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
