Corte will investigate whether Renovabio’s current structure complies with gasic gas emissions reduction targets
The (Federal Court of Audit) authorized on Wednesday (16.ab.2025) the opening of an inspection to evaluate the effectiveness of the market of (decarbonization credits), provided for in (National Biofuels Policy). The goal is to verify that the current program structure is being effective to achieve greenhouse gas emissions reduction goals. This is the judgment (PDF – 352 kb).
According to data presented by the technical area, about 15 million CBIOS were negotiated by 2020, totaling approximately R $ 650 million and reaching 98% of the established goal. In 2024, more than 42 million CBIOS were generated, exceeding the goal of 39 million and moving about $ 3 billion.
The initiative came from the Audpetroleum Unit (Specialized Audit in Petroleum, Natural Gas and Mining) and was reported by the minister. The analysis will be conducted with the support of Secexenergia (Secretariat of External Energy Control and Communications).
Renovabio began to operate fully in December 2019. Since then, the market market has grown significantly. In 2020, about 15 million units were negotiated, with an approximate value of R $ 650 million. By 2024, the goal of 39 million CBIOS was exceeded, with the generation of over 42 million credits and a financial volume close to R $ 3 billion.
Each CBio corresponds to the reduction of a ton of CO₂, and fossil fuel distributors are required to buy these securities according to goals set by (National Agency of Petroleum, Natural Gas and Biofuels). The model, however, has been the target of criticism for possible market distortions, lack of predictability in the goals and concentration of the broadcasters.
According to the rapporteur, the TCU had already pointed out risks to Renovabio in a previous inspection performed in 2022, such as the insufficient generation of CBios and the inadequate inspection of the ballast of these credits. In addition, a complaint analyzed in 2024 indicated the need to evaluate the transparency and effectiveness of the rules of public policy, even without identifying formal illegalities.
For the Court, the new supervision may contribute to regulatory improvement, reduce risk of speculation and improper accumulation of credits, and mitigate negative impacts on consumers, such as increasing fuel prices.
