Extraction Production Use Disposal
CO2 = 0.2 kg/tCH4 = 0.1 kg/tx1 = 2t/tFU
CO2 = 0.3 kg/tCH4 = 0.1 kg/tx2 = 1.5t/tFU
CO2 = 0.1kg/tCH4 = 0.1kg/tx3 = 1t/tFU
CO2 = 0.1kg/tCH4 = 0.3kg/tx4 = 0.5 t/tFU
x1 x2 x3 x4
FU
The system in this example has one functional output andeach activity i from extraction of raw materials to final disposal generates a certain amount of CO2 and CH2.
Using the Environmental Burdens equation the total environmental burdens per functional unit related to the emissions of CO2 and HC4 are therefore
BCO2 = ∑bcCO2 . xi = (0.2)2+(0.3)1.5+(0.1)1+(0.1)0.5 →BCO2 = 1.0 kg/tFU
BCH4 = ∑bcCH4 . xi = (0.1)2+(0.1)1.5+(0.1)1+(0.3)0.5 →BCH4 = 0.6 kg/tFU

The impacts most commonly considered in LCA are
•Non-renewable resource depletion•Global warming•Ozone depletion•Acidification•Eutrophication•Photochemical oxidant formation•Human toxicity•Aquatic toxicity

EGWP = (ecCO2)BCO2 + (ecCH4)BCH2
= 1(1) + 21(0.6)
→ EGWP = 13.6 kg CO2 equiv / tFU
