Brazil Opens Public Consultation on CBIO Targets Through 2036

Why it matters: CBIOs are the compliance backbone of RenovaBio, Brazil’s national biofuel policy. Setting a ten-year trajectory for the first time gives fuel distributors, biofuel producers and financial intermediaries a long-term price signal, but the final numbers are not locked in. The consultation stage means every stakeholder, from ethanol mills to petroleum distributors, now has a window to push the targets higher or lower before they become binding regulation.

What changes for fuel distributors in practice

Under RenovaBio, every distributor that sells fossil-derived liquid fuels in Brazil receives an individual CBIO obligation each year. That individual target is calculated by the National Agency of Petroleum, Natural Gas and Biofuels (ANP) based on the distributor’s share of total fossil fuel sales. When the MME raises the aggregate national target, each distributor’s slice grows proportionally. A trajectory that climbs to 73.45 million CBIOs in 2036 means distributors will need to either purchase more credits on the B3 exchange or face penalties for non-compliance.

The cost impact depends on CBIO spot prices at the time of purchase. Distributors that hedge early or sign long-term offtake agreements with certified biofuel producers can lock in lower costs, while those that wait until the compliance deadline risk buying at peak prices. For smaller regional distributors with thinner margins, the rising trajectory increases the financial pressure to plan CBIO procurement years in advance rather than quarter by quarter.

What is still open and what needs to happen next

A public consultation is not a final rule. After the comment period closes, the MME will review submissions, may revise the annual figures, and then publish a definitive resolution. Several elements remain unresolved. The proposed targets assume certain projections for fossil fuel demand and biofuel supply growth over the decade, but those projections could shift if Brazil’s vehicle fleet electrifies faster than expected or if new biofuel capacity (particularly biomethane and sustainable aviation fuel) comes online at a different pace. If actual fossil fuel consumption falls below the projections embedded in the targets, the annual CBIO requirement could overshoot what the market can absorb, pushing credit prices down. Conversely, if consumption stays high and biofuel capacity lags, CBIO prices could spike.

The consultation also does not detail how the MME will handle mid-course corrections. Previous single-year or short-horizon targets allowed annual recalibration. A ten-year schedule offers predictability but reduces flexibility. Stakeholders are likely to debate whether the resolution should include a review clause, for instance a mandatory reassessment every three years, to adjust targets if underlying assumptions prove wrong.

Who gains and who faces pressure

Certified biofuel producers, primarily sugarcane ethanol mills and biodiesel plants, stand to benefit. Higher aggregate CBIO demand supports credit prices and gives producers a revenue stream on top of fuel sales. Mills that have already invested in energy efficiency and emissions certification under RenovaBio are positioned to issue more credits per liter of biofuel produced, capturing a larger share of that demand.

On the other side, large petroleum distributors, including BR Distribuidora (now Vibra Energia), Raizen and Ipiranga, will carry the bulk of the compliance cost. While these companies also have biofuel operations or offtake contracts that partially offset their obligations, a rising ten-year trajectory locks in growing expenditure. Distributors that rely more heavily on imported fossil fuels and have less integration with domestic biofuel supply chains face the steepest cost curve. The consultation period is their opportunity to argue for a flatter trajectory or built-in adjustment mechanisms.
