The Advantages of Biofuels

Biofuels can cut lifecycle greenhouse-gas emissions, strengthen energy security, leverage existing engines and infrastructure, improve some aspects of air quality, and support rural economies—especially when produced from wastes, residues, or high-yield crops using sustainable practices. They also provide practical decarbonization options for hard-to-electrify sectors such as aviation, shipping, and long-haul trucking. Below, we explain where these advantages come from, when they are strongest, and how they are shaping fuel markets today.

What Biofuels Are and Where They Fit

Biofuels are liquid or gaseous fuels made from biological sources such as crops, agricultural residues, used cooking oil, forest waste, municipal organic waste, or animal manure. Common forms include ethanol (blended into gasoline), biodiesel and renewable diesel (substitutes for petroleum diesel), biogas/renewable natural gas (RNG), and sustainable aviation fuel (SAF). Their key role is providing lower-carbon energy where batteries or direct electrification are less practical—most notably in aviation, marine, heavy-duty road transport, and some industrial applications.

Key Advantages at a Glance

The following points summarize the main benefits most frequently cited by researchers, industry, and policymakers. The scale of each advantage depends on feedstock, farming and land-use practices, conversion technology, and the final use case.

• Lower lifecycle greenhouse-gas (GHG) emissions than fossil fuels, often by 50–80% for waste-based biodiesel/renewable diesel and many SAF pathways; even higher for some cellulosic routes, especially with carbon capture.
• Practical decarbonization of hard-to-electrify sectors (aviation, shipping, heavy-duty trucks) via drop-in or compatible fuels.
• Energy security through domestic feedstock use, diversified supply, and reduced exposure to oil price shocks.
• Air-quality gains such as lower particulate matter, sulfur, and certain toxic aromatics, with modern engines and controls.
• Valorization of wastes and residues, cutting methane from landfills and manure when converted to biogas/RNG or advanced liquid fuels.
• Compatibility with existing engines and fuel infrastructure via blends (e.g., ethanol, biodiesel) or drop-in fuels (renewable diesel, some SAF).
• Rural economic development and new revenue streams for farmers, foresters, and waste managers.
• Potential for negative emissions when paired with carbon capture and storage (BECCS) or when producing biochar as a co-product.
• Generally better biodegradability and lower toxicity than petroleum fuels, reducing environmental impact of spills.

Taken together, these advantages make biofuels a flexible tool for lowering emissions today while longer-term solutions—such as widespread electrification and green hydrogen—scale up.

Climate and Environmental Benefits

Lower lifecycle greenhouse-gas emissions

Because plants absorb CO2 while growing, biofuels can significantly reduce net emissions compared with fossil fuels when produced sustainably. Typical results (which vary by feedstock and technology) include 20–40% reductions for corn-ethanol in many U.S. pathways, 60–90% for sugarcane ethanol, around 50–80% for waste-based biodiesel and renewable diesel, and roughly 50–80% for common SAF routes like HEFA when using used cooking oil or tallow. Cellulosic fuels from agricultural residues or energy grasses can exceed 80% reductions. The strongest performance comes from waste and residue feedstocks that avoid indirect land-use change.

Negative emissions potential

When biomass conversion is combined with carbon capture and storage—known as BECCS—biofuel facilities can remove more CO2 from the atmosphere than they emit, delivering net-negative fuels. Some biogas-to-fuel pathways that eliminate methane from manure or landfill sources can also achieve net-negative lifecycle emissions.

Cleaner local air

Biofuels contain little or no sulfur and typically reduce particulate matter (PM), carbon monoxide, and certain toxic aromatics relative to petroleum fuels. Ethanol’s high oxygen content lowers carbon monoxide and benzene in gasoline blends; renewable diesel often lowers PM and nitrogen oxides (NOx) compared with petroleum diesel in many modern engines; and biodiesel blends generally cut PM and hydrocarbons (NOx effects can vary by engine and blend). Real-world outcomes depend on engine technology and emission controls.

