Environment

Recognizing that environmental issues are the most critical issue common to all humankind, our group operates by the following policy in all of our corporate activities to contribute to realizing a society where environmental conservation and economic development are in harmony.

• ①We strive to preserve and improve the environment by focusing on energy-saving, resource-saving, and recycling.
• ②We comply with applicable laws, regulations, and other requirements.
• ③We strive to prevent accidents, disasters, and environmental pollution.
• ④We strive to improve our environmental management system continuously.

Greenhouse Gas（GHG） Emissions Reduction

The main types of energy used in our group’s business activities include electricity required for producing our core products, industrial gases, and vehicle fuel used for sales and delivery services. Electricity consumption accounts for 79.3% of our total CO₂ emissions. Electricity consumption at the Tagajo Plant accounts for 73.1% of total CO₂ emissions, and we are working to reduce electricity consumption by improving electricity consumption rates through measures such as the adoption of energy-saving equipment. Additionally, since FY 2022, the organizational scope of our data collection on energy usage is aligned with the Ministry of the Environment’s guidelines^*1, and we calculate the group’s Scope 1 and Scope 2 emissions. In the future, to reduce CO₂ emissions systematically, we will adopt more energy-saving equipment at production plants, switch to LED lighting in offices, and promote the use of hybrid and EV vehicles for sales and security services.

  *2

  • ・ Scope 1：Direct emissions from fuel usage and production processes within the company.
  • ・ Scope 2：Indirect emissions from the use of electricity and other energy purchased by the company.
  • ・ The CO₂ emissions for Scope 1 and 2 are calculated using the values from the Ministry of the Environment’s “Calculation Methods and Emission Factors List under the GHG Emissions Accounting, Reporting, and Disclosure System.”

Emissions of Environmentally Hazardous Substances

We strive to manage and reduce emissions of substances emitted during the painting process of high-pressure gas containers subject to the PRTR law^*1 and VOCs^*2 targeted by the Air Pollution Control Law, as well as a freon (HCFC-22^*3) used in the refrigeration equipment at the Tagajo Plant that is subject to the Ozone Layer Protection Law.

*1 PRTR Law : Act on the Assessment of Releases of Specified Chemical Substances in the Environment and the Promotion of Management Improvement.
*2 VOC : Volatile Organic Compounds.
*3 HCFC-22 : Amount replenished during refrigeration equipment maintenance.

Efforts to Reduce Industrial Waste

Our group promotes the reuse of waste generated from business activities and strives to reduce waste generation by purchasing and using long-life products. We also manage the total amount of industrial waste generated across the group, survey the recycling rate of each disposal contractor, and work on promoting recycling activities.

Our group produces and supplies customers with industrial and medical gases such as oxygen, nitrogen, argon, hydrogen, and acetylene, called separate gases. In our gas production and supply activities, we recognize that ensuring quality and stable supply is our mission, and we strive to provide quality assurance by strengthening our analytical technologies and shipment control systems and conducting regular quality assurance audits at each of our plants.
Furthermore, to improve environmental performance and customer satisfaction, we have obtained the ISO 14001 certification for environmental management systems and the ISO 9001 certification for quality management systems at the Tagajo Plant and Toho Sakata Suiso Co., Ltd., a group company.
