Six trade associations wrote a letter to the White House asking President Trump to unleash U.S. biodiesel and renewable diesel production to bolster America’s energy security during the Iran conflict. The disruption in the global oil market is constraining diesel fuel supplies, which threatens to raise the cost of all U.S. consumer goods and further harm the U.S. agriculture sector as farmers start the season’s planting. Immediately finalizing the 2026 and 2027 Renewable Fuel Standards would encourage the U.S. fuel industry to quickly ramp up enough production capacity to meet three percent of the nation’s demand for diesel. The letter was signed by Clean Fuels Alliance America, the American Soybean Association, and many other groups. “The biodiesel, renewable diesel, and the SAF industry is ready to meet the challenge of providing crucial supplies of diesel fuel free from overseas threats,” the groups wrote in the letter.
