Contributing to Sustainable Development

Chemical products and materials, which are used in automobiles, electronics, general commodities, medical and healthcare, foods, housing, energy, and countless other products, contribute to improving and enriching the quality of life around the world. It is not an overstatement to say that material development in the chemical industry is a key factor in many breakthrough innovations.

The chemical industry has the potential to be a solution provider to some of the world’s most pressing social issues and must rise up to meet such challenges. Reducing greenhouse emission, which is one of the major causes of global climatic change, help in the development of new renewal energies, bolster agricultural produce to meet the needs of explosive population increases, and respond to requirements of aging society around the world, are just some of the issues that chemical industry can help to resolve.

Prior to this 20th anniversary milestone, we have taken steps to discuss what we must continue and what we must change as a group to ensure our sustainable growth.

Recognizing the importance of a cohesive society in harmony with the environment, health and happiness in an aging society, and industrial platforms in harmony with local communities, the Mitsui Chemicals Group has reconfirmed its commitment to help resolve these issues, in which economic, social, and environmental concerns are connected, through its business activities.

Based on the aforementioned, the Mitsui Chemicals Group is targeting sales of 2,000 billion yen and operating income of 200 billion yen under its 2025 Long-Term Business Plan.
