The Daicel Group aspires to realize its Basic Philosophy of becoming “The company making lives better by co-creating value,” and it continues to conduct its businesses with a view to both improving social sustainability and enhancing medium- to long-term corporate value.
Our sustainability website provides our various stakeholders with a comprehensive array of detailed non-financial information, including the Daicel Group’s concept of sustainability and sustainability efforts made in the current fiscal year.
We also archive PDF copies from the sustainability site at the time of each year’s disclosure as Daicel Group’s Sustainability Reports for that fiscal year.
We also encourage all stakeholders to read Daicel Report, which provides a concise account of our approaches and efforts toward improving the Daicel Group’s medium- to long-term corporate value.
In the editing of both the Group’s reports and website, attention is given to ensuring information disclosure on our approaches and is presented in a logical and easy-to-follow format.
