COP30 opened with bold pledges. At the leaders’ summit on Nov. 6 and 7, countries agreed to quadruple sustainable fuel use, expand Brazil’s carbon market coalition, and channel USD 5.5 billion toward rainforest protection. The real test, however, will be turning these promises into action.
Expand sustainable fuels at least 4 times by 2035
Endorsed by 19 countries including Japan and India, the “Belém Commitment for Sustainable Fuels,” or “Belém 4x,”aims to quadruple the use of sustainable fuels by 2035 compared with 2024 levels. Leaders said the initiative will provide high-level political backing for scaling up the global production and use of sustainable fuels.
While several existing international initiatives promote sustainable fuels, the Belém 4x seeks to serve as a unified political platform to accelerate collective action and industry growth worldwide, helping the aviation, shipping, road transport, and industrial sectors reduce carbon emissions.
