Environmental Conservation
Input ＆Output（FY2024 performance of JSP Corporation)
Reduction of CO2 Emissions (JSP Corporation)
JSP Corporation's CO2 emissions in FY2024 decreased by approximately 0.8% from the previous fiscal year and by 26.7% 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 FY2024, JSP Corporation’s energy consumption decreased by approximately 5% from the previous year due to energy conservation activities at each business site. In addition, energy consumption intensity, using production volume as the denominator, also decreased by approximately 0.1% from the previous year. It has improved for three consecutive years. We will promote and continue energy conservation activities at each business site in FY2025 and beyond.
- * Contribution ratio method: Energy consumption intensity is calculated for each product group, and the ratio of energy consumption intensity of the entire businesses to that of the previous year is calculated in proportion to the ratio of the product group.
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 FY2024, water consumption was 914,000 tons.
Reduction of Landfill Amounts
In JSP Corporationʼs mid-term Responsible Care plan, we set a target for the final landfill amounts in FY2024 of “continuing to reduce landfill amounts through enhanced separation” and implemented systematic reduction activities at each business site. As a result, we were able to significantly decrease the amount compared to FY2023.
