Abstract
This work represents a review of biodiesel production in the world. European Union policy and aims are to reduce increased emission of gases, carbon dioxide in particular, which cause the greenhouse effect due to an increase in demand and use of fossil fuels. A graphical display is given showing the production of oilseed plants: sunflower, soybean, and oilseed rape, with a special overview of the countries which are leading producers of this alternative fuel. Studies are made for biodiesel, showing that the total energy balance is positive, and for this reason give the material and energy the balance of biodiesel production. Regulations and aims directed to increase the production of biodiesel are also shown as well as possibilities for obtaining and using this ecological fuel.
