    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/tFULife Cycle Assessment

  • Life Cycle Assessment

    The impacts most commonly considered in LCA are

    Non-renewable resource depletionGlobal warmingOzone depletionAcidificationEutrophicationPhotochemical oxidant formationHuman toxicityAquatic toxicity

  • Life Cycle Assessment

  • Life Cycle Assessment

    EGWP = (ecCO2)BCO2 + (ecCH4)BCH2

    = 1(1) + 21(0.6)

    EGWP = 13.6 kg CO2 equiv / tFU
