Mixing fossil fuels with biofuels will be obligatory in Mozambique as of 2012, and the government expects the measure to reduce the cost of importing oil derivatives, specifically gasoline and diesel, Mozambican newspaper Notícias reported. The regulation recently approved by the government sets a mixture of 10 percent ethanol with 90 percent gasoline and 3 percent biodiesel with 97 percent diesel. These percentages were based on installed capacity for production of these fuels in Mozambique, according to the Energy minister, Salvador Namburete. With this measure the government expects in 2012 to save around US$22 million on its fossil fuel import bill that is currently estimated at US$500 million per year.
