Achieving the AWS Certification for Water Stewardship

First in Japan to earn International Certification for Water Stewardship, the Alliance for Water Stewardship (AWS)

The Suntory Group has achieved the first AWS International Certification in Japan for the Suntory Okudaisen Bunanomori Water Plant (Tottori Prefecture) in 2018, followed by the Kyushu Kumamoto Plant (Kumamoto Prefecture) in 2019, the Minami Alps Hakushu Water Plant (Yamanashi Prefecture) was the third to be certified in 2021, and the Suntory Kyushu Kumamoto Plant has received “Platinum,” the highest rating within the Alliance for Water Stewardship (AWS) certification in 2023. This page introduces its significance.

Why Suntory is promoting the AWS

Suntory has been providing new values to people through its products and services to enrich their lives, which is the core of our business. Water is the most critical resource required for us to continue offering value to the customers and the essential resource for local communities and the ecosystem. Furthermore, water is a local resource that circulates depending on the local climate and geographical conditions. Evaporated sea water becomes clouds, rain down to become part of a river or groundwater, and then join larger rivers and back to the sea. This geographical zone is called a catchment. The water we withdraw to produce our products is part of the water cycle, connected to the more significant flow of the catchment like rivers or underground aquifers. Suntory regards itself as a part of the natural water cycle and promotes water stewardship activities in catchments around its plants to preserve the healthy water cycle.

Water stewardship indicates the responsible management and planning of water resources at the catchment level in collaboration with key stakeholders such as governmental agencies and the local community, in addition to managing water within our own plants. The initiative aims to promote the use of water that is socially and culturally equitable, environmentally sustainable, and economically beneficial throughout the entire catchment. The Suntory Group conduct initiatives to contribute to a healthy water cycle in the watersheds based on the Suntory Group’s “Sustainable Water Philosophy,” which has four pillars—understanding the natural water cycle, promoting environmentally conscious water use, conserving watersheds, and engaging with the local community. In addition to using water carefully through continuous water-saving activities and wastewater management at plants, the Suntory Group established the Institute for Water Science in 2003 to conduct hydrologic studies and scientifically understand the water cycle in watersheds around our plants. In the same year, the Natural Water Sanctuary Initiative began in the Kyushu Kumamoto Plant to conserve the water source, have now expanded the area to 22 locations totaling about 12,000ha in Japan and achieved the target of recharging more than twice the amount of water withdrawn by our plants in Japan. We continue to realize our vision for the next 50 and 100 years with the support of experts in various fields and residents and to create a forest that nurture groundwater for the watersheds.
Moreover, we conduct the Suntory Mizuiku-Education Program for Nature and Water at the Natural Water Sanctuaries and local elementary schools near Tennensui Water Plants and cooperate with local government agencies and the community to monitor the catchments’ groundwater level and water resources. Furthermore, we implement forest maintenance and paddy impounding to recharge groundwater and disseminate attractiveness to vitalize local communities under signed partnership agreements with local government agencies. Suntory became the first company to earn the internationally respected standard for water stewardship in Japan, the AWS Certification, to continuously deepen such integrated water resource management itself along the “Sustainable Water Philosophy.”

About AWS

The Alliance for Water Stewardship (AWS) is an organization globally promoting water sustainability established by NGOs, such as the World Wildlife Fund (WWF), The Nature Conservancy (TNC), and companies. The AWS Certification is an international certificate for sustainable water use targeting plants globally and aims to promote water stewardship.

For the certificate audit of Okudaisen Bunanomori Water Plant, Suntory Kyushu Kumamoto Plant, and The Minami Alps Hakushu Water Plant, the assessment body were highly evaluated our integrated water resource management; understanding of the water balance in the catchment around the plants, in line with the Suntory Group's "Sustainable Water Philosophy," water source conservation based on scientific data, water saving and water quality management initiatives at plants, our work with stakeholders, and appropriate disclosure.

About the Partnership Agreement

Suntory Holdings received the request from the AWS to take leadership as a company that leads the promotion of water sustainability in Japan. Endorsing its purpose, we signed a partnership agreement with AWS Asia Pacific in February 2021 followed by signing between Suntory Holdings and AWS International Secretariat in 2023. We also became the first company with AWS membership in Japan.
As the initiatives under the partnership agreement, we supervised the Japanese edition of the AWS International Standards issued in August 2021. We also introduced the certification of the AWS for Suntory Kyushu Kumamoto Plant through a case study, etc., of water source conservation activities by winter paddy impounding at the 4th Asia Pacific Summit held in April 2022, in cooperation with the Water Stewardship Asia Pacific. Suntory will advocate the importance of water resource management by the private sector. In addition, in February 2023, we established the AWS Japan Day Executive Committee with WWF Japan and held Japan's first "AWS Conference - Responsible Management of Water Resources in the Watershed for Businesses," which was attended by numerous Japanese companies, central ministries, local governments, universities, and NGOs. We will continue to lead the networking with stakeholders to promote water stewardship.
