※In accordance with the Ministry of Economy, Trade and Industry's “Guidelines for Retail Electricity Sales,” this means that 100% of the electricity demand is supplied using CO2-zero emission power sources (meaning renewable energy generation facilities and hydrogen power generation facilities) as the power source composition, and that the environmental value is supplied through the use of non-fossil certificates. This does not mean that CO2 is not emitted throughout the entire lifecycle, including the manufacturing and transportation of fuels.

*2 In cases where solar power and other renewable energy sources and storage batteries cannot cover the entire demand, other electricity from the market or other sources may be used. In such cases, some of the electricity supplied will not be carbon-free. However, it is possible to achieve 100% carbon-free electricity by purchasing non-fossil fuel certificates as an option.
