Preserving Natural Capital

To realize a sustainable society, we will give consideration to the impact that our business activities have on ecosystems, make efforts for sustainable procurement, waste management, and protection of water resources and biodiversity, and support initiatives for global environmental protection.

Waste Management

Our Measures on Waste Management

The Z Holdings Group reduces greenhouse gas emissions by reducing the use of paper and electricity in our offices as much as possible. In addition, we promote the practice of "reduce, reuse, recycle" in the company to alleviate the environmental load.

Conversion to Paperless Offices

By distributing laptop computers and tablets to our employees, digitizing materials for meetings to be viewed on computers or with projectors, and promoting online work, we are greatly reducing the volume of printed documents and making the shift to paperless offices.

Promotion of Reduce, Reuse, Recycle

At the Kioicho office in Tokyo, we have reduced energy consumption by switching to LED lighting throughout the entire building, and have promoted reusing and recycling by separating garbage into 15 categories. We have also made efforts to conserve forest resources while ensuring confidentiality and recycling through the use of "Mamoru-kun", a recycling box for used paper. At the company cafeteria, we minimize food loss by using the same ingredients for different menus that are changed every day.
We also recycle uninterruptible power supply (UPS) batteries at our data centers operated by Yahoo! JAPAN

Collection and Recycling of Used Clear Folders

ASKUL has been conducting an experimental project of collecting and recycling clear folders made of a single material and the same shape, and recycling them as new products. The project was chosen as an "experimental initiative for building a recycling system for plastic and other resources to support a decarbonized economy (FY2020)," by the Ministry of the Environment of Japan. Yahoo! JAPAN also cooperated in this experimental project, and collected clear folders equivalent to 251.83kg from its Kioicho headquarters as of August 2021.

Protection of Biodiversity

Initiatives to Protect Biodiversity

As an enterprise that strives to be in harmony with the natural environment, local communities and future society, the Z Holdings Group takes on initiatives to pass on sustainable biodiversity to future generations.

Cooperating with "Future and Coral Project"

The deterioration of the marine environment, which is influenced by climate change, is causing coral reefs to die out. To tackle this issue, SoftBank Corp. along with Onna Village in Okinawa Prefecture--the village that has seeded the most corals in the world--and many other enterprises and organizations, initiated "Future and Coral Project" in order to protect the environment through countermeasures against global warming and conservation of the ecosystem. Yahoo! JAPAN cooperates by raising donations to plant coral seedings through Yahoo! JAPAN Internet Fund Raising and reporting the issue through "Gyoppy!".

Supporting Carbon Offset Campaigns for National Parks and World Natural Heritage Sites

Since August 2017, Yahoo! JAPAN has supported the initiative for the prevention of global warning "Carbon Offset Campaigns Targeting Japan's National Parks and World Natural Heritage Sites" a collaborative initiative between the Ministry of Environment and the Ministry of Economy, Trade and Industry, and participates in the conservation activities in national parks and world natural heritage sites.
In this campaign, energy used and carbon dioxide emitted around the national parks will be reduced or offset by introducing energy-efficient/renewable energy equipment and forest management. By informing the public of these activities, the campaign aims to stimulate action to prevent global warming.
Yahoo! JAPAN purchases J-Credits (*1) through the campaign secretariat office. Half the purchased amount is used for the preservation of national parks and the World Natural Heritage sites. The rest is credited to project participants (*2) and is effectively used.

  • *1: J-Credit Scheme is a scheme under which the Government of Japan certifies credits for the amount of greenhouse gas emissions reduced through efforts made by introducing energy-saving devices, as well as the amount of such emissions removed and volume absorbed through appropriate forest management.
  • *2: Organizations and companies that take initiatives to reduce greenhouse gas emissions and increase absorption volume. J-Credit project participants sell J-credits based on calculations made according to emission reduction and absorption volume and these "credits" can be utilized to reduce the running cost of facilities and to make new energy saving investments.
Efforts to Conserve and Restore Biodiversity by Maintaining Biotope

In an effort to conserve biodiversity and to contribute to local communities, Yahoo! JAPAN is working on an urban development initiative in Kioicho Garden Terrace, where Yahoo! JAPAN's Tokyo office is located, to form an ecological network (corridor) connecting precious greens in central Tokyo. Yahoo! JAPAN is working on this initiative to conserve and recover biodiversity through biotope regeneration.
Specifically, since June 2016, we have been building an environment so that fireflies (which have been identified to inhabit the inner moat of the Imperial Palace close to our office) can now live in the Kioicho biotope, which has become a model for natural regeneration.

Transactions of All Ivory Products Banned in Yahoo! JAPAN's E-Commerce Services

In the past, Yahoo! JAPAN provided opportunities for legal ivory transaction in Japan in compliance with the Law for the Conservation of Endangered Species of Wild Fauna and Flora.
However, we have confirmed multiple reports in which ivories that were traded in Japan through YAHUOKU!, our online auction service, were smuggled abroad and detected by foreign customs authorities. Considering the global situation over ivory trade as well as advice from environmental groups, Yahoo! JAPAN has decided to ban the transactions of all ivory products in its e-commerce services from November 1, 2019.

Protection of Water Resources

Initiatives to Conserve Water Resources

The Z Holdings Group does not require a large amount of water or water of a designated quality for its normal business activities. However, regarding the management of water resources as an important challenge in environmental protection, it analyzes risks and manages the quantity of water intake and discharge. Yahoo! JAPAN's water use largely consists of water used for cooling and humidifying at data centers and water used for employees' office life. For offices, we make efforts to conserve water by using only the amount necessary of our office life, and by using rain water through the building system.

We use industrial water that has high reutilization rate and underground water that has high spring water coefficient for data centers, based on annual plans. Thus, our use has no environmental impact that may lead to the depletion of resources. Since water is only used for cooling and humidification, our water discharge does not cause contamination, either. Management and supervision of drainage is appropriately conducted in collaboration with responsible authorities. Moreover, we endeavor to conserve water resources through measures such as taking in outside air to improve cooling efficiency.

Using World Resources Institute's (WRI) Aqueduct Water Risk Atlas, we periodically check the water stress of the water source from which we receive water supply for our business activities. With regard to the water source of the data centers, which account for the majority of the company's water consumption, we have confirmed that the water stress and overall water risk are not high, with the risk level being "Low-Medium" both in Japan and overseas. We will maintain the monitoring system to continuously watch for changes in water stress, and will take appropriate steps if the water stress is judged to be high.
