NEW YORK -The Trump administration on Friday proposed to increase the amount of biofuels that oil refiners must blend into the nation’s fuel mix over the next two years, and included a surge in biomass-based diesel mandates.

The U.S. Environmental Protection Agency proposed on Friday total biofuel blending volumes at 24.02 billion gallons in 2026 and 24.46 billion gallons in 2027. That compares with blending requirements of 22.33 billion gallons in 2025.
