Evaluation Model to Calculate Duplicated Effect of CO₂ Reduction Countermeasures of Road Transportation Sector

Abstract

Concerning CO₂reduction effect from the road transportation sector, the method for evaluating multiple effects of CO₂ reduction countermeasures was constructed. The model made in this research combines automobile fuel consumption model, annual mileage evaluation model and automobile stock quantity stochastic model. This model can calculates the CO₂ emission of road transportation of Japan. Using this model, we evaluate the difference of the reduction effect in two cases; first case is the case in which CO₂ reduction countermeasures individually evaluated and piled up each effects; second case is the case in which the mutual influence of the CO₂ reduction countermeasures considered. From this calculation, the difference of both reduction effects was occurred, and this model is effective for the evaluation of the more accurate CO₂ reduction effect.
