The world's top ethanol fuel producers in 2010 were the United States with 13.2 billion U.S. liquid gallons (bg) and Brazil (6.92 bg), accounting together for 88% of world production of 22.95 billion US gallons (86,900,000 m3).[1] Strong incentives, coupled with other industry development initiatives, are giving rise to fledgling ethanol industries in countries such as Germany, Spain, France, Sweden, China, Thailand, Canada, Colombia, India, Australia, and some Central American countries.

Brazil has the largest and most successful bio-fuel programs in the world, involving production of ethanol fuel from sugarcane, and it is considered to have the world's first sustainable biofuels economy.[4][5][6] In 2006 Brazilian ethanol provided 18% of the country's road transport sector fuel consumption needs,[7][8] and by April 2008, more than 50% of fuel consumption for the gasoline market.[5][9][10] As a result of the increasing use of ethanol, together with the exploitation of domestic deep water oil sources, Brazil reached in 2006 a volumetric self-sufficiency in oil supply, but is not effectively self-sufficient, since most of its locally extracted oil is heavy.[11][12][13]
Together, Brazil and the United States lead the industrial world in global ethanol fuel production, accounting together for 89% of worldwide production.[2] In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons),[2] representing 35.9% of the world's total ethanol used as fuel. Sugar cane plantations cover 3.6 million hectares of land for ethanol production, representing just 1% of Brazil's arable land, with a productivity of 7,500 liters of ethanol per hectare, as compared with the U.S. maize ethanol productivity of 3,000 liters per hectare.[4][14]
The ethanol industry in Brazil is more than 30 year-old and even though it is no longer subsidized, production and use of ethanol was stimulated through:
Guaranteed purchase and price regulation were ended some years ago, with relatively positive results. Ethanol producers in the state of São Paulo established a research and technology transfer center that has been effective in improving sugar cane and ethanol yields.[15]
There are no longer light vehicles in Brazil running on pure gasoline. Since 1977 the government made mandatory to blend 20% of ethanol (E20) with gasoline (gasohol), requiring just a minor adjustment on regular gasoline motors. Today the mandatory blend is allowed to vary nationwide between 20% to 25% ethanol (E25) and it is used by all regular gasoline vehicles and flexible-fuel vehicles. The Brazilian car manufacturing industry developed flexible-fuel vehicles that can run on any proportion of gasoline and ethanol.[16] Introduced in the market in 2003, these vehicles became a commercial success.[17] As of December 2010, the fleet of flex vehicles had reached 12 million automobiles and light commercial vehicles,[18][19] plus 515.7 thousand flex-fuel motorcycles.[20][21] The ethanol-powered "flex" vehicles, as they are popularly known, are manufactured to tolerate hydrated ethanol (E100), an azeotrope composed of 95.6% ethanol and 4.4% water.[22]
The latest innovation within the Brazilian flexible-fuel technology is the development of flex-fuel motorcycles.[23][24] The first flex motorcycle was launched to the market by Honda in March 2009. Produced by its Brazilian subsidiary Moto Honda da Amazônia, the CG 150 Titan Mix is sold for around US$2,700.[25][26][27] In September 2009, Honda launched a second flexible-fuel motorcycle, the on-off road NXR 150 Bros Mix.[28] By December 2010 both Honda flexible-fuel motorcycles had reached cumulative production of 515,726 units, capturing a market share of 18.1% of Brazilian new motorcycles produced in that year.[20][21]

The United States produces and consumes more ethanol fuel than any other country in the world. Ethanol use as fuel dates back to Henry Ford, who in 1896 designed his first car, the "Quadricycle" to run on pure ethanol.[22] Then in 1908, he produced the famous Ford Model T capable of running on gasoline, ethanol or a combination of both.[22][31] Ford continued to advocate for ethanol as fuel even during Prohibition.[22]
Most cars on the road today in the U.S. can run on blends of up to 10% ethanol, and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends. In 2007 Portland, Oregon, became the first city in the United States to require all gasoline sold within city limits to contain at least 10% ethanol.[32][33] As of January 2008, three states — Missouri, Minnesota, and Hawaii — require ethanol to be blended with gasoline motor fuel. Many cities also require ethanol blends due to non-attainment of federal air quality goals.[34]
Several motor vehicle manufacturers, including Ford, Chrysler, and GM, sell flexible-fuel vehicles that can use gasoline and ethanol blends ranging from pure gasoline all the way up to 85% ethanol (E85). By December 2009 it was estimated there were 8.4 million E85-compatible vehicles on U.S. roads,[35] though actual use of E85 fuel is limited, not only because the ethanol fueling infrastructures is limited,[36] but also because many owners are not aware their vehicle is flex-fuel capable.[22]
In the USA there are currently about 1,900 stations distributing E85 ethanol, although most stations are in the corn belt area.[37][38] One of the debated methods for distribution in the US is using existing oil pipelines,[39] which raises concerns over corrosion. In any case, some companies proposed building a 1,700-mile (2,700 km) pipeline to carry ethanol from the Midwest through Central Pennsylvania to New York.[40]
