COP31 has exposed a striking gap between global climate ambition and energy policy reality. A new International Energy Agency report suggests that sustainable fuels are gaining momentum — but nowhere near fast enough to meet the world’s ambitions. For biomass, the findings reveal both a political contradiction and a major economic opportunity.
A Climate Promise Meets an Uncomfortable Reality
The global energy transition has no shortage of ambitious targets. Governments have committed to expanding renewable energy, improving energy efficiency and reducing dependence on fossil fuels. Yet one of the most consequential promises has received surprisingly little public attention: the ambition to quadruple global sustainable fuel consumption by 2035. Launched in October 2025 by Brazil, India, Italy and Japan, the Belém 4X Pledge on Sustainable Fuels was designed to accelerate the deployment of liquid biofuels, biogases, low-emissions hydrogen and hydrogen-derived fuels. By September 2026, 32 countries had endorsed the initiative, representing a substantial share of global sustainable fuel demand.
The political message was clear. Electrification alone would not be sufficient to decarbonise the global economy. Aviation, shipping, industrial production and parts of road transport would continue to require fuels, even as renewable electricity expanded. One year later, the International Energy Agency has delivered an uncomfortable assessment.
In its new COP30 Belém Sustainable Fuels Pledge tracking report, published on 10 November 2026 and presented at COP31 in Antalya, Türkiye, the IEA projects that global demand for sustainable fuels will increase by approximately one-third between 2024 and 2030 under current policies and market conditions.
That is meaningful growth. But it falls substantially short of the trajectory required to meet the 2035 ambition. According to the IEA, projected sustainable fuel demand in 2030 is around 30% below the level needed to remain on track.
The contradiction is striking: governments have endorsed a major expansion of sustainable fuels, yet existing policy frameworks are not delivering the necessary acceleration.
The world has recognised the importance of sustainable fuels. It has not yet created the market conditions required to deploy them at the promised scale.
For the biomass industry, this distinction is fundamental.
The Numbers Reveal More Than a Policy Gap
The IEA’s findings deserve attention beyond the headline.
Global sustainable liquid and gaseous fuel demand approximately doubled between 2010 and 2024, reaching almost seven exajoules. Despite that expansion, sustainable fuels still accounted for only around 1.3% of global final energy consumption in 2024. This is an important reminder of how early the transition remains outside the electricity sector. Renewable electricity has experienced extraordinary technological and commercial progress. Solar photovoltaics, wind turbines and battery storage have attracted enormous investment and increasingly benefit from established supply chains.
Sustainable fuels face a different set of challenges. They must compete with fossil fuels that benefit from extensive existing infrastructure, established international trading systems and deeply integrated industrial processes. Their production often involves more complicated feedstock logistics, higher capital costs and regulatory uncertainty.
Nevertheless, the IEA’s earlier Delivering Sustainable Fuels: Pathways to 2035 report demonstrated that a much faster expansion is technically and politically conceivable. Full implementation of existing and proposed national and international policies, combined with additional measures to overcome deployment barriers, could put sustainable fuel use on a pathway towards quadrupling by 2035.
The latest tracking report does not invalidate that potential. It reveals the difference between an accelerated policy pathway and the market trajectory expected under current conditions.
This is precisely where the debate should shift. The question is no longer whether sustainable fuels can contribute to the energy transition. It is whether governments are prepared to establish the investment conditions necessary for them to do so.
The Surprising Winner: Biomass Is Already Driving the Transition
Perhaps the most interesting finding in the IEA report concerns the technologies actually delivering growth. While hydrogen and synthetic fuels frequently dominate discussions about the future of sustainable energy, the near-term expansion is being driven overwhelmingly by bioenergy. The IEA estimates that liquid biofuels will account for nearly 70% of projected global sustainable fuel growth through 2030, with road transport providing much of the demand.
This is a remarkable finding. In political debates, biomass is sometimes portrayed as a transitional technology whose importance will decline as more advanced solutions emerge. Yet the IEA’s latest analysis suggests that established biofuel technologies are doing much of the practical work of reducing fossil-fuel dependence today.
