Ethanol producing countries defined Fuel ethanol — ethyl alcohol blended into gasoline — is produced in over 50 countries, but two dominate the world market: the United States and Brazil together account for approximately 83% of global output. The US produces ethanol from corn under the Renewable Fuel Standard; Brazil produces it from sugarcane under a long-standing blending mandate. India is the fastest-growing major producer, tripling output between 2020 and 2024. Feedstock determines efficiency: sugarcane ethanol is 5-6 times more energy-efficient per acre than corn ethanol.

Global Production Rankings
| Country | Production (billion litres, approx. 2023) | Share of Global Output | Primary Feedstock |
|---|---|---|---|
| USA | ~57 | ~54% | Corn (maize) |
| Brazil | ~35 | ~29% | Sugarcane |
| EU (27 countries) | ~6 | ~5% | Wheat, sugar beet, corn |
| India | ~5 | ~4% | Sugarcane, rice, corn |
| China | ~4 | ~3% | Corn, cassava, sorghum |

| Rest of world | ~5 | ~3.3% | Various |
Total global production: approximately 115-120 billion litres per year (2023 data).
The US and Brazil together have produced more than 80% of global fuel ethanol for nearly two decades. This dominance is not coincidental — both countries built their industries deliberately through policy mandates, and both have large, efficient agricultural sectors producing cheap feedstocks.
The EU’s relatively small share is notable given the size of its economy. European ethanol production is held back by higher feedstock costs (European corn, wheat, and sugar beet are more expensive than US corn or Brazilian sugarcane) and by member state policy variation.
US Corn Ethanol: The Renewable Fuel Standard Engine
The US ethanol industry was built by policy. Before the mid-2000s, US ethanol production was minimal. Two policy changes transformed it.
The Energy Policy Act of 2005 established the first Renewable Fuel Standard (RFS), mandating minimum volumes of renewable fuels in the US gasoline supply. The Energy Independence and Security Act of 2007 expanded the RFS substantially — the Renewable Fuel Standard 2 (RFS2) required 36 billion gallons of renewable fuels by 2022, with 15 billion gallons to come from conventional biofuels (mainly corn ethanol).
The effect was dramatic. US corn ethanol production grew from about 4 billion gallons in 2005 to over 15 billion gallons by 2010. Today it runs at around 15-16 billion gallons (~57-60 billion litres) per year, consuming approximately 35% of the entire US corn crop.
How US corn ethanol is made: Corn grain is ground, mixed with water, and cooked to release starch. Enzymes convert the starch to sugars. Yeast ferments the sugars to ethanol. The ethanol is distilled and dehydrated to fuel-grade purity (99.9%). The residue — DDGS (dried distillers grains with solubles) — is a protein-rich animal feed sold domestically and exported.
The corn-ethanol price link: US ethanol production economics are directly tied to the price of corn (the feedstock), the price of natural gas (used to dry grain and power the plant), and the price of ethanol itself. When corn is expensive relative to ethanol, ethanol plant margins are squeezed and some plants curtail production. This corn-ethanol-margin relationship is tracked closely by CBOT traders.
Blend rate: US gasoline contains 10% ethanol (E10) as the standard blend. Some markets offer E15 (15% ethanol) and E85 (85% ethanol for flex-fuel vehicles). The “blend wall” — the practical limit of ethanol consumption given the standard 10% blend rate and total gasoline demand — has been a persistent policy tension.
Brazil Sugarcane Ethanol: The Most Efficient Producer
Brazil’s ethanol programme is the oldest and most mature in the world. It began in 1975 with the Proálcool (National Alcohol Programme), launched in response to the 1973 oil crisis. For over 50 years, Brazil has been blending sugarcane ethanol into its gasoline.
Sugarcane advantage: Brazilian sugarcane ethanol produces approximately 8,000-9,000 litres of ethanol per hectare per year. US corn ethanol produces approximately 3,800-4,000 litres per hectare per year. Sugarcane is 5-6 times more energy-efficient per unit of land area than corn, and its energy balance (energy output per unit of fossil fuel input) is approximately 8:1 versus 1.4-2:1 for corn ethanol.
How Brazilian sugarcane ethanol is made: Sugarcane is crushed to extract juice, which is directly fermented by yeast. The bagasse (crushed cane fibre) is burned to generate electricity that powers the mill, making Brazilian sugarcane mills largely energy self-sufficient. The ethanol is distilled to fuel grade and either blended into gasoline at the refinery gate or sold as hydrous ethanol (E100) directly at fuel pumps.
