The YAMADA HOLDINGS Group recognizes responding to climate change as a crucial issue in achieving a sustainable society. To reduce CO2 emissions associated with overall business activities, we are enhancing climate-related disclosures in line with TCFD recommendations and implementing measures through business activities.
To promote the reduction of CO2 emissions from our business activities, our Group actively works to reduce emissions at the product use stage by encouraging customers to replace their appliances with energy-efficient models. Additionally, we have set a CO2 emissions reduction target in fiscal 2024, to reduce greenhouse gas emissions in Scope 1 and 2 by 42% by fiscal 2031 compared to fiscal 2021.
The total volume of Scope 1 and 2 emissions in the YAMADA HOLDINGS Group for the fiscal year ended March 31, 2024 decreased by 5 kt-CO2 year-on-year to 279 kt-CO2.
The YAMADA HOLDINGS Group is continually and proactively working to reduce CO2 emissions associated with its business activities. In order to reduce CO2 emissions from electricity use, 3.74% of all electricity comes from renewable energy sources. Moreover, since June 2022, we have been working to save power in our YAMADA DENKI stores in response to the government’s request to cut down on electricity. By reducing the number of ceiling lights used and turning off appliances on display, we reduced CO₂ emissions from electricity use in fiscal 2024 by approximately 1kt-CO₂ compared to fiscal 2023.
The YAMADA HOLDINGS Group calculates CO2 emissions for the entire supply chain in order to reduce the environmental impact in all its business activities. Of the Scope 3 emissions for fiscal 2024, use of sold products (Category 11) accounted for the largest share at 77% of the total, followed by purchased goods and services (Category 1) at 20%. We will continue to monitor and reduce CO2 emissions throughout the supply chain.
The YAMADA HOLDINGS Group is working to visualize the amount of electricity through energysaving 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.
Reducing energy use is also a consideration in store development. When developing a new store, YAMADA DENKI can reduce energy use by building a single-story structure, eliminating the need to install escalators and elevators to the second floor. Further reductions in energy use have been achieved by improving thermal insulation by reducing the number of windows, and by replacing mercury lamps with LEDs for exterior lighting in stores. Comparing the electricity usage per sq. meter between stores that were built 23 years ago on average to those built 8 years ago on average, the stores with an average age of 8 years showed a reduction in electricity usage of about 15% (as of March 2023).
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. In June 2023, solar panels were installed at the YAMADA East Japan Reuse Center Gunma Plant to provide approximately 55% of the electricity used in plant operations. Moreover, solar panels on store rooftops generated 49,377 MWh* in fiscal 2024, helping to reduce our impact on the environment through the sale of electricity.

In YAMADA DENKI’s logistics operations, we request subcontractors and partner companies to cooperate with turning off vehicles when stopped, maintaining a high implementation rate of over 98% for fiscal 2024. We are also promoting environmentally friendly logistics by reducing the number of vehicles used by devising load capacity, shortening vehicle mileage in product delivery by utilizing an efficiency system for inter-store transfers, and testing the effectiveness of five EV vehicles as business vehicles in stores on a trial basis.
At YAMADA DENKI, employees and sales engineers with extensive product knowledge recommend replacing home appliances with energy-efficient ones when serving customers. Additionally, “unified energy-saving labels” are posted near the relevant products so customers can easily find energy-saving home appliances. In fiscal 2024, the percentage of home appliances (TVs, refrigerators, air conditioners) sold that met the 100% energy-saving standard under the energy-efficiency labeling system was 42.8%, achieving the target of a year-on-year increase.
As the severity of global warming increases, natural disasters caused by climate change are expected to occur frequently in Japan, leading to heightened interest in disaster preparedness products and a potential rise in demand.
The Group sees the promotion of disaster preparedness products as an opportunity to address climate change while responding to these natural disaster risks.
In fiscal 2024, the expansion of sales areas for portable generators, home storage batteries, and disaster prevention goods across all YAMADA DENKI directly operated stores resulted in sale of ¥1,988 million, an increase from the previous year.
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). Sales of YAMADA GREEN certified products for fiscal 2024 totaled ¥3,843 million, achieving our target of a year-on-year increase.

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 net Zero Energy Houses (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. Additionally, the ZEH rate of homes sold by YAMADA HOMES reached 41% in the fiscal year ending February 29, 2024.
The YAMADA HOLDINGS Group aims to popularize resilient homes equipped with solar power generation systems and storage batteries, and actively promotes the installation of solar panels not only in new homes but also in renovation proposals. Additionally, by visualizing solar power generation output and electricity usage with the HEMS monitor, energy created is not wasted, and that this will have the effect of raising awareness about saving energy.
We shipped 33,054 solar panels in fiscal 2024, compared to our target of 50,000 solar panels shipped by fiscal 2031. Moving forward, we will contribute to building a safe and secure society through proposals such as YAMADA HOMES’ YAMADA Smart House and our Energy Revolution Z, which combines the Hinokiya Group’s solar systems with V2H.