The production of fuel ethanol from corn in the United States is controversial for a few reasons. Production of ethanol from corn is 5 to 6 times less efficient than producing it from sugarcane. Ethanol production from corn is highly dependent upon subsidies and it consumes a food crop to produce fuel.[41] In fact, based on current gasoline consumption, it would take 11 acres (45,000 m2) of corn per person to replace the gasoline supply.[42] The subsidies paid to fuel blenders and ethanol refineries have often been cited as the reason for driving up the price of corn, and in farmers planting more corn and the conversion of considerable land to corn (maize) production which generally consumes more fertilizers and pesticides than many other land uses.[41] This is at odds with the subsidies actually paid directly to farmers that are designed to take corn land out of production and pay farmers to plant grass and idle the land, often in conjunction with soil conservation programs, in an attempt to boost corn prices. Recent developments with cellulosic ethanol production and commercialization may allay some of these concerns. A theoretically much more efficient way of ethanol production has been suggested to use sugar beets which make about the same amount of ethanol as corn without using the corn food crop especially since sugar beets can grow in less tropical conditions than sugar cane.[43]
On October 2008 the first "biofuels corridor" was officially opened along I-65, a major interstate highway in the central United States. Stretching from northern Indiana to southern Alabama, this corridor consisting of more than 200 individual fueling stations makes it possible to drive a flex-fueled vehicle from Lake Michigan to the Gulf of Mexico without being further than a quarter tank worth of fuel from an E85 pump.[44][45][46]
On 23 April 2009, the California Air Resources Board approved the specific rules and carbon intensity reference values for the California Low-Carbon Fuel Standard (LCFS) that will go into effect on 1 January 2011.[47][48][49] During the consultation process there was controversy regarding the inclusion and modeling of indirect land use change effects.[50][51][52][53][54] After the CARB's ruling, among other criticisms, representatives of the US ethanol industry complained that this standard overstates the environmental effects of corn ethanol, and also criticized the inclusion of indirect effects of land-use changes as an unfair penalty to domestically produced corn ethanol because deforestation in the developing world is being tied to US ethanol production.[48][55][56][57][58][59][60] The initial reference value set for 2011 for LCFS means that Mid-west corn ethanol will not meet the California standard unless current carbon intensity is reduced.[47][58][60][61]
A similar controversy arose after the U.S. Environmental Protection Agency (EPA) published on 5 May 2009, its notice of proposed rulemaking for the new Renewable Fuel Standard (RFS).[62] The draft of the regulations was released for public comment during a 60-day period. EPA's proposed regulations also included the carbon footprint from indirect land-use changes.[63][64] On the same day, President Barack Obama signed a Presidential Directive with the aim to advance biofuels research and improve their commercialization. The Directive established a Biofuels Interagency Working Group comprising three agencies, the Department of Agriculture, the Environmental Protection Agency, and the Department of Energy.[65][66] This group will develop a plan to increase flexible fuel vehicle use and assist in retail marketing efforts. Also they will coordinate infrastructure policies impacting the supply, secure transport, and distribution of biofuels. The group will also come up with policy ideas for increasing investment in next-generation fuels, such as cellulosic ethanol, and for reducing the environmental footprint of growing biofuels crops, particularly corn-based ethanol.[65][66][67]
In 2010, Growth Energy, an industry lobbist group, claimed that increasing the percentage of ethanol in gasoline to 15% would create 136,000 jobs. The Environmental Working Group said that 27,000 might be created, each costing the taxpayers $446,000 per year (in 2010 constant dollars).[68] In October 2010 the E.P.A. granted a waiver to allow the E15 blend to be sold only for cars and trucks with a model year of 2007 or later, representing about 15% of vehicles on the U.S. roads. As stations are not required to offer E15, a practical barrier to the commercialization of E15 is the lack of infrastructure, similar to the limitations suffered by sales of E85.[69][70]

The consumption of bioethanol in Europe is largest in Germany, Sweden, France and Spain. Europe produces equivalent to 90% of its consumption (2006). Germany produced ca 70% of its consumption, Spain 60% and Sweden 50% (2006). In Sweden there are 792 E85 filling stations and in France 131 E85 service stations with 550 more under construction.[37]
On Monday, 17 September 2007 the first ethanol fuel pump was opened in Reykjavik, Iceland. This pump is the only one of its kind in Iceland. The fuel is imported by Brimborg, a Volvo dealer, as a pilot to see how ethanol fueled cars work in Iceland.
