In today’s world, scientists, analysts, and researcher are continuously looking to find effective fuel optimum solution to reduce greenhouse gas emission. Though, there are considerable research going on to mitigate CO2 from existing fuel. Currently, Ethanol has great potential to minimize CO2 from air as it’s blend with agricultural products and most of the existing vehicles support ethanol. On the contrary, LPG is directly derived from natural gas and increases sustainable balance within the environment. However, on recent invention i.e. hybrid technology, known as electric vehicles have more wider benefit to the environment as well as ensuring ‘0’ carbon emission on air.
