The purpose of this article is to construct sustainable growth models, measure sustainability of the different directions, and estimate the impact of CO2 reduction on GDP growth based on production frontier approach. The OECD countries showed high inefficiencies in the direction reducing only CO2 emission among the three directions for sustainable growths, while they reported low inefficiencies in the direction improving GDP and contracting CO2 emission simultaneously. The most efficient countries in the three directions were United Kingdom, Switzerland, Norway, and Ireland, whereas the most inefficient countries were Korea, Slovakia, Slovenia, and Czech Republic. The OECD countries were classified into four types according to each country"s position in the production frontier. Contracting CO2 emission by 3 percent and 6 percent in the actual GDP levels of the OECD countries, the annual average GDP growth rates were reduced as much as 0.8 percent and 1.7 percent, respectively. The impact of CO2 reduction on the GDP growth of OECD countries was different by each country"s types in the production frontier.