Bioethanol, biodiesel and renewable diesel benefit from commercial production experience, existing distribution infrastructure and established regulatory frameworks. In many markets, they can be blended with conventional fuels, allowing emissions reductions without requiring the immediate replacement of entire vehicle fleets.
Biomethane offers similar advantages in gaseous energy markets. Where technically compatible and supported by appropriate regulation, it can use existing natural gas infrastructure, providing a renewable alternative for applications that remain dependent on gaseous fuels.
This does not mean hydrogen and synthetic fuels are unimportant. The IEA expects production of low-emissions hydrogen and hydrogen-based fuels from operating or investment-committed projects to rise to nearly six times its 2024 level by 2030. But rapid percentage growth from a small starting point is different from delivering large volumes of energy. The emerging reality is that biomass-derived fuels are not merely waiting for the next generation of technologies.
They are already providing much of the sustainable-fuel growth on which the global transition depends.
Energy Security Is Changing the Political Equation
Climate policy is no longer the only reason governments are expanding biofuels. Energy security has become an increasingly important driver. The IEA reports that sustainable fuels are already reducing dependence on imported fossil fuels in road transport by up to 40% in certain markets. This is particularly significant for countries that depend heavily on imported oil and gas but possess substantial agricultural, forestry or organic waste resources. In 2026, several countries in Southeast Asia and Latin America increased biofuel blending requirements in response to higher fossil-fuel prices and supply pressures associated with the conflict in the Middle East.
The implications extend beyond emissions. Domestic biofuel production can reduce exposure to international oil markets, support agricultural value chains, generate rural employment and diversify national energy supplies. Brazil illustrates the strategic importance of this approach. Its long-established ethanol industry demonstrates how biofuels can become part of national energy infrastructure rather than remaining a marginal environmental initiative. India’s ethanol blending programme similarly illustrates how policy-driven demand can accelerate market development, although feedstock sustainability, water use and competing agricultural demands remain important considerations.
For many emerging economies, sustainable biomass offers something particularly valuable: an opportunity to connect energy transition policy with domestic economic development.
Solar panels and wind turbines produce renewable electricity. Biomass can additionally create markets for agricultural products, forestry by-products, organic residues and waste-management services. The economic benefits are not automatic, and poorly designed policies can create undesirable land-use incentives. Nevertheless, the potential to combine energy security, rural development and emissions reductions helps explain why biofuels are receiving renewed political attention.
Why Electrification Alone Cannot Deliver Net Zero
The broader significance of the Belém Pledge lies in a fundamental limitation of the energy transition. Electricity is an exceptionally efficient energy carrier for many applications. Electric vehicles, heat pumps and renewable power generation are essential components of decarbonisation. But not every sector can be electrified easily, economically or rapidly. Long-distance aviation requires energy-dense fuels. International shipping operates vessels with long service lives and demanding fuel-storage requirements. Industrial facilities often require high-temperature heat or carbon-containing feedstocks. Large existing fleets of combustion-engine vehicles will remain in use for years.
In these applications, sustainable fuels can complement electrification rather than compete with it. This is particularly important for policymakers who view decarbonisation primarily through the lens of electricity generation. Replacing fossil electricity is necessary, but it does not automatically eliminate fossil-fuel demand across the wider economy. Oil and gas are not used exclusively to generate electricity. They are also used as transport fuels, industrial inputs and chemical feedstocks. Consequently, a credible net-zero strategy must address both renewable electricity and sustainable molecules. Biomass occupies a distinctive position in this transition because it can provide renewable carbon as well as energy. Advanced biofuels can substitute for fossil-derived liquid fuels. Biomethane can replace fossil natural gas in suitable applications. Biomass-derived intermediates can supply chemical and industrial processes that require carbon-containing materials.
These characteristics explain why bioenergy remains relevant even in scenarios featuring extensive electrification. The future energy system will not be built around one universal technology. It will require different solutions for different applications.