Brazil’s blending mandate: The RenovaBio policy (enacted 2017) and the mandatory blend rate — currently 27% ethanol in gasoline (E27) — ensure a large domestic market for ethanol. Brazil also has flex-fuel vehicles, which run on any ratio of gasoline to ethanol. Over 85% of new passenger cars sold in Brazil are flex-fuel. This means Brazilian consumers choose between gasoline and hydrous ethanol based on the price at the pump.
The cane/sugar split: Brazilian sugarcane mills can switch production between sugar and ethanol based on relative prices. When sugar is expensive, mills divert more cane to sugar production. When ethanol is expensive relative to sugar, they produce more ethanol. This flexibility creates an important price linkage between global sugar prices and Brazilian ethanol output.
EU Ethanol: Wheat, Beet, and the Mandate
The EU’s fuel ethanol industry operates under the Renewable Energy Directive (RED, now RED II and RED III), which sets overall renewable energy targets and imposes blending mandates through member state national action plans.
EU ethanol is predominantly produced from:
- Wheat: France, Germany, Belgium, and the Netherlands produce wheat-based ethanol
- Sugar beet: A co-product alongside sugar production from sugar beet in France, Germany, and Belgium
- Corn: Eastern European producers (Hungary, Romania, Slovakia) use corn
The EU produces approximately 5-6 billion litres per year — enough for roughly a 5-6% blend share in the EU’s total gasoline pool.
Cost disadvantage: European feedstocks are significantly more expensive per tonne than US corn or Brazilian sugarcane. EU wheat ethanol typically costs €0.55-0.75/litre to produce, versus US corn ethanol at around $0.35-0.45/litre. This cost gap has limited investment in EU ethanol capacity and made EU producers dependent on blending mandates rather than being price-competitive.
RED III changes: The revised Renewable Energy Directive (RED III, agreed 2023) sets a 29% renewable energy share in transport by 2030 and caps the contribution of food and feed crop-based biofuels at 7% of final energy in transport. This cap limits the growth of conventional first-generation ethanol (from food crops) and pushes toward advanced biofuels from waste and residues.
India: The Fastest-Growing Ethanol Producer
India is the most significant growth story in global ethanol. Production roughly tripled between 2020 and 2024, rising from approximately 1.7 billion litres to around 5 billion litres.
This growth was driven by the Indian government’s Ethanol Blending Programme (EBP), which set a target of 20% ethanol blending in petrol by 2025 (subsequently adjusted to 2025-26). Progress:
- 2019-20 blending season: 5.0% blend rate
- 2021-22: 8.9%
- 2022-23: 11.5%
- 2023-24: approximately 14-15%
India uses sugarcane-based feedstocks primarily — sugarcane juice and B-heavy molasses (a by-product of sugar production). Corn-based ethanol capacity is expanding rapidly under new government approvals.
Why India’s growth matters for global markets: India’s rapid expansion of domestic ethanol consumption is reducing its need for imported fuel and creating new domestic demand for sugarcane and corn. It has also prompted some bilateral discussions about ethanol trade — India has occasionally imported Brazilian sugarcane ethanol when domestic supplies were tight.
Policy risk: India’s ethanol blending programme is deeply linked to its sugar sector policy. When sugar production is low (during drought years affecting the sugarcane crop), the government has diverted fewer resources from sugar to ethanol, slowing blending progress. Sugarcane price support policies and sugar export controls also affect how much cane is diverted to ethanol.
China: Large Producer, Domestic Focus
China produces approximately 4 billion litres of fuel ethanol per year, mainly from corn, cassava, and sorghum. The industry operates under a mandatory 10% ethanol blending policy in selected provinces (rather than nationwide).
China’s ethanol programme has been notably unpredictable. In 2017, the government announced ambitious nationwide E10 by 2020. That target was subsequently softened and delayed as domestic corn prices rose and concerns about food security limited the policy appetite for diverting food grain to fuel.
China’s ethanol programme is therefore significant in scale but less reliable in growth trajectory than the US, Brazilian, or Indian programmes. Its domestic corn consumption for ethanol is a factor that US corn traders monitor, since Chinese domestic corn policy affects whether China imports US corn.
