From Sugarcane to Gas Tank: Brazil’s 32% Ethanol Blend Set to Transform Biofuel Market

Brazilian President Luiz Inácio Lula da Silva is set to authorize an increase in the mandatory ethanol blend in gasoline from 30% to 32%, a move aimed at curbing fuel imports and enhancing national energy security amid global oil market volatility driven by the conflict between Iran and the United States.

The proposal, which could be signed as early as this week during an extraordinary meeting of the National Energy Policy Council (CNPE), is expected to eliminate Brazil’s reliance on imported gasoline. Despite being a major oil producer, Brazil currently imports between 10% and 15% of its gasoline due to domestic refining bottlenecks.

Boosting Demand and Local Production

The shift to a 32% anhydrous ethanol blend (E32) is projected to increase annual demand for the biofuel by approximately 1 billion liters, according to UNICA, the industry association representing sugarcane and ethanol producers.

Industry leaders expressed optimism, noting that Brazil is heading toward a record harvest. National supply agency Conab recently revised its production estimates upward, forecasting a 5.3% increase in the current harvest that began in April.

"We have total capacity to meet this demand," said a representative from the sugarcane industry. "In addition to consumer and environmental benefits, Brazilian ethanol generates jobs and income in both rural and urban areas."

Technical Readiness vs. Consumer Concerns

Minister of Mines and Energy Alexandre Silveira stated that technical tests have already confirmed the safety and viability of the E32 blend for vehicle engines. However, the move has faced some pushback from automotive sectors.

While the government maintains that engines are ready, some critics and industry groups, including the motorcycle manufacturers' association Abraciclo, have raised concerns. Reports suggest that higher ethanol concentrations could lead to ignition issues in colder temperatures and potential long-term compatibility problems that have not been fully vetted.

Market Adjustment and Increased Demand

The blend expansion is also expected to have a direct impact on anhydrous ethanol consumption. According to Martinho Seiiti Ono, CEO of SCA Brasil Etanol, E32 could increase biofuel demand by about 850 million liters per year. This surge in demand comes as production is estimated to grow by over 4 billion liters this harvest, including both sugarcane and corn ethanol. In this context, the higher blend serves as a mechanism to absorb surplus supply, ensuring market equilibrium.

The measure is also expected to reduce price volatility throughout the cycle and improve conditions for consumers, while providing greater predictability for ethanol contract renewals for the 2026/27 harvest. Furthermore, it is anticipated to boost the competitiveness of hydrous ethanol by altering the traditional 70% price parity threshold.

Beyond economic impacts, E32 reinforces Brazil's position in the global decarbonization agenda. The measure aligns with the "Fuel of the Future" program, which envisions a gradual increase in the blend up to 35% and paves the way for new frontiers, such as Sustainable Aviation Fuel (SAF) and renewable bunker fuel.

Global Market Impact

The announcement has already reverberated through international commodity markets. As Brazilian mills pivot to produce more anhydrous ethanol to meet the new mandate, global sugar prices have seen a slight recovery. Analysts suggest that Brazil’s sugar production could drop to 37 million tonnes — down from previous estimates of 40 million — as more sugarcane is diverted to biofuel production.

The policy is part of a broader "Fuel of the Future" strategy, which also envisions increasing the biodiesel blend in diesel to 16% this year, with a target of 20% by 2030, pending further technical testing.

Brazil’s Ethanol Power Play: How Sugarcane and Corn are Shielding the Economy from a Global Oil Shock

Brazil's long-standing ethanol program is proving to be a crucial buffer against rising global oil prices, particularly as the conflict involving Iran, the United States, and Israel enters its fifth week. Nations like India and Mexico are now examining Brazil's energy security model as a potential blueprint.

The South American giant is partially shielded from international oil market volatility by its decades-old, cost-effective, and environmentally friendly ethanol initiative. Millions of Brazilian motorists have the option to fuel their vehicles with 100% sugarcane-derived ethanol or a gasoline blend containing 30% biofuel.

Brazil's extensive fleet of flex-fuel vehicles, capable of running on any combination of ethanol and gasoline, is unparalleled globally. The program Proálcool (Programa Nacional do Álcool), initiated in 1975, has successfully evolved to reduce the country's reliance on foreign oil.

While consumers worldwide grapple with significant price hikes, gasoline prices in Brazil saw a modest 5% increase in March, starkly contrasting the 30% surge observed in the United States. Analysts attribute this stability to Brazil's mature domestic biofuel industry, which enables the nation to absorb geopolitical shocks with minimal risk of fuel shortages.

Evandro Gussi, president of the Brazilian Sugarcane Industry Association (UNICA), emphasized that Brazil is "much better prepared than most countries" due to this viable alternative. The upcoming sugarcane harvest, set to commence in early April, is projected to yield a record 30 billion liters of ethanol, a 4 billion liter increase from the previous year. Gussi noted that this additional volume alone is equivalent to Brazil's total gasoline imports for the entirety of last year.