Waste reduction and circularity

Converting used cooking oil, animal fats, forestry residues, agricultural byproducts, or municipal organic waste into fuel creates value from materials that might otherwise decompose and emit methane. Biogas and RNG systems, in particular, capture methane—an especially potent greenhouse gas—before it escapes, turning a liability into a low-carbon energy asset.

Energy System and Security Advantages

Beyond emissions, biofuels offer system-level benefits that help countries and companies manage risk and keep critical services running.

• Diversified supply and domestic production reduce reliance on imported oil and enhance resilience to geopolitics and price volatility.
• Drop-in compatibility: renewable diesel (HVO) and many SAF blends can be used in existing engines and fueling infrastructure with minimal changes.
• Storability and transportability provide energy reliability advantages over some intermittent renewable electricity solutions, especially for backup and remote operations.
• Fit for hard-to-electrify uses—aviation, long-haul trucking, mining, and marine—where high energy density liquid fuels are still essential.
• Seasonal and emergency readiness: liquid biofuels can be stockpiled to support disaster response and grid contingencies.

These characteristics allow biofuels to complement electrification and hydrogen, filling near- and medium-term gaps in the energy transition while infrastructure evolves.

Economic and Social Upsides

From farm to fuel pump, biofuel value chains can spur investment and broaden economic participation, especially in rural regions.

• Job creation in agriculture, logistics, processing, and engineering, with new revenue streams for farmers and foresters.
• Repurposing existing refining assets—such as converting petroleum refineries to renewable diesel—preserves industrial jobs and reduces stranded-asset risk.
• Co-products (e.g., distillers grains for animal feed, captured CO2 for industry, biochar for soil) add economic value and can improve sustainability metrics.
• Price hedging and local content benefits help stabilize fuel costs and retain more energy spending within domestic economies.

Where policies reward verified emissions cuts, low-carbon intensity biofuels can also earn credits, improving project bankability and rural tax bases.

Performance and Safety Advantages

Ethanol’s high octane improves anti-knock performance in gasoline blends; renewable diesel’s high cetane enhances ignition quality and often improves cold-start and combustion characteristics; and low-level biodiesel blends increase fuel lubricity, reducing engine wear. Many biofuels are less toxic and more biodegradable than petroleum counterparts, lowering environmental and cleanup impacts in the event of spills. Compatibility varies by fuel and blend level, but drop-in options (renewable diesel, many SAFs) integrate smoothly with existing fleets.

Policy and Market Momentum

Policy support is accelerating deployment, reinforcing the advantages above by creating stable demand and investment signals. The European Union’s ReFuelEU Aviation law phases in mandatory SAF blending from mid-decade through 2050; the United States has created tax credits for SAF and clean fuels through the second half of the 2020s; California’s Low Carbon Fuel Standard has driven widespread adoption of renewable diesel; Brazil’s RenovaBio program issues credits for verified emissions cuts; and India is rapidly scaling ethanol blending with an eye to 20% targets in the mid-2020s. These frameworks prioritize lower-carbon pathways and favor waste- and residue-based feedstocks.

Important Context

The size of the advantages depends on doing biofuels right: prioritizing waste and residue feedstocks, improving agricultural practices, avoiding deforestation and high-impact land-use change, using efficient conversion technologies, and verifying lifecycle emissions. When those conditions are met, biofuels deliver meaningful and immediate benefits in sectors where alternatives are limited.

Summary

Biofuels offer substantial, near-term advantages: significant lifecycle GHG reductions (especially from wastes and residues), practical decarbonization of aviation and other hard-to-electrify sectors, improved energy security, air-quality benefits in many applications, rural economic gains, and even net-negative pathways with carbon capture. Their impact is strongest under robust sustainability standards and modern engine controls—making them a pivotal, flexible tool in the energy transition alongside electrification and hydrogen.