Feedstock Comparison: Why Different Countries Use Different Inputs
The choice of feedstock is driven by three factors: climate suitability, feedstock cost, and government policy.
| Feedstock | Main Countries | Litres Ethanol/Tonne | Energy Balance (output:input) | Cost Advantage |
|---|---|---|---|---|
| Sugarcane | Brazil, India, Thailand | ~70-90 litres | ~8:1 | Cheapest per litre produced |
| Sugar beet | EU (France, Germany) | ~100-110 litres | ~2-3:1 | Moderate |
| Corn | USA, China, Canada | ~380-400 litres/tonne | ~1.4-2:1 | Cheap in US; moderate elsewhere |
| Wheat | EU, Canada | ~360-380 litres/tonne | ~1.5-2:1 | Higher cost feedstock |
| Cassava | Thailand, China | ~150-170 litres/tonne | ~1.5-2:1 | Low cost in tropics |
Sugarcane is the most efficient ethanol feedstock. It contains sucrose that ferments directly without cooking — unlike starch-based feedstocks (corn, wheat, cassava) which require enzymatic conversion. Sugarcane also provides its own process energy through bagasse combustion. The limitation: sugarcane grows only in tropical and subtropical climates.
Corn ethanol dominates the US because: the US has vast corn production at low cost; the climate is unsuitable for sugarcane at commercial scale outside Florida; and political support from the Corn Belt farm lobby has been consistent since the 1970s.
Wheat ethanol in Europe reflects the availability of surplus wheat production and EU agricultural subsidy history rather than any inherent efficiency advantage.
Global Trade Flows: Who Exports, Who Imports
| Country | Trade Position | Key Destinations / Origins |
|---|---|---|
| USA | World’s #1 ethanol exporter | Brazil, India, EU, Canada, South Korea, UK |
| Brazil | World’s #2 ethanol exporter | EU, USA, South Korea, Japan |
| EU | Net importer (some member states) | Brazil, USA |
| India | Primarily domestic focus; occasional importer | Brazil (when domestic supply is short) |
| South Korea | Net importer | USA, Brazil |
| Japan | Net importer | Brazil, USA |
The US exports roughly 4-5 billion litres of fuel ethanol per year, primarily to Brazil (for re-blending into its flex-fuel system and for re-export), India, the EU, and Asia. The US has a competitive advantage in corn ethanol cost when corn is cheap.
Brazil exports 2-4 billion litres per year, primarily to the EU (which values sugarcane ethanol’s better carbon credentials under the Renewable Energy Directive’s sustainability criteria) and to Asia.
The Brazil-US ethanol relationship is unique: the two countries are both the world’s largest producers and each other’s largest export markets, as they have complementary seasonal production cycles (Brazil’s cane harvest peaks during its dry season, April-November; the US corn harvest runs September-November with ethanol production year-round).
Ethanol as a Commodity: CBOT Futures and Corn Price Correlation
CBOT ethanol futures (ticker: EH) are traded on the CME Group’s Chicago Board of Trade. The contract specifies denatured fuel ethanol delivered in Chicago.
Key specifications:
- Unit: 29,000 gallons (approximately 109,756 litres)
- Quotation: US cents per gallon
- Delivery months: All months
The most important price relationship in US ethanol is the corn-to-ethanol processing margin — also called the ethanol crush spread. This spread measures the profitability of buying corn, producing ethanol and DDGS, and selling both.
Simplified ethanol crush calculation:
- One bushel of corn (56 lbs) produces approximately 2.8 gallons of ethanol + 17 lbs of DDGS
- Crush margin = (2.8 × ethanol price) + (DDGS value) − corn price − operating costs
When this margin is positive, ethanol plants run at full capacity. When it turns negative, plants curtail production or sell forward-hedged positions to lock in existing margins.
Because corn comprises roughly 70% of an ethanol plant’s variable operating costs, corn futures (CBOT ZC) and ethanol futures (CBOT EH) are highly correlated. A spike in corn prices compresses ethanol plant margins. A fall in corn prices, or a rise in ethanol prices (typically driven by high gasoline prices), improves margins.
Gasoline/ethanol price relationship: In the US, ethanol price is strongly correlated with gasoline price because ethanol’s primary use is as a blend component. When gasoline prices rise (driven by crude oil), ethanol demand rises, pushing up ethanol prices. This creates a three-way correlation: crude oil → gasoline → ethanol → corn.
