This graph shows renewable diesel fuel as tracked by the Renewable Identification Numbers (RINs) volume generated. Renewable diesel meets the same fuel quality specification as petroleum diesel (ASTM D975) and can be used in existing diesel engines and refueling infrastructure. This volume is reported to the Environmental Protection Agency (EPA) as part of the Renewable Fuel Standard (RFS) program. Domestic production and plants under construction are growing significantly. Renewable diesel is primarily made from used cooking oil and inedible animal fats left over from processing meat. The fuel is used primarily in California because of economic benefits provided under the Low Carbon Fuel Standard.
