The Trump administration unveiled long-awaited biofuels blending standards, imposing a stronger mandate than a plan proposed last year in a further show of support for producers and American farmers.

The rule requires refiners to mix a record 25.82 billion gallons of biofuels into conventional diesel and gasoline this year, almost 8% higher than was advertised last June, the Environmental Protection Agency said.
