IEA sees biofuel use doubling by 2030, still barely denting oil demand
The IEA forecasts global biofuel consumption will more than double by 2030, yet the projected volumes still amount to roughly 6% of current oil supply.
Global biofuel use is set to more than double by 2030 under IEA forecasts, but the projected volumes would still replace only a sliver of the world's oil supply. The agency's outlook sees biofuels reaching the equivalent of around 6% of current global crude output, a figure that underscores how slowly the transport fuel transition is moving despite aggressive policy support.3
The numbers matter for refiners and fuel suppliers planning capital spending. Doubling biofuels still means oil retains the overwhelming share of the transport fuel pool, which does little to ease the long-term demand uncertainty that has kept ICE Brent crude front-month at $95.91/bbl as of September 4 after a sustained rally through the summer.2
Traders have been here before with the IEA's scenario work. In the "Net Zero by 2050" report published in 2021, the agency projected oil demand would drop by more than a quarter by 2030. That scenario rested on radical policy action that has not arrived at the pace required, leaving current forecasts far more conservative on oil's decline path. Where the 2021 roadmap saw a rapid fall, the latest work takes a slower curve.2
The more realistic framing still creates real investment signals. IATA data from last year showed sustainable aviation fuel production at just 0.6% of total jet fuel consumption, miles away from the 65% share the aviation industry has targeted for 2050 to reach net zero. With SAF currently costing two to three times conventional jet fuel, airlines have little incentive to lift uptake ahead of mandates.6
Policy timetables in Asia show how uneven the ramp-up will be. Japan currently mandates oil companies to supply 500,000 kilolitres per year of bioethanol for transport through fiscal 2027, with ANRE reviewing volumes along with lifecycle emissions and overseas supply chains. Brazil and Thailand stand out as key supply candidates for the Japanese market, a sign that feedstock availability rather than demand is shaping where production scales.5
The gap between biofuel aspirations and biofuel reality fits a broader pattern in the IEA's analysis. Solar generation is expected to jump around 30% this year and wind by roughly 10%, yet both start from a much further behind position than the fossil generation they aim to displace. Clean energy additions are rising faster than ever, but coal remains the undisputed king of global power generation.7
Electricity's share of global energy use is projected to climb from about 23% now to over 50% by 2050, a structural shift that will eventually erode oil's dominance in transport as electrification advances. But that timeline stretches beyond most corporate planning horizons and beyond the current investment cycle where upstream spending still dwarfs biofuel capacity.3
Fossil fuels, the IEA acknowledges, still power much of the world. Every geopolitical crisis from Middle East wars to Strait of Hormuz disruptions has reinforced the assumption that when energy security matters, oil and gas deliver. That assumption is not dying quickly, which is why the agency's biofuel forecast doubling still leaves oil demand largely intact by 2030.4
Policy, not technology, is what would change the math. The IEA's WEO 2025, released on Wednesday (2026-05-20), called for greater diversification of energy supplies and stronger international cooperation. Critical mineral supply chains face their own concentration risk, with one country dominating refining for 19 of 20 key strategic minerals at an average 70% global market share.1
Spending patterns reflect the new priorities. Global data centre investment is estimated to reach $580 billion in 2025, surpassing the $540 billion being spent on oil supply. Electricity generation investments have surged nearly 70% since 2015, though grid spending has increased at less than half that rate, creating bottlenecks that could slow electrification's advance.1
For traders tracking carbon exposure, the pace of biofuel mandate tightening in Europe and Asia matters most, since deeper blending into road transport would reduce EUA demand from refiners. ICE EUA Dec-rolling prices will track that policy direction. Diesel and jet fuel demand in both regions remains sticky enough that any acceleration of biofuel obligations would move physical supply balances before it shifts headline crude volumes.1
For now, the biofuel doubling is a rounding error in the global oil balance. The next signal comes when the IEA updates its 2030 demand outlook, showing whether the agency still believes oil consumption peaks before the decade closes or whether producers extend their run into a market where ICE Brent crude front-month holds above $95/bbl.2
