The U.S. EPA has released decisions affecting the Renewable Fuel Standard (RFS) for 2026-2027, resulting in higher renewable volume obligations (RVOs) and stricter small refinery exemptions. The elimination of the half-RIN provision, which restricts imported biofuel and feedstock to 50 percent of domestic RINs, is anticipated.

Projections for biomass-based diesel production and feedstock use reflect these changes. RVOs are updated based on multiple EPA rulemakings, including proposed RVOs, small refinery exemptions, and a new methodology for obligated petroleum volumes. Two reallocation scenarios for small refinery exemptions are considered: 100 percent and 50 percent.
