Carbon dioxide (CO2)

We aim to reduce emissions of carbon dioxide (CO2), a major greenhouse gas, by working to reduce electricity consumption to help prevent global warming. We are working to reduce electricity, gas, and gasoline consumption by optimizing the operating conditions of air conditioners and server systems for heating and cooling, stopping the idling of vehicles, switching to LED lighting, and turning off unnecessary lights in offices.
The graph below shows the change in CO2 emissions of our company and domestic subsidiaries over a five-year period from FY2018 to FY2022. As Chemical Solution Company electricity supply through the digital grid platform started at two business sites in the Chubu area from the June inspection date in FY2020, the emission factor was changed from the base factor to the adjusted emission factor from FY2020 onward. CO2 emissions decreased 8.2% on a non-consolidated basis and 20.4% on a Group basis due to a decrease in production at Group companies.

Standards for calculation
  • Electricity: Based on "Actual and adjusted emission factors for each electric utility" published by the Ministry of the Environment.
  • Gas, gasoline and kerosene: Based on the "List of Calculation Methods and Emission Factors in the Calculation, Reporting, and Publication System," revised March 2010, published by the Ministry of the Environment.
  • *From FY2022, Sustana (CO2 calculation system) has been introduced to manage coefficients.
