Green Logistics Externalities of Freight Transportation Economic Impacts1.Traffic Congestion 2. Resource waste Ecological Impacts:1. Greenhouse Gases Cause Climate Change 2. The use of non-renewable fossil fuel 3. The effects of waste products such as tires and oil 4. Ecosystem destruction and species extinction Social Impacts:1. Negative public health impacts of pollution 2. Crop destruction 3. Injuries and deaths resulting from traffic accidents 4. Noise 5. Visual intrusion 6. Congestion deterring passenger travel 7. Loss of Greenfield sites and open spaces 8. Deterioration of Buildings/Infrastructure Adapted from UK Roundtable on Sustainable Development (1996)

Life-Cycle Assessment of Passenger Transportation Problem Statement Transportation emissions are typically evaluated from the vehicle tail-pipe –Vehicle life-cycle is ignored (i.e. manufacturing and disposal) –Mode and fuel infrastructure is ignored Policy is created and decisions are made based on tail-pipe emissions –e.g. CAFE standards A thorough understanding of human health and environmental impacts requires knowledge of emissions from the mode’s life-cycle

Life-Cycle Assessment of Passenger Transportation Methodology A life-cycle emissions inventory will be created –Modes: automobile, bus, heavy rail, and light rail –For each mode: inputs and outputs from infrastructure, vehicle, and fuels Hybrid LCA –Combines the positive aspects of process based LCA and economic input-output based LCA –Goes beyond vehicle tail-pipe; quantifies effects in the supply chain IVF Design Production UseX End-of-Life I=Infrastructure, V=Vehicle, F=Fuels EIO  Supply Chain Product Process- Based

Life-Cycle Assessment of Passenger Transportation Emissions Inventory Energy Inputs –Electricity and fuel use Emissions Outputs –Criteria air pollutants (SO 2, CO, NO X, VOC, Pb, PM 10 ) –Greenhouse gases (CH 4, CO 2, N 2 O) Quantification and location of inputs/outputs in the supply chain: –Improve decision-making processes –Applicability of abatement technologies
