Environmental Data
CO2 emissions of the entire Group, including consolidated subsidiaries
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 CO2 emissions of the entire Group, including consolidated subsidiaries.
As part of our information disclosure based on the TCFD recommendations, we have set a target of reducing emissions by 50% by 2030 compared to FY2022 for the entire Group, including consolidated subsidiaries.
In FY2023, we achieved an 11.5% reduction compared to the base year of FY2022.
