This Study analyzed the electric car effect on the Korea Expressway System in terms of year 2020 CO2
emission. The analysis was based on the green car dissemination goal by the government and year 2010 emission
statistics. Major contents performed in the study area were as follows. First, the greenhouse gases emitted from
the highways were found to be approximately 17.3 million tons of CO2 as of 2010. Analysis showed the emission
would be 17.4 million tons in 2015 and 16.2 million tons in 2020. The results in the pattern reflect the effect of
O/D on the KTBD and the trend of traffic increase from 2015 to 2020 followed by decrease in 2020. Second, in
the case of greenhouse gas emission with the anticipated supply of electric cars, the amount of emission in 2015
will be 17.1 million tons, which is about 2.0% reduction compared to the lack of introduction of electric cars.
The analysis also showed that in 2020, the amount of emission will be 14.2 million tons, which indicates the
effect of reduction is 12.8% compared to non implementation of the program.
