Biodiesel Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Biodiesel Market Trends and Insights

Renewable-fuel Blend Mandates Expanding

National blend programmes are scaling rapidly, guaranteeing sizeable offtake volumes and underpinning long-term financing across the biodiesel market. Brazil’s Fuel-of-the-Future law raises the obligatory blend from B14 to B17 by 2027 and foresees B25 later in the decade, lifting domestic biodiesel use from 9.3 billion litres in 2024 to 12.3 billion litres by 2027.^{[1]D. Holt, “Brazil Fuel of the Future Law Boosts Biodiesel Blend,” agweb.com} Indonesia is rolling out its B40 programme, while all EU member states must align with higher advanced biofuel quotas under RED-III. British Columbia now insists that 8% of diesel renewable content be produced domestically from April 2025, signalling how mandates increasingly favour local supply. Renewable Fuel Standard obligations remain in force in the United States and provide a dependable compliance baseline. These rules establish price floors, enabling producers to expand capacity and adopt efficiency-enhancing technologies.

Hard-to-Abate Sectors Seeking Drop-in Decarbonisation

Mining, marine, and rail operators' segments, where electrification lags, are adopting biodiesel blends to meet near-term carbon-reduction goals without infrastructure overhauls. Global mining firms spend roughly USD 7 billion annually on diesel equipment; switching to B20 or renewable diesel delivers 50–85% lifecycle emission cuts while lowering particulate outputs sharply.^{[2]Engine Technology Forum, “Biodiesel Reduces Mining Emissions,” engine-technology.org} In Europe, Chevron Renewable Energy Group supplies EN 14214-grade fuel that cuts particulate matter in mines from 300-800 µg m³ to 50-200 µg m³. Marine uptake is growing through REG–Bunker Holding alliances to deploy B30, and freight rail trials show seamless engine compatibility. Willingness to pay decarbonisation premiums in these sectors supports higher-margin sales within the biodiesel market.

HVO and SAF Capacity Build-outs

Oil majors are investing heavily in HVO assets to harvest co-product value and create SAF supply chains, a trend reshaping competitive dynamics in the biodiesel industry. Neste lifted renewable aviation-fuel capacity to 1.5 million t pa in April 2025 and is enlarging its Rotterdam complex into the world’s largest renewable diesel and SAF facility by 2027.^{[3]Neste, “Annual Report 2025 – Renewable Products,” neste.com} OMV’s EUR 200 million co-processing line at Schwechat converts 160,000 t of liquid biomass yearly, avoiding 360,000 t of fossil CO₂.^{[4]Euro-Petrole, “OMV Starts Schwechat Co-Processing Unit,” euro-petrole.com} BP took full control of BP Bunge Bioenergia, yet shelved two greenfield SAF projects for portfolio optimisation. Premium-grade glycerin from HVO outputs further improves plant economics, reinforcing capital flows toward this pathway.

Waste- & Residue-based Feedstock Credits

Used cooking oil, tallow, and similar residues collect superior carbon credits under the Low Carbon Fuel Standards, widening the spread between biodiesel and fossil diesel margins. Imports of UCO into California rose markedly in 2024 as producers chased lower carbon-intensity scores, while waste inputs formed 88% of Neste’s renewable feedstock slate in Q2 2024. Brazil’s beef tallow exports jumped to 198,340 t in the first 11 months of 2023, doubling year-on-year, as overseas demand for low-CI feedstock increased. These incentives accelerate the biodiesel market pivot from edible oils toward circular-economy streams.

Feedstock Price Volatility

Soybean-oil quotations oscillated sharply through 2024 as Brazil’s higher blends drew more volumes, eroding producer margins and prompting output optimisation at several plants. UCO values approached virgin-oil parity once LCFS credits were incorporated, diluting expected cost advantages. Neste cited elevated feedstock costs as a principal factor behind depressed margins in 2024 despite flat diesel benchmarks. Climatic disruptions and ongoing food-versus-fuel tensions compound price uncertainty, compelling firms across the biodiesel market to diversify inputs or adopt hedging strategies where possible.

Land-use Change Scrutiny

EU RED-II caps traditional crop-based biofuels at 7% of transport energy and imposes strict land-use-change documentation, effectively narrowing the eligible pool of palm- and soy-derived esters for European customers. Compliance demands cradle-to-gate traceability, adding certification expense and limiting feedstock flexibility for exporters. Producers unable to verify low-ILUC status may face market exclusion, underscoring why waste-derived alternatives are gathering momentum inside the biodiesel market.

Segment Analysis

By Feedstock: Waste Streams Gathering Speed

Vegetable oils still delivered 63.45% of the 2025 supply, sustaining baseline volumes for the biodiesel market, yet their growth tempo is flattening as policymakers and buyers chase lower carbon-intensity scores. Palm oil dominates South-East Asia, whereas soybean oil prevails in the Americas, but each faces scrutiny over land-use risks.

Waste cooking oil and tallow are projected to expand at a 10.15% CAGR, well ahead of edible oils, thanks to premium LCFS credits and emerging advanced-biofuel quotas. Brazil’s beef-tallow exports, rising 144% year-on-year, signal widening global arbitrage. Algae-based oils and winter-canola pilots from the Neste–Bayer alliance illustrate the exploratory edge of feedstock R&D. Competition for residues is now sharpening, inserting new price volatility while steadily raising the sustainability bar across the biodiesel market.

By Production Process: HVO Ascendant

The familiar trans-esterification route retained 70.35% share of the biodiesel market size in 2025 by virtue of its comparatively light capital burden and well-established supply chain compatibility. It remains the mainstay for many small-to-mid producers, particularly in developing economies with limited refinery integration.

