  1. Life Cycle Assessment (LCA), Bottom-Up model (BU) and Computable General Equilibrium (CGE) model LCA: Focused on one product and tracesthe environmental load occurred upstream and down stream in production / disposal. Good for calculating a perturbation effect of usage / preference change of the product Usually ignore the substitution effect among production factors, intermediate goods for production. Focused on the material chain cycle of good’s production and disposal. BU: The quantities to be produced /consumed are prescribed. Calculates the effect of improvement of production technology, required amount of product and so on. The reduction efforts of energies / products are not reflect to the prescribed quantities to be produced

  2. Life Cycle Assessment (LCA), Bottom-Up model (BU) and Computable General Equilibrium (CGE) model CGE: Focused on the mutual interaction on economic sectors, and calculate the interactive effects among technology improvement, change of consumer preference, economic policies. Focused on the financial /economic chain cycle of good’s production and consumption AIM/Material : Coupling of LCA and CGE strong-ness, the model describes environmental loads from the view point of material chain cycle and financial /economic chain cycle.

  3. Energy and Material Chain Cycle produced commodity (goods and bads) abroad pollution management pollution recycle CO2 import export production sector market energy intermediate CO2 environmental capital and labor energy intermediate CO2 capital labor household energy final demand pollution

  4. LCA approach produced commodity (goods and bads) abroad pollution management pollution recycle CO2 import export production sector market energy intermediate CO2 environmental capital and labor energy intermediate CO2 capital labor household Focused on one product pollution

  5. Bottom up approach produced commodity (goods and bads) abroad pollution management pollution recycle CO2 import export Focused on energy efficiency change mechanism and its effect market energy intermediate CO2 environmental capital and labor environmental Industry/investment energy intermediate CO2 capital labor Household energy service prescribed Focused on household production efficiency change pollution energy final demand

  6. AIM/Material produced commodity (goods and bads) abroad pollution management pollution recycle CO2 import export production sector market energy intermediate CO2 environmental capital and labor environmental Industry/investment energy intermediate CO2 capital labor household energy final demand pollution
