Analysis on Correlation between CO 2 Emissions and Production, Acreage of Crops using Environmental Input-Output Analysis

South Korea is under pressure to reduce emissions because of expanding request for reducing emissions. In many industry sectors, emissions were analyzed to reduce emissions. But little effort in researching agricultural sector has been undertaken because it is recognized as environmentally friendly industry. The object of this research is to estimate emissions of crops and analysis on correlation between emissions and production, acreage of crops. In this study, environmental input-output analysis was used to estimate emissions of agricultural sector and spearman correlation coefficient was used to analysis on correlation between emissions and statics like production and acreage. As a result, rice, barley, pulses and horticultural specialities had correlation with acreage and correlation coefficients of these crops were 0.800~0.933. Regression equations about emissions and acreage of rice, barley, pulses and horticultural specialities was made and of these equations were 0.615~0.929. Using equations, emissions of rice, barley, pulses and horticultural specialities can be estimated with acreage.
