Biofuels in Brazil: Ethanol to Sustainable Aviation Fuel (SAF) Explained (2025)

Brazil's biofuel sector is a powerhouse, with decades of supportive policies and a thriving agricultural industry driving large-scale adoption of low-carbon fuels in its transport sector. The country is the world's second-largest ethanol producer and third-largest biodiesel producer. However, the industry faces both headwinds and tailwinds in the coming decades, including a potential increase in domestic blending mandates and a reduction in ethanol demand for road transport due to rising electrification.

Controversy & Comment Hooks: The potential to be a global supplier of advanced low-carbon fuels, such as sustainable aviation fuel (SAF), could represent an important economic opportunity for Brazil. But here's where it gets controversial: a significant increase in SAF demand will depend heavily on policy and economic incentives, as SAF comes with considerably higher costs than its fossil-based counterpart. Even the United Nations' regulating body for aviation (Corsia) is unlikely to spur significant SAF demand, as the low price of carbon credits makes these a far more cost-effective alternative to adopting SAF at scale.

Controversy & Comment Hooks: Brazilian SAF production could face export challenges. Food-crop feedstocks, such as sugarcane and soy, face policy exclusions or reduced economic incentives in major SAF markets such as the EU and the US. The combined capacity of announced projects in Brazil is likely to represent a small share of global supply, with the 10 announced plants projected to produce about 700 million liters per year by 2030, representing just 2% of global SAF supply or 9% of total domestic jet fuel demand.

Controversy & Comment Hooks: Despite these challenges, the sheer scale of Brazil's agricultural sector and its agronomic advantages represent opportunities. A 48% decline in deforestation since 2021, an increase in double-cropping practices (e.g., between soy and corn), and initiatives to restore degraded areas could all help Brazil become more competitive than other biofuel-producing nations. These attributes could, for example, reduce emissions related to land use and land-use change in Corsia's carbon intensity calculations for most crops, while also alleviating pressures on global land requirements for food and fiber versus biofuel crops.

Controversy & Comment Hooks: An advanced low-carbon fuel industry could strengthen Brazil's exports and protect it from global trade disputes. Agricultural commodities are often used as leverage, as seen in the recent shift in Chinese soy purchases from the US in response to new import tariffs. By moving further down in the value chain, Brazil would add value to exports and be less exposed to commodities price fluctuations and geopolitical shifts.