In the Netherlands regular petrol with no bio-additives is slowly being outphased, since EU-legislation has been passed that requires the fraction of nonmineral origin to become minimum 5.75% of the total fuel consumption volume in 2010. This can be realised by substitutions in diesel or in petrol of any biological source; or fuel sold in the form of pure biofuel. (2007) There are only a few gas stations where E85 is sold, which is an 85% ethanol, 15% petrol mix.[73] Directly neighbouring country Germany is reported to have a much better biofuel infrastructure and offers both E85 and E50. Biofuel is taxed equally as regular fuel. Fuel tanked abroad cannot be taxed and a recent payment receipt will in most cases suffice to prevent fines if customs check tank contents. (Authorities are aware of high taxation on fuels and cross-border fuel refilling is a well-known practice.)
Sweden is the leading country in Europe regarding the use of ethanol as fuel, though it has to import most of the ethanol. All Swedish gas stations are required by an act of parliament to offer at least one alternative fuel, and every fifth car in Stockholm now drives at least partially on alternative fuels, mostly ethanol.[74] The number of bioethanol stations in Europe is highest in Sweden, with 1,200 stations[75] and a fleet of 116 thousand flexi-fuel vehicles as of July 2008.[76]
Stockholm will introduce a fleet of Swedish-made electric hybrid buses in its public transport system on a trial basis in 2008. These buses will use ethanol-powered internal-combustion engines and electric motors. The vehicles’ diesel engines will use ethanol.[74]
In order to achieve a broader use of biofuels several government incentives were implemented. Ethanol, as the other biofuels, were exempted of both, the CO2 and energy taxes until 2009, resulting in a 30% price reduction at the pump of E85 fuel over gasoline. Furthermore, other demand side incentives for flexifuel vehicle owners include a financial bonus to buyers of FFVs, exemption from the Stockholm congestion tax, up to 20% discount on auto insurance, free parking spaces in most of the largest cities, lower annual registration taxes, and a 20% tax reduction for flexifuel company cars. Also, a part of the program, the Swedish Government ruled that 25% of their vehicle purchases (excluding police, fire and ambulance vehicles) must be alternative fuel vehicles.;[75][75][77] By the first months of 2008, this package of incentives resulted in sales of flexible-fuel cars representing 25% of new car sales.[75]

China is promoting ethanol-based fuel on a pilot basis in five cities in its central and northeastern region, a move designed to create a new market for its surplus grain and reduce consumption of petroleum. The cities include Zhengzhou, Luoyang and Nanyang in central China's Henan province, and Harbin and Zhaodong in Heilongjiang province, northeast China. Under the program, Henan will promote ethanol-based fuel across the province by the end of this year. Officials say the move is of great importance in helping to stabilize grain prices, raise farmers' income and reducing petrol- induced air pollution.[81]
Thailand already uses 10% ethanol (E10) on a large scale in the local market. Beginning in 2008 Thailand started with the sale of E20 and by late 2008 E85 flexible fuel vehicles were introduced with only two gas stations selling E85.[82]
Thailand is now converting some of the cassava stock held by the government into fuel ethanol. Cassava-based ethanol productions are being ramped up to help manage the agricultural outputs of both cassava and sugar cane. With its abundant biomass resources, it is believed that the fuel ethanol program will be a new means of job creation in the rural areas while enhancing the balance sheet of fuel imports.
