*1 Calculated based on consolidated LTM net sales for the period from January to December of each year (Unaudited by the accounting auditor)
*2 Scope 1 is the equivalent of CH4 emissions from wood chips used for fuel drying.
Scope 2 covers LCCO2 emissions from fossil fuels used in heavy machinery (CO2 generated by combustion of biomass fuel is not included because it is reabsorbed)
