Abstract: Human life on land is vitally dependent on fresh water along with food and air. Many areas in the world do not have access to fresh water. Growing demands of freshwater resources are creating an urgent need to develop self sustained system to meet the demand. At present, many distillation methods are available like reverse osmosis, thin film distillation multi-effect fresh evaporation but they are energy intensive or contribute to environmental degradation. Distillation is one technique used for treating available brackish water into fresh water. However, solar energy can be used as an alternative source of energy for water distillation. In this paper, carbon dioxide emission, mitigation and carbon credit earned from a double slope active solar still under forced circulation mode has been carried out. It has been observed that carbon dioxide emission and carbon credit earned over the life time of 15 years are 2.55 tons and €220 respectively.

Keywords: solar stills; carbon dioxide; CO2; carbon emissions; carbon credit; brackish water; fresh water; solar energy; solar power; water distillation; forced circulation.
