Brazil Launches E32 Gasoline Policy, Ethanol Blend Rises to 32%, 180-Day Trial Begins

Brazil officially implemented its policy mandating a 32% blend of anhydrous ethanol in gasoline (E32) starting August 1. The new measure will initially run for 180 days and may be extended once for up to another 180 days depending on outcomes. The Brazilian National Agency of Petroleum, Natural Gas, and Biofuels (ANP) stated that this action follows a government resolution made earlier this month, raising the mandatory ethanol blend from 30% to 32% to enhance energy security, reduce dependence on gasoline imports, and further promote the domestic biofuel industry.

The E32 policy was approved in July by Brazil's National Energy Policy Council (CNPE). Officials stated that increasing the ethanol blend ratio is expected to reduce Brazil's annual gasoline imports by approximately 900 million liters. Amid ongoing global energy market volatility due to geopolitical tensions and oil price fluctuations, the move aims to reduce reliance on fossil fuels and strengthen energy autonomy.

The Brazilian government noted that tests indicate E32 fuel performs similarly to current fuel formulations in terms of vehicle performance and usability. As a result, the policy will be introduced as a temporary 180-day measure. If implementation proceeds smoothly, it may be extended by another 180 days and could serve as a foundation for future increases in ethanol blending ratios.

The policy is expected to directly boost demand for ethanol in Brazil. As one of the world's largest producers of sugarcane ethanol, Brazil has also seen rapid expansion in corn-based ethanol production in recent years. Authorities anticipate that the new policy will stimulate investment in both sugarcane and corn ethanol industries, further solidifying Brazil's position as a global leader in biofuels.

Industry groups such as the Brazilian Sugarcane Industry Association (UNICA) and the National Union of Corn Ethanol Producers (UNEM) have expressed support for the policy. They view E32 as a transitional step, with potential to eventually increase blending to 35% (E35), further raising the share of renewable energy in the fuel mix.

However, the new policy has also drawn opposition. Fuel importers and some fuel distributors worry that higher ethanol content could increase maintenance costs and affect performance in non-flex-fuel vehicles. Additionally, Brazil's Federal Public Prosecutor's Office (MPF) has filed a lawsuit seeking to suspend the E32 policy, introducing legal uncertainty around the measure.

In fact, Brazil has been steadily increasing its use of biofuels in recent years. In 2025, the country raised the ethanol blend in gasoline from 27% to 30% and simultaneously increased the biodiesel blend in diesel. The latest increase to 32% reflects the government's ongoing efforts to reduce oil dependence, promote decarbonization, and advance energy transition.

Analysts point out that amid persistent geopolitical risks, supply chain disruptions, and oil price volatility, Brazil's move to increase ethanol use not only reduces gasoline import demand but also helps stabilize domestic fuel supply while boosting the sugarcane and corn-based biofuel sectors. The outcomes of the 180-day trial and court rulings on related litigation will be key indicators of whether Brazil moves toward even higher ethanol blending ratios in the future.
