This study aims to establish baseline data for sustainable monitoring by applying the green city index (GCI), which is set up to evaluate the city level, to the city of Gangneung-si, which was designated as a pilot city for the Low-carbon Green Growth City project by the Ministry of Land, Infrastructure, and Transportation. The GCI was applied in the framework of European systems, while considering the social and economic status of Korea. Indicators from 7 areas-$CO_2$, energy, building, transportation, water, waste, and quality of atmosphere were analyzed, except for qualitative indicators. Results indicate that total $CO_2$ emissions were 30.8 tons per capita, or 2.2 tons per one million units of real GDP. The total final energy consumption was 0.231 TOE/capita, or 0.317 TOE per one million units of real GDP. The percentage of total energy derived from renewable resources was 0.41% and energy consumption by the building was $433.5Mwh/1,000m^2$. The total percentage of the working population travelling to work daily by public transportation (limited to bus) was 19%. Further, the total annual water consumption was $99m^3/capita$, and the water lost in the water distribution system was $0.057m^3/capita/day$. The total annual waste collected was 0.0077 ton per capita, The annual mean emission were 0.014 ppm/day for $NO_2$, 0.005 ppm/day for $SO_2$, and 0.019 ppm/day for $O_3$. The annual mean for PM10 emissions was $39{\mu}g/m^3/day$.

문제 정의
The present study collected formula and data of Gangneung where was designated low carbon green city in 2009, using GCI system. The study aimed to reflect GCI system which was designed for low carbon green growth city construction and actively applied in Europe, and to propose data frame according to items for the construction of reliable and systemic baseline data construction. Total 14 items of 7 division were analyzed based on the basic data frame, and baseline data for Gangneung green city indicator was constructed.
Accordingly, it is clear there is a need to construct a standard data method and evaluate it continuously. Thus, this study aims to propose a data frame for all the items needed to apply a GCI system, with the goal of building standard data for monitoring in the future.
대상 데이터
For data collection, this study used the national statistics portal to access information about the green climate city registration project, as reported by the Korea Environment Corporation in the Gangneung-si statistics annual report and in statistics from the Ministry of Infrastructure and Transport.
Gangneung has a population of 214,560 people (2015) and a total area of 1,040 km2. It is located in the center of the Baekdudaegan mountain range, on the eastern side. To the east, Gangneung is bordered by the East Sea of Korea; to the west are Nae-myeon, Hongcheon -gun; Jinbu-myeon; and Daegwonryoung-myeon, Pyeongchang-gun.
The study site was Gangneung, chosen by the government as a low-carbon, green pilot city. Gangneung has a population of 214,560 people (2015) and a total area of 1,040 km2.
이론/모형
However, Korea is ranked as a developed country based on its financial and social levels of development. Accordingly, this study has used the European index system, which considers factors such as energy efficiency and reduction of carbon dioxide, and not developing-country hygiene factors such as drinking water quality and septic tank usage.
성능/효과
The multiplicatively weighted application was excluded for base data construction. The seven evaluation items included CO2, energy, building, transportation, water, waste and land utility, and atmosphere quality. Table 1 shows the calculation formula and data sources.
후속연구
As for the limitation of this study, some errors remained in the comparison between previous data of small and midium cities and present formula of Gangneung. Accordingly further studies would be needed related on baseline data construction using GCI, and weighted value application, and ranking formula. Therefore, could secure competitiveness through construction of low carbon green growth city among foreign and domestic cities.
Total 14 items of 7 division were analyzed based on the basic data frame, and baseline data for Gangneung green city indicator was constructed. Based on the formula proposed by this study, it would be able for baseline data construction of each city. Also there is a critical meaning that it would be able to compare the green growth among cities for some period.
