EIO-LCA in-depth discussion
Impact by sector
• Emission / Unit Demand
• Impact / Unit Demand
• Impact from each sector
• Impact from household consumption
• Impact driven by import and export
Impact by sub-region
• Household demand induced impact over all counties
• Regional comparison of supply and environmental loading
• Scenario comparison of sustainable consumption
– Sensitivity of consumption style on impacts
– Impact by regional
consumption behavior
– Energy tax