The Real Bottleneck Is Investment Confidence
If sustainable fuels are strategically important, why is deployment progressing too slowly?
The answer is not simply technological immaturity. Many biofuel technologies are commercially established. Their limitations increasingly involve economics, policy design and investment risk. Producing sustainable fuels often remains more expensive than using conventional fossil fuels. Investors therefore need confidence that future demand will justify the capital expenditure required for new facilities, logistics networks and feedstock supply chains. Short-term subsidies and frequently changing blending mandates may encourage incremental production but are less effective at supporting long-lived infrastructure investments. A biofuel refinery, biomethane plant or advanced biomass conversion facility cannot be financed solely on the basis of political enthusiasm.
It requires predictable revenue. This is why the IEA emphasises clear roadmaps, reliable demand signals, robust carbon accounting, technological innovation, infrastructure development and improved access to finance. The challenge is especially acute for advanced biofuels. Conventional biofuel production benefits from established technologies and feedstock markets. Newer pathways based on lignocellulosic residues, complex waste streams or advanced conversion processes can offer additional sustainability advantages but may involve greater technical and financial risk.
Without stable policy frameworks, investors may prefer conventional energy projects or postpone decisions altogether. The result is a familiar problem in energy policy: governments announce ambitious long-term targets while leaving companies uncertain about the commercial conditions under which those targets are supposed to be achieved. For sustainable fuels, that gap is becoming increasingly difficult to ignore.
The Sustainability Paradox: Stronger Rules Could Unlock Faster Growth
A major expansion of biomass-derived fuels inevitably raises questions about feedstock availability, land use, biodiversity and greenhouse-gas accounting.
These concerns cannot be dismissed. Not every biomass resource is equally sustainable. Not every biofuel delivers the same lifecycle emissions savings. Expanding production without considering land-use change, agricultural competition or forest management could undermine the environmental objectives that justify policy support. But the conclusion should not be that biomass deployment must remain limited. Rather, the challenge is to distinguish sustainable supply chains from problematic ones and create incentives for continuous improvement. Agricultural residues, forestry by-products, organic wastes and other suitable feedstocks can contribute to sustainable fuel production, provided their extraction and use respect environmental limits and competing applications. Credible certification, lifecycle greenhouse-gas accounting and transparent sourcing can help establish that distinction. The European Union’s Renewable Energy Directive provides one example of an increasingly detailed regulatory approach to bioenergy sustainability. Other markets are developing their own requirements, although differences in accounting methods and certification standards can complicate international trade.
This creates a paradox. Stricter sustainability requirements may initially increase compliance costs and constrain certain feedstock sources. Yet credible and internationally compatible standards can also reduce regulatory uncertainty, improve public acceptance and make long-term investment more attractive. For the biomass sector, sustainability governance should therefore be understood not merely as a regulatory burden, but as a potential foundation for future market expansion. The objective should be to increase sustainable fuel production without weakening environmental safeguards. That requires better technology, better feedstock management and better regulation — not the abandonment of bioenergy.
A Market Opportunity Hidden Behind the Political Failure
The IEA’s findings also reveal a significant economic opportunity. Its Energy Technology Perspectives 2026 report projects that the global market value of low-emissions fuels could increase from approximately USD 215 billion in 2025 to USD 390 billion by 2035 under its Current Policies Scenario. Around 60% of the projected market growth is expected to come from relatively mature biofuel technologies, including biomethane, bioethanol and biodiesel. These figures suggest that sustainable fuels could become a major industrial market even without full achievement of the Belém Pledge.
Stronger policy implementation would potentially create additional demand. For biomass producers, fuel manufacturers, technology providers and infrastructure investors, the implications are substantial. The industry could benefit from expanding demand for certified feedstocks, improved biomass logistics, advanced conversion technologies and integrated production systems. Countries with established agricultural and forestry sectors may also gain opportunities to develop domestic processing capacity rather than exporting only raw materials.
