Trends of CO2 emissions

We decreased CO2 emissions by approximately 13.9% in fiscal 2022, which was on par with the levels in fiscal 2017.

The above uses CO2 conversion factor published by the Ministry of the Environment.

Improving transport efficiency

 Although we increased CO2 emissions by approximately 3% in fiscal 2022, compared to fiscal 2017, specific emissions increased by approximately 11% per unit (compared to fiscal 2017). We are nonetheless determined to keep on increasing transport efficiency in the future.

Wastewater

Wastewater levels at all sites were maintained within figures agreed with the relevant local authorities.

Waste

We recycled 91.9% of all waste in fiscal 2022. We are committed to ecycling and will continue to reduce the volume of waste we generate in the future.

Targets and results

In fiscal 2022, we carried out activities based on the following environmental targets.

Emissions and transfers of substances subject to PRTR Act

The following figures were taken in fiscal 2022 in accordance with the PRTR Act (Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof). We will continue to work on reducing emissions in the future.
