Policy and Basic Approach
The Mitsui Chemicals Group believes that it is important to understand and minimize the negative impacts on the global environment and ecosystems caused by GHG emissions, water resource consumption, and chemical substance emissions into the air, water, and soil in our business activities. To live out our philosophy of "living in harmony with the global environment," the Mitsui Chemicals Group aims to minimize the negative impact on the global environment throughout the life cycle of our products, starting from the planning stage for our business operations, while striving to reduce the environmental impact associated with our business activities and properly manage chemicals to preserve the environment.
In its Responsible Care Policy, the Mitsui Chemicals Group states that it will "assess risks to people and the environment from our products throughout their life cycles, while working to ensure the health and safety of all persons and to reduce the environmental impact of those products," and will actively develop and provide society with products, services, and technologies that contribute to improving people's quality of life and protecting the global environment. In accordance with these policies, we promote environmental preservation by stipulating relevant basic provisions in our company rules on environmental safety management.

*1 Emission and reduction volume at full capacity, which is different than what is shown in the graph on the “GHG and Energy” page.
*2 Reference index
The GHG emissions reduction rate (Scopes 1 and 2) in FY2023 fell short of the goal as a result of the increase in the number of domestic affiliates subject to the calculation and the expansion of the scope to non-energy origin CO2, which is outside the scope of calculation by the Act on Promotion of Global Warming Countermeasures. This was in accordance with the revised scope of calculation to comply with the GHG Protocol.
