Environmental Accounting

In order to protect the environment in an efficient manner, we quantify our investments and development costs and benefits at our business locations in Japan using classifications indicated in guidelines prepared by Japan’s Ministry of the Environment. We are engaged in a major effort to develop Sustainable Products with an eye on global environmental conservation, and are proactively working to seize business opportunities that will contribute to an improved social environment. In addition, to reduce CO2 emissions at our business locations, we are strengthening our initiatives targeting global environmental conservation by increasing the eco-friendliness of our various facilities.
The Tsubaki Group uses its environmental accounting system to analyze the cost of environmental conservation and the economic and ecological benefits obtained through environmental conservation activities. This information will be subject to disclosure and will also be utilized in future activities.

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 locations 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. Following acquisition of SBT certification in June 2023, the management indicators for climate change were changed from comparisons with FY 2013 to comparisons with FY 2021. In addition, to more clearly evaluate the reduction results from voluntary efforts, the standard was changed from total emissions to intensity.
