# What is renewable diesel fuel?

Renewable diesel or renewable hydrocarbon diesel (also known as hydrotreated vegetable oil or HVO) is a relatively new fuel sometimes confused with biodiesel. Although sourced from the same oils and fats as biodiesel, renewable diesel is produced using a different process called hydrotreating. Most renewable diesel is used in California and along the West Coast, but the fuel is expected to grow as processing capacity increases throughout the country.

# Why is renewable diesel a Clean Air Choice®?

Renewable diesel is a cleaner burning and lower carbon fuel than petroleum diesel. While additional research is needed, initial testing shows that its emission and carbon reduction qualities are similar to biodiesel. Renewable diesel is made from renewable feedstocks, such as soybean oil, used cooking oil, and distillers corn oil (a byproduct of ethanol production).

# What are other benefits?

• Flexible. Renewable diesel is a drop-in replacement for petroleum diesel in existing equipment. It meets ASTM D975 standards for petroleum diesel fuel
• Efficient winter fuel. Renewable diesel resists gelling for cold weather operability
