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.

Natural Gas as a Pillar of Brazil’s Energy Security: Insights from Gas Week 2026

A comprehensive panel discussion on the impact of Brazil's Capacity Reserve Auction (LRCAP) on the natural gas market, recorded on the second day of the Gas Week 2026, organized by Eixos, highlighted the pivotal role of natural gas in the nation's energy matrix. With 90 projects and 15 GW of gas thermal plants contracted, the panel brought together key players including Eneva, Petrobras, Origem Energia, Cocal, and ED, alongside regulators EPE and ANP, to debate critical issues such as tariffs, LNG, storage, biomethane, and the future steps for the post-auction gas market.

Brazil’s recent capacity reserve auction has solidified the role of natural gas as a critical pillar for the country’s energy security, with major industry players securing key contracts to provide dispatchable power to a grid increasingly reliant on intermittent renewable sources.

The auction, held in March and conducted by ANEEL, MME, and CCEE, successfully contracted 18.97 GW of capacity — primarily from gas-fired thermal plants. The projects represent R$ 64.5 billion in total investments with delivery dates ranging from 2026 to 2031. The auction achieved a 5.52% discount, resulting in estimated savings of R$ 33.64 billion.

The results were the focus of intense discussion at the Gas Week 2026 conference in Brasília, where executives and regulators analyzed the long-term impacts on the nation’s energy and gas markets.

Eneva and Petrobras Secure Dominance

Eneva, the largest private natural gas producer in Brazil, emerged as a protagonist in the auction. Despite legal challenges and scrutiny from the Federal Audit Court (TCU), Executive Director of Marketing, Sales and New Business at Eneva, Marcelo Lopes, expressed confidence in the process.

"The auction was not designed to favor specific agents, but to contract the energy security the system needs," Marcelo stated during a panel. He noted that national energy planners (EPE) and the grid operator (ONS) have signaled the need for dispatchable power since 2021.

State-run oil giant Petrobras also secured significant re-contracting for its existing thermal fleet. Leonardo Santos Ferreira, a Petrobras Gas and Energy Marketing Manager, highlighted that the new contracts provide the fixed revenue necessary for infrastructure investments, with a renewed focus on "operational flexibility." This allows plants to be dispatched up to twice a day to balance the grid.

Market Volatility and New Frontiers

The auction is expected to transform the Brazilian gas market by treating gas as a "flexibility fuel." Flávia Barros, director of Origem Energia, noted that the intermittent demand from thermal plants would likely increase short-term price volatility, creating both risks and opportunities for traders.

"The winners in the post-auction market will be those capable of coordinating infrastructure and operating in a regionally fragmented environment," Flávia said, highlighting Origem’s strategy of integrating upstream production with strategic gas storage.

In a first for Brazil’s capacity auctions, Cocal successfully negotiated thermal projects powered by biomethane, signaling a shift toward replacing fossil fuels with renewable gas in the industrial and power sectors.

Regulatory and Infrastructure Outlook

The National Petroleum Agency (ANP) estimates that the auction results could lead to the contracting of 49 million cubic meters of gas per day. Pietro Mendes, an ANP director, emphasized that this volume is crucial for maintaining the financial health of the gas transport system and could help lower transport tariffs in the long run.

Heloisa Borges, Director at the Energy Research Office (EPE), concluded that the Brazilian gas industry has reached a level of maturity capable of delivering diversified solutions, including LNG, domestic gas, and pipeline imports.

"We saw a robust industry capable of responding to the different needs of various actors," Borges said, pointing to the upcoming Integrated National Infrastructure Plan as the next step in supporting Brazil's growing gas production.
