  1. Sustainable Production & Consumption • Life Cycle Assessment • Case studies • Streamlined Life Cycle Assessment • Does more consumption make you happy? • Competition

  2. Life Cycle Assessment

  3. Environment System Functional Outputs Inputs Emissions/Wastes Subsystems Life Cycle Assessment

  4. Materials Acquisition Outputs Inputs Principal Products Formulation, processing and Manufacturing Materials Coproducts Product Distribution Energy Water effluents Water Product use Airborne emissions Air Recycle, products, components, materials Solid Waste Other Environmental interactions Waste Management Life Cycle Assessment

  5. x2 x3 x1 x4 Extraction Production Use Disposal FU CO2 = 0.2 kg/t CH4 = 0.1 kg/t x1 = 2t/tFU CO2 = 0.1kg/t CH4 = 0.1kg/t x3 = 1t/tFU CO2 = 0.3 kg/t CH4 = 0.1 kg/t x2 = 1.5t/tFU CO2 = 0.1kg/t CH4 = 0.3kg/t x4 = 0.5 t/tFU Life Cycle Assessment The system in this example has one functional output and each activity i from extraction of raw materials to final disposal generates a certain amount of CO2 and CH2.

  6. Life Cycle Assessment 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

  7. Life Cycle Assessment • 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

  8. Life Cycle Assessment

  9. Life Cycle Assessment EGWP = (ecCO2)BCO2 + (ecCH4)BCH2 = 1(1) + 21(0.6) → EGWP = 13.6 kg CO2 equiv / tFU
