Ministério de Minas e Energia - The ministry confirmed that, starting in May, Brazil will begin technical tests to raise the biodiesel blend in diesel — a move that could shift fuel supply dynamics and policy decisions scheduled for 2026.
- In short: Tests beginning in May aim to enable a move to B16 (16% biodiesel), with regulators and industry preparing technical and financial participation.
Why the May tests matter
The announcement in São Paulo by Marlon Arraes, secretário substituto de Petróleo, Gás Natural e Biocombustíveis, marks the start of a technical phase to evaluate engine compatibility and fuel behavior at higher biodiesel concentrations. These tests are designed to underpin regulatory choices later in 2026. IEA biofuels analysis highlights that scaled biofuel use is among available levers to improve transport resilience and cut emissions.
Industry group APROBIO has signalled expectations that Brazil could adopt B16 this year and has offered support, including participation in financing test stages.
"the tests are fundamental to guarantee technical safety before any expansion of the blend, both in the domestic market and in possible regional applications."
Context and wider impact
Moving to B16 would be a step toward the gradual targets outlined in the Lei do Combustível do Futuro, which contemplates increases up to 20% over time. The change could reinforce domestic biodiesel production, reduce fossil diesel imports and add predictability for agricultural and industrial chains tied to vegetable oil supply.
Beyond immediate supply effects, higher biodiesel blends can have implications for maintenance schedules, warranty considerations and fuel logistics — reasons why the May tests focus on engines and fuel handling before any nationwide mandate.
