The purpose of this paper is to provide a broad overview of the technical, social, economic and environmental impacts of bio-fuel use. The major factors that are considered in evaluating the impact are: (1) different blending ratio of bio-diesel with diesel in C I engine of vehicles and their performance in terms of power, torque andspecific fuel consumption, (2) Social factors such as population, employment generation, profitability to farmers, regional growth, and changes in land use pattern (3) economic impacts of bio-fuels production are effects on food and agricultural prices including impacts on food security and (4) environmental impacts & greenhouse gas emissions and issues of technology. For purpose of blending, biodiesel can be blended in any proportion with mineral diesel. In comparison with fossil diesel, bio-diesel shows better emissioncharacteristics. The environmental performance of road transport improves by use of it, including decreased greenhouse emissions: substantial reduction in emission of unburned hydrocarbons, carbon monoxide and particulate matter. Factors related to social and economic aspects like employment generation, utilisation ofwasteland, diversity of agriculture land, food prices, reduction in imports fossil due to use of bio-fuel and energy prices can have significant impacts on bio-fuel development. Food security will be affected by the conversion of agricultural land for bio fuel plantation and cause indirect change in land-use pattern.
