Brazil has officially launched the “Belém 4×” Commitment for Sustainable Fuels (Compromisso de Belém pelos Combustíveis Sustentáveis), a landmark international pledge to quadruple global production and use of sustainable fuels by 2035.
The initiative, which was unveiled during a pre-COP30 event that took place in Brasília on 14 October 2025, aims to accelerate the transition toward a low-carbon global energy system.
Brazil’s proposal has already gained the support of Italy, Japan and India, the first partner nations to endorse the commitment. Discussions are now underway to expand participation ahead of COP30, which will take place from 10 to 21 November 2025 in Belém, Pará (Brazil).
The Belém 4× pledge is grounded in the new IEA report “Delivering Sustainable Fuels – Pathways to 2035”, which shows that a four-fold increase in the deployment of sustainable fuels is technically achievable and economically viable under an accelerated transition scenario.
According to the IEA, global production of sustainable fuels could rise from roughly 6.8 exajoules in 2024 to 27.5 EJ by 2035. The largest growth is expected from hydrogen-based and synthetic fuels, particularly in aviation, shipping, and heavy industry.
For Brazil and its partners, Belém 4× represents a coordinated effort to mobilize political will, international cooperation, private investment and harmonized regulation to make sustainable fuels a core pillar of global decarbonization.
The Biofuture Platform and its associated entity Biofuture Industry Council supported and reviewed the aforementioned IEA report, assisted the member countries that have joined the pledge, and contributed to relevant discussions on sustainable fuels at key recent events, including the 16th Clean Energy Ministerial Meeting (Busan, South Korea, 25-27 August 2025), the Expo 2025 (Osaka, Japan), the Climate Week (New York, USA, 21-28 September 2025) and the pre-COP30 meeting (Brasília, Brazil, 14 October 2025).
