CALCULATION EXAMPLE I Enterprise Gross emission ISIC 20: 70 Gross emission Households: 30 + 60 = 90 Net emissions ISIC 20: Net emissions Households: Chemical production (ISIC 20) 7 3 + 60 = 63 Households 70 30 Calculation steps WWTP 60 Removal rate WWTP: 1 - 10/(70+30) = 90% Reallocated load ISIC 20: 70 * (1 – 0. 90) = 7 Sewerage (ISIC 37) Reallocated load Househ. : 30 * (1 – 0. 90) = 3 10 Fresh surface water
