# Rewriting the RFS Playbook: The Coming Battle over the 2027 Biomass-Based Diesel RVOs

> Louisiana Governor Jeff Landry and Alabama Governor Kay Ivey asked EPA Administrator Lee Zeldin for a partial waiver of the 2027 Renewable Fuel Standard requirements, calling it targeted, prospective and temporary. Biofuel and farm groups quickly urged EPA to reject the petitions, and Landry has urged other Southern governors to join. Gasoline and diesel use is tracking below EPA's 2026 projections, and EPA has proposed reallocating exempted 2025 volumes into 2026 and 2027.

## Why it matters

A waiver or reallocation would reduce the biomass-based diesel volume that refiners must blend, weakening demand for soybean oil and other feedstocks used in biodiesel. Lower D4 RIN demand would be bearish for soybean oil prices, while a rejected petition would support them.
