Abstract: Energy and exergy utilization and carbon dioxide emission during production of soybean, sunflower, and olive oils are assessed. In all cases, agriculture is the most energy and exergy intensive process and emits most of the carbon dioxide, and diesel is the dominant energy and exergy source. The cumulative degree of perfection (CDP) for soybean and olive oil is 0.92 and 0.98, respectively, whereas the CDP for the sunflower oil is 2.36. Decreasing diesel consumption with good agricultural practices and substituting with biodiesel from renewable resources would decrease the cumulative exergy consumption, as a result, CDP of olive and soybean oil rises to 1.6 and sunflower oil to 2.9.
