Since the CMP Group uses a variety of chemical substances in its business activities, we recognize the importance of countermeasures against air, water, and soil pollution. To prevent or minimize adverse effects on the global environment and local environments, we comply with laws, regulations, and ordinances, and strive to reduce emissions of pollutants.

The Sustainability Subcommittee’s Resource Utilization and Pollution Prevention Subcommittee works with domestic production sites to implement pollution countermeasures. Factories operated by overseas Group companies are proactively managed in compliance with the laws and regulations of each country. We receive reports on pollutant emissions from domestic Group companies at least four times a year, and from overseas Group companies once a year.

We monitor the amount and concentration of pollutants emitted from facilities subject to the Air Pollution Control Act and manage emissions appropriately in compliance with relevant laws and regulations. In fiscal 2024, the CMP Group’s total emissions of nitrogen oxides (NOx) and sulfur oxides (SOx) from all production sites amounted to 1 ton and 9 tons, respectively. Compared to fiscal 2022, the NOx emission intensity (per unit of production volume) decreased by 50%, while the SOx emission intensity decreased by 59%.

To reduce VOC emissions, we have installed deodorizing equipment and other systems in our factories. At the CMP Group’s laboratories and production sites in Japan, VOC emissions to the atmosphere totaled 116 tons in fiscal 2024, with the emissions intensity (per unit of production volume) increasing by 5% compared with fiscal 2022.

In fiscal 2024, no chemical substances subject to the Pollutant Release and Transfer Register (PRTR) Act were discharged into public waters or soil at any of the Group companies’ business sites in Japan. A total of 90 tons of emissions were released into the atmosphere. Note that the chemical substances subject to the PRTR Act were changed in April 2023, so the emission volume in fiscal 2022 are the actual results for the substances subject to the Act before the change.

At sites subject to regulation under the Water Pollution Prevention Act, we monitored wastewater discharged into rivers, seas, and other bodies of water to ensure that emissions of water pollutants were properly controlled below regulatory limits, thereby preventing any violations of laws and regulations. In addition, we have put in place thorough measures to prevent the leakage of chemical substances in the event of an accident.

In fiscal 2024, the CMP Group reported chemical oxygen demand (COD) of 5 tons and biochemical oxygen demand (BOD) of 2 tons. Compared to fiscal 2022, the COD intensity (per unit of production volume) decreased by 6%, while the BOD intensity increased by 6%.

The Shiga Factory voluntarily measures environmentally hazardous substances in groundwater on the premises to prevent pollution.