However, market growth will not be distributed equally. Companies able to demonstrate reliable feedstock sourcing, competitive production costs and credible greenhouse-gas performance are likely to be better positioned than those dependent on uncertain subsidies or controversial raw materials. The next phase of the biomass industry may therefore be characterised by increasing differentiation between operators. Sustainability performance, technological efficiency and access to long-term demand could become decisive competitive advantages.
COP31: From Political Ambition to Market Delivery
The first anniversary of the Belém Pledge provides an opportunity to reassess the international approach to sustainable fuels. There are encouraging signs. According to the IEA, sustainable fuel demand increased by 9% over the preceding year in countries endorsing the pledge, compared with 7% elsewhere. Under current policies, demand in endorsing countries is projected to grow at a compound annual rate of nearly 7% through 2030, compared with approximately 3% in non-endorsing countries. This suggests that political commitment can be associated with faster market development, although the figures do not establish that endorsement alone caused the difference.
Nevertheless, the overall trajectory remains insufficient. The countries supporting the pledge account for almost 40% of global sustainable fuel demand. Broader international participation, stronger implementation and more effective investment frameworks will be necessary to achieve the global ambition. The policy response should therefore focus on practical delivery. Governments need to translate long-term targets into credible intermediate milestones. Fuel suppliers and industrial consumers need predictable demand frameworks. Investors need confidence that sustainability requirements and market incentives will remain sufficiently stable over the lifetime of their projects.
International cooperation will also be important. Divergent lifecycle accounting methods, inconsistent sustainability certification and incompatible fuel standards can create unnecessary barriers to trade and investment. A more coordinated approach could help sustainable fuels develop into an increasingly integrated international market while preserving environmental integrity. The Belém Pledge provides a political framework for this process. Its credibility will ultimately depend on implementation.
The Bigger Question: Is Biomass Being Undervalued?
The IEA’s latest findings challenge a persistent assumption in energy policy: that sustainable biomass is primarily a legacy renewable technology whose importance will gradually diminish. The evidence points towards a more differentiated future. Direct electrification will continue to expand and will often be the most efficient solution. But demand for sustainable liquid and gaseous fuels is also expected to grow, particularly in sectors where fossil fuels are difficult to replace.
Biomass-derived fuels are already responsible for much of that growth. Their contribution extends beyond greenhouse-gas reductions to energy security, industrial development and rural economic opportunities. This does not justify unrestricted biomass expansion. Sustainable feedstocks are finite, and competing uses must be considered. It does, however, strengthen the case for policies that recognise the specific value of biomass in applications where renewable molecules are difficult to substitute. The strategic mistake would be to judge biomass exclusively by its ability to compete with wind and solar in electricity generation. Its potentially greater long-term value lies elsewhere: in renewable fuels, renewable carbon, flexible energy supply and, where appropriate, carbon-removal technologies.
These functions will remain relevant even as the electricity system becomes increasingly renewable.
Conclusion: The World Does Not Need Another Pledge. It Needs a Sustainable Fuels Market.
The new IEA report delivers two messages.
The first is a warning. Under current policies and market conditions, sustainable fuel demand is not growing quickly enough to remain on track for the ambition of quadrupling global use by 2035.
The second is an opportunity. Sustainable fuels are already expanding, and biomass-derived technologies account for a substantial share of that progress.
The challenge is therefore not to invent an entirely new energy solution. It is to create the conditions under which existing and emerging sustainable fuel technologies can scale responsibly. That means predictable demand, credible sustainability standards, investment in infrastructure, innovation and access to finance.
For governments, the choice is increasingly clear: continue announcing ambitious targets without providing sufficient market support, or establish policies capable of turning those targets into industrial reality.
For the biomass sector, the implications are equally clear. Sustainable biomass is not a peripheral element of the energy transition. It is already contributing to the displacement of fossil fuels and could play a substantially larger role in the coming decade.
The world has promised four times more sustainable fuels. The real question is whether policymakers are prepared to build the market that makes it possible.
