The increasing CO2 concentration in the Earth’s atmosphere, mainly caused by fossil fuel combustion, has led to Global Warming, which is at the present the most crucial environmental issue in the environmental sciences. Increase of greenhouse gases and among them Carbon dioxide (CO2) which is known as the most important greenhouse gas has led to multiple environmental problems such as higher global temperature, ecosystems distortion, and many other major damages to different terrestrial and aquatic ecosystems on the Earth planet. In recent years many governmental and nongovernmental agencies (NGOs) have focused on this issue. Many methods have been suggested to sequester Carbon dioxide from the atmosphere such as geologic sequestration, ocean sequestration, etc. But since they are very costly and in some cases non applicable, sequestration by the use of plants from aquatic and terrestrial ecosystems seems to be more efficient and economic which is mentioned in the Clean Development mechanism (CDM). In this study pistia stratiotes was selected to estimate the plant potential to sequester carbon dioxide in a liquid medium. Pistia stratiotesis a genus of aquatic plant in the family Araceae,comp rising a single species, Pistia stratiotes, often called water cabbage or water lettuce. Its native distribution is uncertain, but probably pans tropical; it was first described from the Nile near Lake Victoria in Africa. It is now present, either naturally or through human introduction, in nearly all tropical and subtropical fresh waterways. In India pistia stratiotes is found in many parts of the country .Carbon dioxide which is on of the most essential nutrients for plants growth was injected in to a water tank of 200 liters capacity. Whereas a blank medium was also run as a comparative medium. Biomass increase of the plant was estimated due to Co2 injection in a period of 1 mount study.
