It says a CGOB certifies biomethane’s renewable origin and the volume produced and marketed, while a CBIO is tied to a fuel’s lifecycle carbon-intensity reduction. The study discussed by EPE puts Brazil’s economic biomethane supply potential above 84 million cubic metres per day; this is an estimate, not current output. It warns that certificates could lead to double claims over the same environmental attribute, and says tax and regulatory treatment can affect the instruments’ economic value. EPE also notes that some study assumptions predate more recent regulatory decisions. ## Data ### Biomethane potential estimate Economic biomethane supply estimate cited in EPE’s analysis. Methodology: The figure is a potential estimate from the earlier study discussed by EPE, not actual production; some assumptions predate current regulations. | label | value | unit | period | basis | value_qualifier | |---|---|---|---|---|---| | Estimated economic supply potential | 84000000 | m3/day | 2026-10-09 | estimate | lower-bound | Sources: · Download data: [JSON](https://newsverum.com/api/v1/articles/brazil-epe-biomethane-certificates-origin-carbon-value-2026/data/biomethane-economic-supply-potential?lang=en&format=json) · [CSV](https://newsverum.com/api/v1/articles/brazil-epe-biomethane-certificates-origin-carbon-value-2026/data/biomethane-economic-supply-potential?lang=en&format=csv) ## Sources - [Empresa de Pesquisa Energética (EPE)]() (Source checked: 2026-10-11; Published: 2026-10-09) --- Cite the canonical URL above.
