U.S. imports of biomass-based diesel, which include biodiesel and renewable diesel, grew 12% in 2020 to more than 31,000 barrels per day (b/d), increasing for the second consecutive year. Imports of biomass-based diesel increased in 2020 because of growing demand to meet government renewable fuel programs. U.S. consumption of biomass-based diesel, unlike demand for other fuels, remained relatively unaffected by responses to COVID-19 during 2020.
