Tsubakimoto Custom Chain, Tsubakimoto Sprocket, Tsubakimoto Bulk Systems, Tsubakimoto Mayfran, Tsubakimoto Iron Casting, and Tsubaki Yamakyu Chain
Implemented period:
April 1, 2024 to March 31, 2025
EcoFactory Certification System
The Group recognizes that responding to the threat of climate change (by reducing CO2 emissions), acknowledged as an urgent environmental challenge, is a sufficient condition for an environmentally advanced company. It also recognizes that waste reduction, appropriate management of hazardous chemical substances, and other resource recycling efforts—along with the pursuit of greater harmony with nature through greening and water conservation—are necessary conditions for an environmentally advanced company.
Against this backdrop, in FY 2018 we established the EcoFactory Certification System for our business sites in Japan. This initiative encompasses management indicators and milestones for each of the three theme areas—climate change, resource recycling, and maintaining harmony with nature—with the goal of steadily achieving our long-term environmental targets for the year 2030. Upon obtaining SBT certification in June 2023, we changed the baseline year for our climate change management indicators from FY 2013 to FY 2021. We also began measuring by intensity criteria instead of total emissions volume so that we can more accurately evaluate the results of our autonomous measures to reduce emissions.