Despite being a significant crude oil producer and exporter, Brazil remains dependent on imports for refined fuels, sourcing from countries including the United States, Saudi Arabia, Russia, and neighboring Guyana. Nevertheless, ethanol has become integral to daily transportation, with 37.1 billion liters sold in 2025, according to the state-owned Energy Research Company (EPE). Its widespread availability provides Brazilians with both psychological and economic reassurance.

Research and Development

The success of Brazil's biofuel economy is deeply rooted in São Paulo, the country's industrial and agricultural heartland. Production methods encompass both high-tech, export-oriented 'megafarms' and smaller, family-run operations. State-funded research, exemplified by the Unicamp Ethanol Scientific Development Center in Campinas, also plays a pivotal role in advancing Brazilian biofuel technology. Luis Cortez, the center's coordinator, underscored the unique advantages of Brazil's program, asserting that investment in research ultimately translates into tangible benefits at the fuel pumps.

Diesel Sector Challenges

While the potential closure of the Strait of Hormuz has not significantly impacted Brazil's gasoline market, the nation faces considerable challenges with escalating diesel prices. Diesel is predominantly produced from imported crude oil and incorporates a smaller proportion of biofuels. Brazilian biodiesel, primarily derived from soybeans, constitutes only 14% of the diesel blend. This percentage is not expected to reach 30% until 2030, implying an immediate impact from the ongoing conflict.

Brazilian diesel prices climbed over 20% in March, prompting President Luiz Inácio Lula da Silva to propose import subsidies until May. Government estimates suggest Brazil needs to import between 20% and 30% of its monthly diesel requirements, with the majority originating from Russia. Brazilian authorities reported nearly 17 billion liters of diesel imported last year. For President Lula, who is seeking re-election in October, stabilizing diesel prices is paramount to avert trucker strikes and mitigate food inflation.

Rabobank calculations indicate that increasing the anhydrous ethanol blend in gasoline from the current 30% to 32%, a measure advocated by some segments of the sugar-energy sector, could displace 1.2 billion liters of gasoline over a 12-month period. This would effectively substitute 34% of fossil fuel imports, considering Brazil imported 3.5 billion liters of gasoline A last year. However, such a modification is contingent upon technical tests, which the Ministry of Mines and Energy (MME) is currently facilitating. Industry leaders anticipate that an increased blend would only be feasible next year.

Should an increased ethanol blend be implemented sooner, it would also permit a rise in hydrous ethanol prices (which compete with gasoline at the pumps) relative to fossil fuels. Hydrous ethanol prices are typically discounted against gasoline due to its lower energy yield, generally hovering around 70% — a level that fluctuates with biofuel supply. Rabobank estimates that an increase in the anhydrous ethanol blend to 32% would reduce the hydrous ethanol price discount by 2%.

Presently, gasoline maintains a 30% anhydrous ethanol content, and its average pump price in Brazil rose 6% in March amidst speculation surrounding the Middle East conflict's repercussions. This occurred despite Petrobras not increasing the price of gasoline A sold at its refineries. The state-owned company accounts for 80% of the country's gasoline A supply capacity.

Recent Investments in Biofuels

On March 25, Grupo Potencial, a conglomerate with interests in energy, fuels, and agribusiness, announced a significant investment of BRL 6 billion ($1.2 billion USD) by 2030. Carlos Eduardo Hammerschmidt, the company's Vice-President for Commercial, Institutional Relations, and New Investments, stated that the objective is to further develop their integrated supply chain model and expand operations within a rapidly growing market. The group is already a prominent player, holding the title of Latin America's largest single-plant biodiesel producer, with an annual capacity nearing 1 billion liters. Approximately 15% of all soybeans cultivated in Paraná are processed, directly or indirectly, by the company. In 2025, Grupo Potencial's revenue increased by 15% to BRL 12 billion ($2.4 billion USD), with new investments projected to boost revenue to BRL 20 billion ($4 billion USD) within four years.

In another development, RRP Energia, a subsidiary of Grupo Piccini, secured BRL 1 billion ($200 million USD) in financing from BNDES (National Bank for Economic and Social Development) for the construction of a corn ethanol plant in Tapurah, Mato Grosso. The new facility will have the capacity to produce up to 459 million liters of hydrous ethanol or 452 million liters of anhydrous ethanol annually. Additionally, it will process over 1 million tons of corn each year, yielding valuable by-products such as animal feed ingredients and corn oil. The BNDES credit covers more than 60% of the project's total investment, structured as a long-term loan with the bank serving as the primary financier. The funding originates from the Climate Fund and the BNDES Finem line, qualifying the project due to its association with renewable fuel production and its potential to substitute fossil fuel sources.

Brazil's Biofuel Ascendancy: Embraer's (EMBR3) Ethanol Aircraft Goes Global as Corn Drives Domestic Energy Shift

A strategic move to internationalize the Ipanema crop duster, coupled with a structural boom in corn-based ethanol production, solidifies Brazil's leadership in sustainable energy.