For commodity professionals who source corn or monitor energy costs, understanding this three-way correlation is important for forward price planning.
Frequently Asked Questions
Why does Brazil use sugarcane for ethanol instead of corn?
Brazil has a tropical climate suited to large-scale sugarcane cultivation and does not have the temperate climate required for large-scale corn production at US levels of yield. Sugarcane is also far more efficient: it produces 5-6 times more ethanol per acre than corn and requires less processing energy. Brazil has been developing its sugarcane ethanol industry since 1975, giving it 50 years of infrastructure, expertise, and policy framework. Corn would simply cost more per litre of ethanol in Brazil.
What is the Renewable Fuel Standard and how does it support US ethanol?
The Renewable Fuel Standard (RFS) is a US federal programme requiring a minimum volume of renewable fuels (including ethanol) to be blended into the US fuel supply each year. The EPA sets annual “Renewable Volume Obligations” for obligated parties (fuel refiners and blenders). This created a guaranteed minimum demand for corn ethanol that justified the massive investment in plant construction in the mid-2000s. Without the RFS mandate, US ethanol production would be significantly smaller.
Why is Indian ethanol production growing so fast?
India’s government set a target of 20% ethanol blending in petrol under its Ethanol Blending Programme (EBP). Achieving this required rapidly scaling domestic production. The government provided incentives for ethanol plant construction, set government-administered purchase prices for ethanol from oil companies, and introduced a tiered pricing system that encouraged production from different feedstocks. Production roughly tripled from 2020 to 2024 as a result. The programme is also part of India’s energy security strategy — reducing dependence on imported crude oil.
How do corn prices affect US ethanol economics?
Corn is approximately 70% of a US ethanol plant’s variable operating cost. When corn prices rise on the CBOT, ethanol plant margins are squeezed. If ethanol prices don’t rise proportionally (which depends on gasoline demand and blending economics), plants with locked-in corn purchases can lose money. Conversely, when corn prices fall, plant margins improve and production economics are attractive. The corn-ethanol crush spread is the standard measure of ethanol plant profitability, tracking this relationship continuously.
Can countries export ethanol freely?
Not always. Trade in fuel ethanol faces tariffs and technical barriers in some markets. Brazil and the US negotiated a tariff-free arrangement for a quota of Brazilian ethanol entering the US market. The EU applies a 6.5% import tariff on ethanol. India has intermittently restricted or encouraged imports depending on domestic supply. The technical barrier that most affects trade is the requirement for denatured versus anhydrous versus hydrous ethanol — specifications differ by country and not all grades can be used interchangeably.
What happens to ethanol plant co-products?
The main co-product of corn ethanol production is DDGS (dried distillers grains with solubles) — a high-protein animal feed. A standard corn ethanol plant produces approximately 17 pounds of DDGS per bushel of corn. The US exports significant volumes of DDGS to China, South Korea, Mexico, and other countries where it competes with soybean meal as a protein source. DDGS revenue is an important part of ethanol plant economics — the crush spread calculation includes DDGS value.
Key Takeaways
- The US and Brazil together produce approximately 83% of global fuel ethanol; the US uses corn under the Renewable Fuel Standard, Brazil uses sugarcane under long-standing blending mandates.
- Sugarcane is 5-6 times more energy-efficient per acre than corn for ethanol production, giving Brazil a fundamental cost and efficiency advantage.
- India is the fastest-growing major ethanol producer, roughly tripling output from 2020 to 2024 under its Ethanol Blending Programme targeting 20% blending by 2025-26.
- The EU produces ethanol from wheat and sugar beet at higher cost than US or Brazilian competitors, relying on the Renewable Energy Directive mandates rather than competitive production economics.
- CBOT ethanol futures (ticker EH) and CBOT corn futures (ZC) are strongly correlated — corn is ~70% of US ethanol plant variable costs, making corn price movements directly affect plant margins.
- The US is the world’s largest ethanol exporter; Brazil is second; both countries are also major export customers for each other, given complementary seasonal production cycles.
- The three-way correlation between crude oil prices, gasoline prices, and corn/ethanol prices means commodity professionals tracking any one of these markets need to understand all three.
- China produces significant volumes of ethanol but its policy programme has been inconsistent, making growth less predictable than in the US, Brazil, or India.