Legislation in Australia imposes a 10% cap on the concentration of fuel ethanol blends. Blends of 90% unleaded petrol and 10% fuel ethanol are commonly referred to as E10. E10 is available through service stations operating under the BP, Caltex, Shell and United brands as well as those of a number of smaller independents. Not surprisingly, E10 is most widely available closer to the sources of production in Queensland and New South Wales where Sugar Cane is grown. E10 is most commonly blended with 91 RON "regular unleaded" fuel. There is a requirement that retailers label blends containing fuel ethanol on the dispenser.
Due to ethanol's greater stability under pressure it is used by Shell in their 100 octane fuel. Similarly IFS add 10% ethanol to their 91 octane fuel, label it premium fuel and sell it more cheaply than regular unleaded. This is converse to the general practice of adding ethanol to a lesser quality fuel to bring its octane rating up to 91.
Some concern was raised over the use of ethanol blend fuels in petrol vehicles in 2003, yet manufacturers widely claimed that their vehicles were engined for such fuels. Since then there have been no reports of adverse affects to vehicles running on ethanol blended fuels.

All countries in Central America, northern South America and the Caribbean are located in a tropical zone with suitable climate for growing sugar cane. In fact, most of these countries have a long tradition of growing sugar cane mainly for producing sugar and alcoholic beverages.
As a result of the guerrilla movements in Central America, in 1983 the United States unilateral and temporarily approved the Caribbean Basin Initiative, allowing most countries in the region to benefit from several tariff and trade benefits. These benefits were made permanent in 1990 and more recently, these benefits were replaced by the Caribbean Basin Trade and Partnership Act, approved in 2000, and the Dominican Republic–Central America Free Trade Agreement that went to effect in 2008. All these agreements have allowed several countries in the region to export ethanol to the U.S free of tariffs.[16] Until 2004, the countries that benefited the most were Jamaica and Costa Rica, but as the U.S. began demanding more fuel ethanol, the two countries increased their exports and two others began exporting. In 2007, Jamaica, El Salvador, Trinidad & Tobago and Costa Rica exported together to the U.S. a total of 230.5 million gallons of ethanol, representing 54.1% of U.S. fuel ethanol imports. Brasil began exporting ethanol to the U.S. in 2004 and exported 188.8 million gallons representing 44.3% of U.S. ethanol imports in 2007. The remaining 1.6% imports that year came from Canada and China.[30]
In March 2007, "ethanol diplomacy" was the focus of President George W. Bush's Latin American tour, in which he and Brazil's president, Luiz Inacio Lula da Silva, were seeking to promote the production and use of sugar cane based ethanol throughout Latin America and the Caribbean. The two countries also agreed to share technology and set international standards for biofuels.[83] The Brazilian sugar cane technology transfer would allow several Central American, Caribbean and Andean countries to take advantage of their tariff-free trade agreements to increase or become exporters to the United States in the short-term.[84] Also, in August 2007, Brazil's President toured Mexico and several countries in Central America and the Caribbean to promote Brazilian ethanol technology.[85] The ethanol alliance between the U.S. and Brazil generated some negative reactions from Venezuela's President Hugo Chavez,[86] and by then Cuba's President, Fidel Castro, who wrote that "you will see how many people among the hungry masses of our planet will no longer consume corn." "Or even worse," he continued, "by offering financing to poor countries to produce ethanol from corn or any other kind of food, no tree will be left to defend humanity from climate change."'[87] Daniel Ortega, Nicaragua's President, and one of the preferencial recipients of Brazilian technical aid also voiced critics to the Bush plan, but he vowed support for sugar cane based ethanol during Lula's visit to Nicaragua.[88][89]
Colombia's ethanol program began in 2002, based on a law approved in 2001 mandating a mix of 10% ethanol with regular gasoline, and the plan is to gradually reach a 25% blend in twenty-years. Sugar cane-based ethanol production began in 2005, when the law went into effect, and as local production was not enough to supply enough ethanol to the entire country's fleet, the program was implemented only on cities with more than 500,000 inhabitants, such as Cali, Pereira, and the capital city of Bogotá. All of the ethanol production comes from the Department of Valle del Cauca, Colombia's traditional sugar cane region. Cassava is the second source of ethanol, and potatoes and castor oil are also being studied.[90]
