Initiatives Towards a Decarbonized Society

Policy

The Sanwa Group contributes to the realization of a sustainable, affluent society through the emission reduction of CO2 and other greenhouse gases in order to appropriately address climate change risks.

CO2 Emission Reduction Targets and Trends

The Sanwa Group recognizes the impact of our business operations on the global environment and the importance of mitigating this impact. In May 2022 we established new environmental targets and a new policy for achieving carbon neutrality.

CO2 Emission Reduction Trends (Japan, Global)

※In December 2022, Japan’s figures from FY2019 to FY2021 updated following a change in calculation method in line with a third-party verification. Adjusted emission factors have been used since FY2019.

Initiatives to Reduce Energy Consumption and CO2 Emission

Sanwa Shutter Corporation and other domestic group companies have established and are operating an environmental management system based on ISO 14001 guidelines, and we are working to reduce our impact on climate change by setting targets for energy reduction and efficiency, as well as targets for lower CO2 emissions.

※Figures from FY2019 to FY2021 have been updated following a change in calculation method in line with a third-party verification. Adjusted emission factors have been used since FY2019.
※The Japan Management Association GHG Certification Center (JMACC) has provided third-party verification of the values for Sanwa Shutter Corporation’s CO2 emissions from FY2021.
※From the fiscal year 2023, it includes 82.16t-CO2 of heat and steam supply received by the Shinjuku Mitsui Building from the Shinjuku District Heating and Cooling Center.

To achieve our CO2 reduction targets, Sanwa Shutter Corporation calculates and reduces Scope 1 emissions (direct emissions from business activities) and Scope 2 emissions (indirect emissions from the manufacturing stage of energy used in business activities) at production sites (plants) and nonproduction sites (offices).
At our plants, initiatives for reducing Scope 1 emissions include upgrading to energy-efficient equipment and reducing operating hours by improving productivity. Scope 2 emission reductions include using renewable energy, switching to LED lighting, as well as using monitoring systems to visualize demand and consumption of electricity to reduce energy use.
In March 2021, Sanwa Shutter's Ota Door Plant switched from using boilers for drying paint to using electric fan heaters, reducing kerosene consumption by more than half.
In December 2021, solar power generation system was installed on the roof of the logistics building at the Ota Door Plant. The total area of the panels is approximately 3,500 m2, and they reduced CO2 emissions by approximately 73 t-CO2 in FY 2021, 280 t-CO2 in FY 2022, and 329 t-CO2 in FY 2023.
In addition, in July 2023, solar power generation system was installed on the premises of the Sanwa Shutter’s Kyushu Plant. The total area of the panels is approximately 7,000 m2, which contributed to approximately 349 fewer t-CO2 of CO2 emissions in FY 2023.
In our offices, in addition to switching to LED lighting and updating air conditioning systems, the company is also switching to eco-friendly sales vehicles to reduce gasoline consumption.

As a result, despite of the increase in electricity and fuel use at the plant due to increased shipments, Sanwa Shutter Corporation’s CO2 emissions (Scope 1 + 2) in FY 2023 decreased by 0.9% from the previous year and 7.4% from FY 2019 (the base year). Overall domestic CO2 emissions decreased by 1.4% from the previous year.

Initiatives to Reduce Energy Consumption in Logistics (Sanwa Shutter Corporation)

Adhering to the Law Concerning the Rational Use of Energy, Sanwa Shutter Corporation is working to achieve a 1% reduction in energy consumption intensity of production per year and a 1% average improvement in energy consumption intensity of production per year over five years. To reach these goals, the Company is implementing multiproduct mixed delivery using depots (small distribution centers) in the Tokyo metropolitan area, Sendai, and Shikoku. In addition, in July 2020, the Company introduced a vehicle dispatch and warehouse management system to improve the efficiency of vehicle dispatching and promoted better warehouse entry/exit and inventory management. These moves helped improve the loading ratio and reduced the number of vehicles sent out.

Initiatives to Reduce Energy Consumption and CO2 Emission (North America)

In FY 2021, ODC began calculating CO2 emissions (Scope 1 + 2) from ODC headquarters and all plants. The results for FY 2023 were 25,374 t-CO2 (Scope1: 7,153 t-CO2, Scope2: 18,222 t-CO2), representing an 11.3% decrease from the previous year.
Pensacola plant of ODC uses computer-controlled lighting and an energy-efficient air-conditioning system in order to reduce unnecessary electricity use.
Additionally, the Centralia plant has switched to energy-efficient lighting and Won-Door has not only changed the office area lighting to LED but also upgraded the HVAC systems to more energy-efficient models, striving to reduce energy consumption.

Initiatives to Reduce Energy Consumption and CO2 Emission (Europe)

In FY 2021, NF Group began calculating CO2 emissions (Scope 1 + 2) from NF GmbH headquarters and all plants. The results for FY 2023 were 17,117 t-CO2 (Scope1: 11,307 t-CO2, Scope2: 5,809 t-CO2), representing a 16.9% decrease from the previous year.
In the NF Group, Riexinger plant in Germany, NF Door plant in Poland, Robust AB's plant in Sweden, and Vertriebs sales company in Germany have acquired ISO 14001 certification and are working to reduce energy consumption, and in the Riexinger, Machcoul, and Bavilliers plants, we have implemented energy consumption monitoring systems to improve energy efficiency. To help reduce CO2 emissions, solar power generation systems (panels) were installed in the Luton Plant in the UK and the Schievano Plant in Italy in April 2023 as well as the Alsal Plant in Spain in May 2023.

In FY 2022, Asian subsidiaries began calculating CO2 emissions (Scope 1 + 2) from Asian subsidiaries headquarters and all plants. The results for FY FY 2023 were 3,134 t-CO2 (Scope1: 527 t-CO2, Scope2: 2,607 t-CO2), representing a 24.5% increase from the previous year.

We have introduced solar power generation facilities at Shanghai Baochan-Sanwa Door since May 2023, contributing to the reduction of CO2 emissions and electricity costs. Additionally, solar power generation facilities were installed at Sanwa NF Changshu, and operations commenced in June 2024. The total panel area is 6,680 m2, with an expected annual reduction of approximately 1,397 t of CO2 emissions.

Scope 3 Initiatives

To achieve a carbon neutral society, it is necessary to reduce CO2 emissions not only within the Company but also throughout the entire supply chain. For the first step to reduce overall CO2 emissions in the supply chain, we began calculating the previous year's results of Scope 3 emissions (Categories 1, 3, and 4) from the FY 2023. In the FY 2024, we will newly conduct calculations for Categories 2, 5, 6, 7, 10, and 11. As a manufacturer, we have obtained third-party verification for Category 11 (use of sold products) = the CO2 emissions resulting from the use of products sold to customers, which is closely related to us.
