South Korea is under pressure to reduce CO©� emissions because of expanding request for reducing CO©� emissions. In many industry sectors, CO2 emissions were analyzed to reduce CO©� 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 CO©� emissions of crops and analysis on correlation between CO©� emissions and production, acreage of crops. In this study, environmental input-output analysis was used to estimate CO©� emissions of agricultural sector and spearman correlation coefficient was used to analysis on correlation between CO©� 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 CO©� emissions and acreage of rice, barley, pulses and horticultural specialities was made and R©�of these equations were 0.615~0.929. Using equations, CO©� emissions of rice, barley, pulses and horticultural specialities can be estimated with acreage.
