Ultra-Low Carbon Biodiesel

Crimson is California’s largest producer of ultra-low carbon biodiesel. Our BQ-9000 Accredited plant produces fuel that exceeds ASTM D6751 specifications, and meets individual end-user and terminal specifications year-round. Crimson’s biodiesel is a cleaner-burning fuel that significantly reduces carbon emissions while helping boost the longevity and performance of diesel engines.

What is ultra-low carbon biodiesel?

Biodiesel is a “drop in” diesel fuel that can be used in any diesel engine, typically in blends with petroleum-based diesel fuel.

Ultra-low carbon biodiesel is an advanced biofuel that achieves less than 20g CO2e/MJ via California’s Low Carbon Fuel Standard. Crimson’s biodiesel releases 80% less carbon than petroleum diesel.

Renewable Fuel

Crimson biodiesel turns waste – inedible animal fats, used oils like cooking greases and vegetable oils – into renewable, ultra-low carbon biodiesel.

Reduces Harmful Pollutants

The higher the percentage content of biodiesel (B20 vs. B5), the greater the reduction in CO, CO2, hydrocarbons, particulate matter emissions, and carbon output.

Increases Energy Independence

American-made, renewable fuel reduces dependence on foreign oil and fuels.


Biodiesel contains no hazardous materials and it biodegrades faster than diesel. Its use is preferred in environmentally sensitive areas.


Equipment or engine modifications are not necessary. Biodiesel can be stored in existing diesel fuel tanks and pumped with existing equipment.

Improves Lubricity

High solvent and lubricity properties of biodiesel reduce wear and extend component life compared to ultra-low sulfur diesel.