However, HVO capacity is forecast to clock a 11.74% CAGR as oil majors leverage existing hydrotreaters to create fungible diesel, SAF, and naphtha streams. The biodiesel market benefits because HVO commands infrastructure parity with fossil diesel, enabling B100 equivalents without cold-flow problems. Higher-value technical-grade glycerin and flexible feedstock windows further enhance plant returns, spurring a pipeline of conversions and greenfields across Europe, North America, and Asia-Pacific.

By Blend Level: High-Concentration Uptake Rising

B5-and-below products represented 47.58% of 2025 volumes, serving the mainstream automotive fleet with minimal infrastructure change. These blends underpin mass-market stability within the biodiesel market because almost all diesel vehicles can use them under manufacturer warranties.

Mandated jumps to B20 in markets such as Indonesia and niche B100 rollouts for mining and marine customers are pivoting growth toward higher blends. Pure biodiesel is set to climb at 10.82% CAGR through 2031. Operators adopting B30–B100 report lifecycle CO₂ reductions exceeding 80% and substantial particulate abatement, important metrics for ESG-oriented cargo owners and public procurement agencies.

By Application: Industrial Diversification Broadens Demand

Road transportation still commanded 68.25% of 2025 consumption, anchored by haulage and municipal fleet compliance rules. Electrification headwinds remain subdued in heavy freight, leaving a substantial diesel pool open for substitution.

Industrial, marine, rail, and power segments are forecast to increase at a 12.58% CAGR, signifying meaningful diversification of the biodiesel market. For instance, marine bunker suppliers in the Netherlands are now bunkering river-cruise fleets with B30 derived from waste oils. Remote mines are trialling B100 in gensets to reduce Scope 1 emissions without investing in grid upgrades. Such cross-sector adoption embeds biodiesel as a flexible decarbonisation lever beyond highway use.

Geography Analysis

Europe delivered 37.62% of global sales in 2025 and continues to reward low-carbon biodiesel through RED-III quotas, national carbon taxes, and subsidy schemes for waste-based feedstocks. Germany, France, and the United Kingdom each tightened blend obligations in 2025, and the Nordics are frontrunners in collecting municipal UCO for local processing, reinforcing regional circular-economy objectives. Sustainability certification remains stringent however, limiting feedstock choice and raising administrative overhead.

Asia-Pacific offers the fastest expansion path, showing a 10.02% CAGR projection to 2031 as Indonesia escalates toward B40, India allocates grants for capacity, and China integrates biodiesel into its dual-carbon roadmap. Accessible palm-oil supply, rising urban diesel demand, and supportive fiscal incentives make the region a strategic growth engine inside the biodiesel market. Nonetheless, export potential to Europe is checked by deforestation-linked rulings, compelling producers to upgrade traceability protocols.

North America holds mature infrastructure and policy stability via the U.S. Renewable Fuel Standard and an expanding patchwork of state-level Low Carbon Fuel Standards. Advanced credit trading deepens revenue pools, yet LCFS credit oversupply recently squeezed pricing. South America, led by Brazil’s trajectory toward B25, is simultaneously a feedstock powerhouse and a major internal market. Argentina’s producers navigate export tariffs but maintain competitiveness regionally through soybean-oil scale and established esterification expertise.

Regulatory Landscape

Biodiesel demand and pricing are shaped by blending and credit regimes that define compliance volumes and reward lower-carbon feedstocks. In the United States, the Environmental Protection Agency finalized Renewable Fuel Standard (RFS) standards for 2026 and 2027 in April 2026, including biomass-based diesel requirements expressed in RINs (9.07 billion RINs for 2026). This reinforced the importance of D4 RIN value in producer economics and offtake contracting.

In Europe, RED III implementation tightens sustainability requirements and crop-based limits, with the European Biodiesel Board tracking a 2026 crop cap for diesel. That direction supports a shift toward waste and residue pathways to preserve eligibility and avoid tighter land-use scrutiny. Outside the US and EU, fuel-quality and local-content rules influence market access and product specifications. Australia issued the Fuel Quality Standards (Biodiesel) Determination 2025, creating an updated compliance reference point for biodiesel supplied to the domestic market. At the provincial level in Canada, British Columbia implemented an April 2025 requirement that 8% of diesel renewable content be produced domestically, which can redirect trade flows and favor localized production and feedstock sourcing.

Market Opportunities and Future Outlook

Near-term whitespace centers on aligning capacity utilization and expansion with policy volumes, while upgrading supply chains for low-carbon, credit-advantaged molecules. The April 2026 US EPA final RFS standards for 2026 and 2027 increased compliance certainty for biomass-based diesel through defined RIN-based requirements. That supports multi-year offtake and credit-optimization structures for producers selling into D4 RIN and state LCFS markets.

In April 2026, Eslinger Biofuels announced a five-year arrangement with STX Group spanning D4 RINs, California LCFS credits, and 45Z Clean Fuel Production Credits. The deal points to a shift from more spot exposure toward structured monetization models that can underpin plant debottlenecking and feedstock flexibility investments. Opportunities also concentrate in integrated, feedstock-secure builds and in mandates that increase the share of higher blends within mainstream diesel pools. In Brazil, Potencial Group inaugurated a soy crusher and refined glycerin plant in Lapa in March 2026 to expand biodiesel output capacity, reflecting continued vertical integration from crushing through coproduct upgrading. In Asia-Pacific, Indonesia launched a B50 biodiesel mandate effective July 1, 2026, expanding the addressable pool for palm-based diesel and raising the importance of traceability, logistics, and cold-flow management for higher-blend distribution. In Europe, RED III implementation and tighter crop-based limits create a commercial opening for waste cooking oil, tallow, and other residues, although the resulting competition for these inputs strengthens the case for collection networks, pretreatment capability, and certification-ready documentation across the supply base.
