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. In addition, under the Medium-Term Management Plan 2027, we announced our CO2 emissions reduction target for fiscal year 2027.

CO2 Emission Reduction Trends (Japan, Global)

Trends in CO2 emissions (domestic and overseas)
  • 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 in Japan 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 Sustainability Center (JMASusC) has provided third-party verification of the values for Sanwa Shutter Corporation's CO2 emissions from FY2021
  • From the fiscal year 2023, it includes 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.
We have also been promoting the installation of solar generation power systems. Solar panels were installed on the roof of the logistics building at the Ota Door Plant in December 2021, on the premises of the Kyushu Plant in July 2023, and on the roof of the Shizuoka Plant in September 2024. In April 2025, a solar carport was installed in the parking area of the Ota Door Plant. 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 of these initiatives, Sanwa Shutter Corporation's CO2 emissions (Scope 1 + 2) in FY2024 decreased by 13.2% compared to the base year of FY2019, achieving the FY2024 target of a 10% reduction from FY2019 levels (a 6.2% decrease compared to the previous year). Nationwide emissions also decreased by 4.4% compared to the previous year. We will continue to promote measures to achieve the FY2027 target of a 20% reduction from FY2019 levels, as announced in the Medium-Term Management Plan 2027.

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 2024 were 26,743t-CO2 (Scope1: 8,781 t-CO2, Scope2: 17,961 t-CO2), representing an approximately 5.4% increase from the previous year.
Pensacola plant of ODC uses computer-controlled lighting and an energy-efficient air-conditioning system in order to reduce unnecessary energy 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 2024 were 16,425t-CO2 (Scope1: 10,806 t-CO2, Scope2: 5,619 t-CO2), representing an approximately 4.0% decrease from the previous year.
Within the NF Group, ISO 14001 certification has been obtained at the Riexinger plant in Germany, the NF Door plant in Poland, the RobustAB's plant in Sweden, and Vertriebs sales company in Germany. In addition to efforts to reduce energy consumption, the group is promoting the transition of company-owned vehicles in Germany and the UK to electric or plug-in hybrid models, as well as the purchase of electricity derived from renewable energy sources.

Initiatives to Reduce Energy Consumption and CO2 Emission (Asia)

In FY 2022, Asian subsidiaries began calculating CO2 emissions (Scope 1 + 2) from Asian subsidiaries headquarters and all plants. The results FY 2024 were 1,767 t-CO2 (Scope1: 386 t-CO2, Scope2: 1,381t-CO2), representing an approximately 43.6% decrease 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. Starting in FY2024, calculations for Categories 2, 5, 6, 7, 10, and 11 were newly introduced. 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.