On March 2009 the Colombian government enacted a mandate to introduce E85 flexible-fuel cars. The executive decree applies to all gasoline-powered vehicles with engines smaller than 2.0 liters manufactured, imported, and commercialized in the country beginning in 2012, mandating that 60% of such vehicles must have flex-fuel engines capable of running with gasoline or E85, or any blend of both. By 2014 the mandatory quota is 80% and it will reach 100% by 2016. All vehicles with engines bigger than 2.0 liters must be E85 capable starting in 2013. The decree also mandates that by 2011 all gasoline stations must provide infrastructure to guarantee availability of E85 throughout the country.[91] The mandatory introduction of E85 flex-fuels has been controversial.[92][93]
The government, based on the National Biofuel Program, established the mandatory use of all gasoline sold in Costa Rica with a blend of around 7.5% ethanol, starting in October 2008. The implementation phase follows a two year trial that took place in the provinces of Guanacaste and Puntarenas. The government expects to increase the percentage of ethanol mixed with gasoline to 12% in the next 4 to 5 years. The Costa Rican government is pursuing this policy to lower the country's dependency of foreign oil and to reduce the amount of greenhouse gases produced. The plan also calls for an increase in ethanol producing crops and tax breaks for flex-fuel vehicles and other alternative fuel vehicles.[94] The introduction of the blend of 7% ethanol was postponed in September 2008 until the beginning of 2009. This delay was due to a request by the national association of fuel retailers to have more time available to adapt their fueling infrastructure.[95] Additional delays caused another postponement, as fueling stations were not ready yet for handling ethanol fuel, and now implementation is expected for November 2009.[96][97]
Despite the official postponement, during the months of February and March 2009, ethanol in different blends was sold without warning to consumers, which was cause for complains. The national distribution company, RECOPE, explained that it had already bought 50,000 barrels (7,900 m3) of ethanol stored and ready for distribution, so it decided to used as an oxygenate in substitution of MTBE. Nevertheless, retail sales of E7 continue uninterrupted in the trial regions of Guanacaste and the Central Pacific for three years now.[98]
As a result of the cooperation agreement between the United States and Brazil, El Salvador was chosen in 2007 to lead a pilot experience to introduce state-of-the-art technology for growing sugar cane for production of ethanol fuel in Central America, as this technical bilateral cooperation is looking for helping Central American countries to reduce their dependence on foreign oil.[99]
Brazil's sugar cane-based industry is far more efficient than the U.S. corn-based industry. Brazilian distillers are able to produce 1 liter of ethanol for from $0.19 to $0.24 (or from $0.71 to $0.90 per gallon), compared with the $0.41 to $0.46 cents per liter for corn-based ethanol (or $1.55 to $1.74 per gallon).[101] Sugarcane cultivation requires a tropical or subtropical climate, with a minimum of 600 mm (24 in) of annual rainfall. Sugarcane is one of the most efficient photosynthesizers in the plant kingdom, able to convert up to 2% of incident solar energy into biomass. Ethanol is produced by yeast fermentation of the sugar extracted from sugar cane.
Sugarcane production in the United States occurs in Florida, Louisiana, Hawaii, and Texas. In prime growing regions, such as Hawaii, sugarcane can produce 20 kg for each square meter exposed to the sun. The first three plants to produce sugar cane-based ethanol are expected to go online in Louisiana by mid 2009. Sugar mill plants in Lacassine, St. James and Bunkie were converted to sugar cane-based ethanol production using Colombian technology in order to make possible a profitable ethanol production. These three plants will produce 100 million gallons of ethanol within five years.[102]
U.S. corn-derived ethanol costs 30% more because the corn starch must first be converted to sugar before being distilled into alcohol. Despite this cost differential in production, in contrast to Japan and Sweden, the U.S. did not import much of Brazilian ethanol because of U.S. trade barriers corresponding to a tariff of 54-cent per gallon – a levy designed to offset the 45-cent per gallon blender's federal tax credit that was applied to ethanol no matter its country of origin.[6][103][104][105] In 2011 the U.S. Congress decided not to extend the tariff and the tax credit, and as a result both ended on December 31, 2011. Since 1980 the U.S. ethanol industry was awarded an estimated US$45 billion in subsidies.[106] One advantage U.S. corn-derived ethanol offers is the ability to return 1/3 of the feedstock back into the market as a replacement for the corn used in the form of Distillers Dried Grain.[22]
