April biodiesel consumption grows compared to last year

Cellulosic and biomass-based diesel (D3 and D4) blending must expand to meet proposed mandates

The Environmental Protection Agency (EPA) reported 1.61 billion gallons of renewable fuel consumed during April, down seven percent from March but six percent above April 2021. Renewable Fuel Standard (RFS) credit generation of 1.7 billion RINs was seven percent below March but eight percent over April 2021. Reduced ethanol blending overshadowed increased consumption in the other “D” categories during April.

Biomass-based diesel (D4) consumption of 313.6 million gallons was two percent above March and 27 percent over April 2021. Within the D4 category, monthly biodiesel use increased 10 percent, renewable diesel consumption fell two percent, and renewable jet fuel blending was 89 percent lower.

April advanced biofuel (D5) blending of 12.8 million gallons edged one percent over March while RIN production was two percent higher. Increased renewable diesel and naphtha blending helped to lift the category during April.

The D6 conventional renewable fuel category, commonly referred to as ethanol production, fell nearly 11 percent to 1.1 billion gallons during April but was fractionally above April of 2021. Within the category, March ethanol blending was 10.6 percent below March while foreign generated D6 renewable diesel was 10 percent lower.

April cellulosic (D3) blending of 50.4 million gallons was 13 percent above March and 15 percent over April of 2021. Increased RNG blending and the re-emergence of cellulosic blending led the D3 category higher for the month.

Based on market feedback received and data collected, Fastmarkets has changed the free fatty acids (FFA) content to a maximum of 5% and iodine value (IV) to a minimum of 70 grams of iodine/mercury (hg), to reflect a specification used more commonly in the market.

An incorrect EUR/USD exchange rate, used to convert the cost of inputs priced in euros to US dollars, caused the prices to be calculated incorrectly. This has now been rectified.

Prices for European biofuel feedstocks from the Annex IX A and B list, including animal fats, used cooking oil (UCO) and soap stock acid oil (SSAO), showed a wide range of volatility during 2025, according to Fastmarkets’ assessments, with levels fluctuating by $152.50 per tonne (16.5%) on average.
Crude palm oil (CPO) futures rebounded from three days of losses to recover to its highest in three weeks on Friday January 16, spurred by gains across the broader vegoil complex and pre-weekend positioning while further indications of a slowing pace of production also lent support.
These changes are based partly on market feedback and on changes to regional production and SAF flows to Chicago and Los Angeles. Additionally, the calculations for feedstock production volume loss have been updated with market feedback. The new calculation assumes maximized SAF output at a hydrotreated esters and fatty acids (HEFA) production facility, and so […]
