U.S. biodiesel and renewable diesel producers are working to extend fuel supplies and provide relief at the pump to American families, according to a letter from Clean Fuels Alliance America sent to President Joe Biden, administration officials, and congressional leaders this week.

“Our industry is investing billions to expand production of biodiesel, renewable diesel, and sustainable aviation fuel to further extend consumer access to clean fuels. Our partners in the agriculture industry are investing more than $4 billion to expand the supply of renewable oils for both food and clean fuels,” the letter states. “U.S. biodiesel and renewable diesel producers are supplying more than 3.2 billion gallons of cleaner, better fuel to the U.S. market, meeting more than 5% of the nation’s demand for on-road heavy-duty fuels. These fuels are essential to keeping food and other consumer items moving across the country and are keeping diesel prices from rising even higher during the current shortage.”

The letter further highlights a recent study from the World Agricultural Economic and Environmental Service showing that U.S. biodiesel and renewable diesel production generates a 4 percent decrease in the price of diesel fuel.

The letter also thanks the administration for recent actions to grow Renewable Fuel Standard volumes for advanced biofuels and biomass-based diesel and provide additional infrastructure grants to improve consumer access to biodiesel.
