NSK Publishes Japanese Bearing Industry’s First Carbon Footprint of Products (CFP) Assessment for Reconditionable Large-Size Tapered Roller Bearings with High Load Capacity
NSK Ltd. (NSK; Headquarters: Tokyo; President & CEO: Akitoshi Ichii) has published a CFP Assessment Report summarizing the company’s self-assessed carbon footprint of products for its reconditionable large-size tapered roller bearings developed for mining equipment. NSK published the report as part of its efforts to help build a decarbonized society. This is the first CFP assessment report for a reconditionable bearing to be published in the Japanese bearing industry*1.

1. Background and Importance of CFP Disclosure
CFP is a quantitative indicator that shows greenhouse gas emissions per product. With the global push toward a decarbonized society, policies focusing on CFP are being promoted worldwide. In Japan as well, interest in CFP disclosure is growing, as evidenced by the Ministry of the Environment’s publication Guide to Carbon Footprint Indications in February 2025. CFP is calculated based on CO2 emissions throughout the entire product lifecycle; however, since values vary depending on calculation conditions, the transparent disclosure of such information is essential.
2. NSK’s CFP Assessment Report Initiatives
NSK has been working to reduce maintenance costs and CO₂ emissions for mining equipment, and in March 2025, the company developed the industry’s first*² high-load capacity large-size tapered roller bearing designed for easy disassembly and reconditioning (reuse through restoration).
This CFP Assessment Report aims to clearly communicate the calculation metrics for CO₂ emissions across the entire lifecycle of this product.
