Brazil’s Eight-Year Campaign for Green Jet Fuel Hits the Trump Wall

Brazil's eight-year effort to establish itself as a significant supplier of green jet fuel, primarily through its ethanol makers, is being undermined by recent US policy shifts. The Trump administration's decisions to limit tax credits and impose 50% tariffs are effectively blocking Brazilian access to the critical US aviation market, negating years of lobbying and potentially impacting the global green fuels supply chain.

Analysis

A significant shift in US trade policy is poised to derail Brazil's eight-year strategic effort to become a key supplier of sustainable aviation fuel (SAF). The implementation of a 50% tariff on Brazilian green jet fuel, coupled with limitations on a critical tax credit, effectively erects prohibitive barriers to the US market, which is the world's largest for aviation. This policy reversal nullifies years of lobbying by Brazilian ethanol producers, representing a substantial setback for the industry and introducing considerable uncertainty into the global SAF supply chain. The move highlights the acute vulnerability of the renewable energy transition to geopolitical and protectionist risks, where domestic policy can abruptly alter the competitive landscape for international commodity producers.

Key Decisions for Investors

• Investors with exposure to the Brazilian ethanol sector should immediately reassess risk, as the potential loss of access to the US market via a 50% tariff represents a material threat to future revenue streams.
• Consider the divergent outlook for renewable fuel producers; US-based SAF manufacturers stand to benefit from these protectionist measures, suggesting a potential pair trade or a strategic overweighting of domestic players versus their Brazilian counterparts.
• Closely monitor US trade policy and political developments, as they have become the primary catalyst and risk factor for investments in the transatlantic green fuel supply chain.
• Evaluate the second-order effects on the aviation industry, as the exclusion of a major potential SAF supplier like Brazil could lead to supply constraints and increased price volatility for green fuels.
