To fully evaluate the effectiveness of various measures for reducing emissions of CH4 and N2O, we have studied and analyzed the effectiveness and cost of various technologies used for controlling these gases. As a final evaluation, we did the research necessary to develop a cost-benefit ratio analysis. Since it can be assumed that employment of these technologies have a significant effect on the primary objectives of the facilities, besides just the control of CH4 and N2O emissions, these related effects were also studied. While doing this research, an effort was made to gather information on details on present emission control (EC) technology, objectives of present research, requirements, and progress of EC technologies development, as best possible for development of evaluation methods, taking into consideration past research and efficiency. By setting realistic assumptions, based on the above studies, analyses were made to estimate feasible reduction rates of individual EC technologies, and the potential overall impact of various technologies on reduction of GHG from various sources. For final evaluation of EC technologies, it is necessary to consider their impacts on the primary objectives of the facilities and other side effects, and it is also necessary to quantitatively consolidate mechanisms that can affect society and industries, and to study modeling such mechanisms. We are proposing here schemes for the future, based on these studies.
