In this study, phytocapping which was widely and deeply studied in USA and Australia was investigated among the methane oxidation technology for the surface emission reduction, and the consideration matter to apply the technology was also suggested. The selection of plants to be suitable in climate and soil condition is the key factor when phytocapping would be introduced. In the United States, a fast growing, perennial and deep-rooting tree species are used for landfill covers or contaminated soil areas, and even understory grasses are chosen based on regional characteristics. However this phytocapping would have regional limitation, especially precipitation is an important environmental factor.
