Corporate Obligations and ResponsibilitiesMeasures to Mitigate Waste and Climate Change

Yahoo Japan Corporation (“Yahoo! JAPAN”) works to reduce environmental impact of business activities and at the same time promote initiatives to address climate change issues in our business.

Climate Change Initiatives

Consideration for the environment is indispensable in business development. In Yahoo! JAPAN and its subsidiaries, we employ the latest technology as part of our measures against climate change, which include the construction of environmentally friendly next-generation data centers.
In addition, we employ ecohai in which small packages are delivered by bicycles in our Yahoo! Shopping business. Yahoo! JAPAN and its subsidiaries will continue to thrive in achieving a sustainable society through our business, and to tackle climate change by reducing the environmental impact derived from our business activities.
Moving forward, we plan to increase the use of clean energy and methods with lower environmental impacts at the new office in Kioicho, Tokyo and our data centers, in addition to pursuing a number of measures such as utilizing local ingredients at company cafeterias and cooking with environmentally friendly ingredients.

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 taken on efforts to conserve forest resources while emphasizing 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 menus that are changed every day.
We also recycle uninterruptible power supply (UPS) batteries at our data centers.
