The YAMADA HOLDINGS Group recognizes that tackling climate change is one of the most important issues, and as such, is making various efforts to reduce CO2 emissions in all of its business activities. In line with the TCFD recommendations that we endorsed in March 2021, we strive to better disclose information related to climate change, and we are also working on measures through our business activities to contribute to the realization of a sustainable society.
With the aim to reduce CO2 emissions stemming from our business activities, we are actively working to reduce emissions at the customer’s product use stage by promoting replacement energy-saving home appliances.
The total volume of Scope 1 and 2 emissions in the YAMADA HOLDINGS Group for the fiscal year ended March 31, 2023 decreased by 29 kt-CO2 year-on-year to 287 kt-CO2.
The YAMADA HOLDINGS Group is continually working to reduce CO2 emissions associated with its business activities. In order to reduce CO2 emissions from electricity use, 2.16% of the total is covered by renewable energy.
The YAMADA HOLDINGS Group started calculating CO2 emissions for the entire supply chain from fiscal 2021 in order to reduce the environmental impact in all its business activities. Of the Scope 3 emissions for fiscal 2022, use of sold products (Category 11) accounted for the largest share at 78% of the total, followed by purchased goods and services (Category 1) at 19%. We will continue to monitor and reduce CO₂ emissions throughout the supply chain.
The YAMADA HOLDINGS Group is striving to reduce the amount of energy it uses. The Group is working to visualize the amount of electricity through energy-saving activities, such as switching to LED lighting in its offices and stores, and through an application that analyzes electricity usage by equipment and time using demand controllers.
YAMADA HOLDINGS has been using green power since the fiscal year ended March 2009. 100% of the power used at the Yamada headquarters building in Takasaki City is green power. Moreover, the rooftops of stores have been used to install solar power systems. In the fiscal year ended March 31, 2023, we generated 49,145 MWh*, helping to reduce our impact on the environment through the sale of electricity. We will continue our effort to promote and expand the use of renewable energy throughout the Group.

To promote energy-savings in its distribution, YAMADA DENKI has requested its outsourcing and partner companies to turn off their idling engines while out delivering products, maintaining a high implementation rate of over 98% in fiscal 2023. In addition, the Group is promoting eco-friendly logistics such as by considering the use of electric vehicles for use at stores and by reducing distances covered during product delivery through the creation of an efficient logistics system for vehicles moving between stores.
In July 2021, the YAMADA HOLDINGS Group created the YAMADA GREEN logo as a symbol of its commitment to the environment. The five letters of GREEN embody the meanings of Global, Resource, Ecology, Evolution, and Next. It expresses our determination to realize a resource-recycling society and further contribute to the creation of a sustainable society. In conjunction with this logo, we have also established the YAMADA GREEN Certification System whereby companies can display the YAMADA GREEN logo on products, initiatives, and reused products that meet YAMADA HOLDINGS’ own environmental standards. (Not applicable to energy-saving home appliances.) Sony’s LinkBuds S (WF-LS900N) series of fully wireless headphones were certified as YAMADA GREEN in fiscal 2023. All models in the series use recycled plastics for the resin material of the headphones and case. These plastics are made from resin collected from the factory. Moreover, by eliminating the use of plastics in individual packaging, Sony has been able to reduce its impact on the environment. In seeking to find new design concepts that utilize recycled materials, Sony’s new Earth Blue colored headphones launched on November 4, 2022, use recycled materials from water bottles in the headphones and case.

YAMADA HOMES is seeking to provide eco-friendly housing and services such as improving heat insulation and adopting advanced energy-saving equipment and solar powers to make Zero Emission Homes (ZEH) more widely known. At the same time, the Company aims to protect the global environment and realize a comfortable and prosperous life for Group customers by promoting a lifestyle that does not waste energy. The YAMADA HOLDINGS Group has set a goal of increasing the ZEH rate to 50% of all homes sold by YAMADA HOMES by 2025, thereby actively working to make emissionfree homes more widespread.
The YAMADA HOLDINGS Group is looking to make the concept of resilient homes, with solar power and storage batteries, more well known. A resilient home is one that can independently supply energy even in an emergency, while controlling energy consumption in normal times. It is hoped that solar power systems equipped with Home Energy Management Systems (HEMS) that “visualize” electricity costs and energy generated will have the effect of raising awareness about saving energy without wasting any of the energy created. The YAMADA HOLDINGS Group continues to make proposals for the installation of solar panels, actively encouraging solar panels be fitted not only on newly built houses but also for renovation projects. Going forward, the Group will help build a safe and secure society through proposals for YAMADA HOMES’ disaster-proof homes, Felidia, and houses equipped with the Hinokiya Group’s Canadian Solar photovoltaic system.
The Hinokiya Group is focusing on selling custom-built homes equipped with its Zekkucho system which can keep temperatures around the home comfortable all year round, thanks to its outstanding airtightness and insulation. Owing to their W-Barrier construction method of Aqua Foam insulation and aluminum heat shielding which blocks infrared rays, the homes built by Hinokiya are extremely airtight and incredibly well insulated. By the end of April 2022, up to 20,000 homes were fitted with the Zekkucho system, and the Group will continue to make every effort to provide more comfortable living spaces going forward.
