Environmental Conservation
Input＆Output（FY2025 performance of JSP Corporation)
Reduction of CO2 Emissions (JSP Corporation)
JSP Corporation's CO2 emissions in FY2025 decreased by approximately 2.2% from the previous fiscal year and by 27.6% from FY2013. The main reasons for the improvement are the aggregation of plant operating days, effective use of waste heat, and our efforts toward reducing air leaks and heat-radiation loss in the plants.
In addition to reducing our own CO2 emissions, we are also contributing to the reduction of CO2 emissions in society by using our foamed plastic products to improve the fuel efficiency of automobiles and the heating and cooling efficiency of homes.
Reduction of Energy Consumption (JSP Corporation)
In FY2025, JSP Corporation's energy consumption decreased by approximately 1% compared to the previous fiscal year.
However energy consumption per unit of production calculated using production volume as the denominator worsened by approximately 2.4% compared to the previous fiscal year.
We will continue to promote and maintain energy-saving initiatives at each of our facilities so that we can achieve year-over-year improvements starting in fiscal year 2026.
Challenge for Modal shift (JSP Corporation)
With the aim of environmental responsiveness, energy efficiency, and transportation stability in logistics, JSP Corporation is implementing modal shift to rail and ferry transportation, which emit less CO2 than truck transportation.
Modal shift is also effective for safe and stable supply in the event of road disruptions due to natural disasters. In addition, it offers an effective solution to issues such as compliance with two logistics-related laws and long working hours in long-distance transport. Moreover, it has a strong presence as a secondary or tertiary means of transportation. We will continue to actively engage in modal shift initiatives.
Reduction of Water Usage(JSP Corporation)
JSP Corporation carries out production activities using a water circulation system that recycles water without throwing it away in the manufacturing process. In FY2025, water consumption was 901,000 tons.
Reduction of Landfill Amounts
In JSP Corporationʼs mid-term Responsible Care plan, we set a target for the final landfill amounts in FY2025 of “continuing to reduce landfill amounts through enhanced separation” and implemented systematic reduction activities at each business site.
In FY2025, there was a slight decrease compared to FY2024.
