO2 Emissions Reduction

Since 1999, our plants have been focused on the reduction of CO2 emissions from our own manufacturing facilities in addition to producing products to minimize energy consumption. Consistently we have exceeded a year-over year target of 1% CO2 reduction per production unit, and have also reduced the absolute CO2 emission levels, independent of production levels. These achievements are made through investment in advanced environmentally friendly facilities and through a global initiative on reduction of waste.

Find out more about bearings and our positive impact on the environment by visiting the World Bearing Association website.



Within the NSK Group Environmental Policy, it is required that all manufacturing sites obtain ISO14001 certification within 5 years of commencing operation. This policy has been consistently met and at present NSK has 47 manufacturing plants that have achieved ISO14001 certification.

Copies of the certificates can be downloaded from the Downloads section.