Brazil is reinforcing its status as a global bioenergy powerhouse through a dual strategy of technological export and domestic production innovation. On one front, aerospace giant Embraer is taking its first concrete steps to internationalize its successful ethanol-powered agricultural aircraft, the Ipanema. Simultaneously, the nation's bioenergy matrix is undergoing a structural transformation, with corn-based ethanol production surging to historic levels, attracting significant investment, and bolstering national energy security.

Embraer's Biofuel Ambition Takes Flight

The internationalization effort centers on the Ipanema, a crop duster that has been exclusively powered by biofuel since 2015. Embraer recently signed a memorandum of understanding with Essential Energy Holding, an Argentine ethanol producer, to explore market opportunities in Argentina's key agricultural regions, such as northern Santa Fe province. This partnership is a crucial step in overcoming the primary barrier to the Ipanema's foreign expansion: the lack of a widely distributed and abundant ethanol supply outside Brazil.

Embraer's director of agricultural aviation business and production, Sany Onofre, noted that the lack of fuel availability had previously made expansion into Latin America "a difficulty, or even an impossibility." To address this, the company has engaged with industrial associations and potential partners across the region, including in Paraguay, Uruguay, and Mexico, finding them "extremely enthusiastic."

Initially conceived to offer farmers a cost-effective alternative, ethanol being cheaper than gasoline, the Ipanema has increasingly gained a strong environmental appeal due to its lower carbon footprint. Essential Energy CEO Federico Pucciariello noted that the collaboration aims to "improve the economic equation for Argentine producers by facilitating access to cutting-edge technology and locally produced ethanol, which translates into lower operating costs and higher productivity in the field."

The market potential is significant. While Embraer's agricultural aviation unit currently generates around US$60 million annually, the company estimates that the opening of Latin American markets could boost the segment's revenue by 20% to 30%. The groundwork is already being laid, with a recent Ipanema sale to a rural producer in Paraguay, which quickly led to nationwide operational approval for the aircraft. In Argentina, Embraer is currently awaiting regulatory clearance for operational authorization.

Competing Landscape

Despite the growing presence of agricultural drones, Embraer does not yet view them as direct competitors. "They are smaller-capacity products designed for specific tasks," Onofre explained. An Ipanema carries up to 700 kilograms per flight, whereas the largest spraying drones currently carry around 50 kilograms. However, the company remains vigilant, acknowledging that "larger drones and unmanned aerial vehicles [are] under development, and we will encounter them along the way."

The Corn Ethanol Revolution

The second major development underscoring Brazil's bioenergy leadership is the structural shift in its domestic ethanol production. Corn-based ethanol has surged, gaining a central role in the country’s biofuels matrix and attracting new investments.

In a historic milestone, corn ethanol accounted for 77.2% of total ethanol production during the second half of December 2025, according to data from the Brazilian Sugarcane and Bioenergy Industry Association (Unica). This figure reflects the strong momentum of the 2025/26 harvest and sustained investment flows into the sector.

The rapid growth of corn ethanol marks a significant change in an industry historically dominated by sugarcane. Corn-based production offers a key advantage: operational predictability, allowing plants to operate year-round and reducing dependence on agricultural seasonality.

During the 2025/26 harvest, corn ethanol production reached 6.86 billion liters, representing a 13.98% increase compared to the same period of the previous season. This expansion is supported by technological advances, improved energy efficiency, and the integration of valuable co-products.

Strengthening Energy Security and Regional Development

The expansion of corn ethanol reinforces the strategic role of bioenergy in Brazil’s energy matrix. By increasing the supply of renewable fuels, the country reduces its exposure to international oil price volatility and geopolitical risks. This diversification aligns Brazil with global climate goals and decarbonization commitments.

The growth trajectory is closely linked to rising investments in new plants and capacity expansions. The continuous production throughout the year reduces financial risk, making the sector increasingly attractive to private capital. Furthermore, the integration of ethanol production with power generation and co-products, such as DDG (distillers dried grains) used in animal nutrition, enhances project profitability and strengthens synergies across the agriculture, livestock, and energy sectors.

Beyond the energy industry, this expansion generates jobs, stimulates local economies, and strengthens agribusiness value chains, with municipalities hosting ethanol plants benefiting from increased tax revenues and broader economic activity.

The simultaneous push by Embraer to export its ethanol-powered technology and the domestic surge of corn ethanol production illustrate a mature and dynamic Brazilian bioenergy sector. By combining technological innovation with a structural shift in production, Brazil is not only securing its own energy future but also positioning itself as a global leader in the transition to sustainable, low-carbon energy sources. The next phase for the industry will involve successfully replicating the ethanol infrastructure abroad while continuing to maximize the efficiency and economic benefits of its diversified domestic production.
