Analyzing the Effects on CO₂ Emission of Taxation Stages of Car Purchase, Ownership and Use : Modeling of Car Age/Type Cohort and Structure of Purchase/Owning/Driving Condition of Vehicle

Abstract

This study aims at constructing a tool to examine and provide the information of changes in car market configuration, life cycle CO₂ emission from automobile transport and tax revenues due to taxation policies. In order to quantitatively estimate the effects, a model system which chases the car cohort by engine class and age is developed. It contains models which represent economic behaviors when the tax rates are changed in the stages of purchasing, owning and using of cars. As this model system can forecast the amount of existing cars by engine class and age, it makes possible to examine the effects on reducing CO₂ emissions due to the balance of rates between each stage of taxation.
