Climate change overshadowing the globe is a vibrant phenomenon now days. Decades have passed since scientists from around the world started informing and forecasting the impact of this threatening climatic condition. It is not only disseminating the likely consequence, but also scientists have been battling to uphold safe environment for the next generation. Politicians have also been making climatic issue discussion on the top of their agenda on different world summit. As has been mentioned several times, this unfortunate environmental feature came in to being by human activity (directly or indirectly) and is believed to be reversed by same creature. This review is intended thinking that safe chemical process (from simple laboratory experiment to huge industrial process), reduced effluent to the environment and minimized cost to the process, which can be brought about by utilization of ionic liquids, could be one of the elements to retard and/or stop this catastrophe. In this regard, an attempt has been made to include the meaning, history, properties and different applications of ionic liquids, the green chemistry.
