  2. CALCULATION EXAMPLE I Enterprise Gross emission ISIC 20: 70 Gross emission Households: 30 + 60 = 90 Net emissions ISIC 20: 7 Net emissions Households: 3 + 60 = 63 Households Chemical production (ISIC 20) 70 30 Calculation steps WWTP Removal rate WWTP: 1 - 10/(70+30) = 90% 60 Reallocated load ISIC 20: 70 * (1 – 0.90) = 7 Sewerage (ISIC 37) Reallocated load Househ.: 30 * (1 – 0.90) = 3 10 Fresh surface water
