The U.S. is doubling down on biofuels! The EPA’s new proposal ramps up blending mandates to 24.02 billion gallons in 2026 and 24.46 billion in 2027, a big jump from 2025’s 22.33 billion. Driven by a surge in biomass-based diesel, the plan aims to supercharge farmers and cut reliance on foreign oil. But with oil refiners crying foul and small refineries begging for exemptions, will this green push spark rural prosperity or just inflate fuel costs?

What’s the Deal?

The EPA’s Renewable Fuel Standard proposal hikes biofuel blending for oil refiners, targeting 24.02 billion gallons in 2026 and 24.46 billion in 2027, up from 22.33 billion in 2025. Biomass-based diesel steals the show, with 7.12 billion RINs (credits) for 2026, equating to 5.61 billion gallons, and 7.50 billion RINs for 2027. This dwarfs 2025’s 3.35 billion gallons, which farmers called too low. To curb imports, the EPA cut RINs per gallon to 1.27 in 2026 and 1.28 in 2027, down from 1.6. The plan also scraps renewable electricity credits and limits foreign feedstock credits. RIN prices spiked—biomass-based credits hit $1.17, renewable fuel credits reached $1.06—signaling a $10 billion market boost.

Who’s Feeling the Impact?

America’s 2 million farmers, especially in Iowa’s corn belt, are pumped—biofuel demand could lift corn prices 10%, adding $5 billion to incomes. Ethanol plants expect 15% output growth, creating 1,000 rural jobs. Oil refiners, blending 80% of U.S. fuel, face $2 billion in extra RIN costs. Small refineries, with exemption pleas pending, could save $500 million if spared, but the EPA’s mulling 0-18 billion gallons in waivers. Consumers, pumping 140 billion gallons of fuel yearly, might see pump prices rise 5 cents.

Why It’s Awesome?

This is a rural game-changer! The plan cuts U.S. oil imports by 140,000 barrels daily, saving $5 billion yearly. Biomass diesel’s 5.61 billion gallons in 2026, up 67% from 2025, revives shuttered biodiesel plants. An oil-biofuel coalition’s push for 5.25 billion gallons shows rare unity.

Why It Matters?

Biofuels power 7% of U.S. fuel, supporting 400,000 jobs and $30 billion in GDP. With 35.6 billion tonnes of CO2 spewed globally, the EPA’s push could cut U.S. emissions by 50 million tonnes yearly. The $15 billion RIN market, up 20% in trades, balances oil and farm tensions. But oil refiners claim mandates risk 10 refinery closures and 5,000 jobs. The plan aligns with 70% of rural voters’ energy security hopes, promising a boost for America’s heartland.

What’s Next?

The EPA’s rule, open for public comment, heads to finalization by late 2025. Small refinery exemptions could shift 10% of mandates. Corn ethanol stays flat at 15 billion gallons, but advanced biofuels like sustainable aviation fuel could hit 1 billion gallons by 2027.
