| Research Abstract |
This study empirically analyzes whether there is a relationship between the share of aged population and carbon dioxide(CO_2) emission. The results of analysis indicate that there is a quadratic relationship between CO2 emissions per capita and the share of aged population, and the turning point is around 16 percent. This study also estimates the relationship between factors of CO_2 emission and the share of elderly people. A quadratic relationship exists between the change in the number of passenger vehicles per 1000 persons and the share of elderly people, with the turning point being approximately 17 percent. Therefore, the demographic change is an important consideration in the change of CO_2 emission in transportation sector.
