¡Ground for Calculation

Emission factor set forth in the Act on Promotion of Global Warming Countermeasures is used in calculating carbon-dioxide emissions.

CO2 emissions derived from wastes are calculated by accepted volume multiplied by the emission factor according to each categories set forth in the Wastes Disposal and Public Cleaning Law. The figure of 0.555 kg Co2/kWh is used as an emission factor for power generation, which is a national uniform emission factor set forth in the Act on Promotion of Global Warming Countermeasures. As a result, the figures may differ from those in the Dowa Group Report submitted to administration authorities. As some of the figures are rounded off to calculate totals, adding up figures in each item may not be equal to the grand total.
