  • *1Calculated for the period from January to December of each year.
  • *2Scope 1 is the equivalent of CH4 emissions from wood chips used for fuel drying. CO2 generated by combustion of biomass fuel is not included because it is reabsorbed.
  • *3For electricity used in our Scope 2 development and operation activities (2024-2025), we are purchasing non-fossil fuel certificates equivalent to our consumption.
