Through its online Sustainability site, Mitsui Chemicals’ goal is to provide stakeholders with a deeper understanding of the Group’s efforts to realize sustainable growth in concert with society. The site shines a light on the Group’s three-axis management (economy, environment and society), with a focus on environmental and social initiatives. Taking advantage of the unique features of website, we have made every effort to post comprehensive details encompassing a wide range of areas including the Group’s policies, structure and systems, activities, and numerical data. In addition, plans are in place to issue the Mitsui Chemicals Group ESG Report by October in every year.
