Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that it has been listed in the 2015 Global 100 Most Sustainable Corporations in the World (Global 100) Index, a global ranking by Canada-based media and investment advisory company, Corporate Knights, Inc. This marks Eisai's third inclusion on the list in as many years, and Eisai is the only company from Japan to be included in 2015.

The Global 100 Index evaluates the sustainability of approximately 4,000 of the world's major corporations based on various corporate initiatives in areas such as the environment, society and governance. Since 2005, those companies ranking among the world's top 100 have been announced each year at the World Economic Forum in Davos. The index is based on 12 key performance indicators, including energy productivity, innovation capacity, percentage tax paid, safety performance and leadership diversity, with the evaluations carried out based solely on data publicly disclosed in annual reports, corporate sustainability reports, or through other such channels. In this year's Global 100 Index, Eisai is the only Japanese company to be listed and ranks in 50th place overall.

The Eisai Group's corporate philosophy is to give first thought to patients and their families and increase the benefits that health care provides as well as address diverse healthcare needs worldwide. Guided by this philosophy, Eisai will continue to develop innovative new drugs and make them available to patients around the world as early as possible to fulfill its social responsibility and secure the trust of stakeholders.
