Frequently Asked Questions
Understanding Advanced Biofuels
Definition: Advanced biofuels are liquid fuels primarily derived from non-food-based feedstocks, offering a lifecycle reduction in greenhouse gas (GHG) emissions of at least 50% compared to fossil fuels.
Source: Massachusetts Department of Energy Resources
Types of Feedstocks:
- Fats, Oils, and Greases: From agricultural products like soybean oil to specialty grasses and cover crops, tall oil, and used cooking oil.
- Cellulosic Material: Includes municipal solid waste, wood, and agricultural residues.
- Gaseous Waste Streams: Renewable gases sourced from wastewater treatment plants, bio-digesters, landfills, and industrial facilities via carbon capture.

Benefits of Advanced Biofuels
- Greenhouse Gas Emission Reduction:
- A minimum 50% reduction in GHG emissions compared to fossil fuels.
Source: Massachusetts Department of Energy Resources
- Support for Low Carbon Fuel Standard (LCFS) in California:
- Assists the LCFS program in achieving a 30% reduction in carbon emissions by 2030.
Biodiesel Overview
Definition: Biodiesel is a renewable, biodegradable fuel produced domestically from vegetable oils, animal fats, or recycled restaurant grease. It meets the biomass-based diesel and overall advanced biofuel requirements of the Renewable Fuel Standard (RFS).
Benefits:
- Enhances energy security.
- Improves air quality and the environment.
- Provides safety benefits.
Renewable Diesel Overview
Definition: Renewable diesel is a fuel chemically identical to petroleum diesel, produced from fats and oils like soybean or canola oil.
Benefits:
- Significant emissions reduction compared to petroleum diesel.
- Enhanced flexibility in use and production.
- Compatible with existing infrastructure and diesel engines.
Biodiesel vs. Renewable Diesel
Difference: Renewable diesel and biodiesel are distinct fuels. Renewable diesel is a hydrocarbon often produced through hydrotreating, gasification, pyrolysis, and other technologies. In contrast, biodiesel is a mono-alkyl ester produced through transesterification.

Biodiesel Statistics:
- Production and Consumption:
- California's biodiesel production and consumption figures vary annually.
- Key biodiesel statistics may include production volumes, consumption trends, and market shares.
- Carbon Intensity Performance:
- Biodiesel's carbon intensity performance, measured in grams of CO2 equivalent per megajoule (gCO2e/MJ), is relevant under the LCFS.
- Greenhouse Gas Emissions:
- Biodiesel is known for reducing greenhouse gas emissions compared to traditional diesel.
- The reduction percentage can vary based on feedstock and production processes.
- LCFS Compliance Credits:
- Biodiesel producers can earn LCFS credits based on the carbon intensity of their product.
Renewable Diesel Statistics:
- Production:
- Renewable diesel production has been increasing in response to growing demand.
- Major producers include the United States, Europe, and Singapore.
- Carbon Intensity:
- Renewable diesel often boasts lower carbon intensity compared to traditional diesel.
- Some jurisdictions, like California with its Low Carbon Fuel Standard (LCFS), provide statistics on the carbon intensity benefits.
- Feedstock and Sources:
- Feedstock sources for renewable diesel include fats, oils, and greases.
- Statistics on the types of feedstock used can provide insights into the sustainability of production.
California's Low Carbon Fuel Standard (LCFS):
- Overview:
- The LCFS is a state policy aimed at reducing the carbon intensity of transportation fuels, including diesel and gasoline.
- It sets annual carbon intensity reduction targets, encouraging the use of low-carbon and renewable fuels.
- Biodiesel and Renewable Diesel:
- Biodiesel and renewable diesel are considered low-carbon alternatives under the LCFS.
- Both contribute to meeting the state's carbon reduction goals.
- Carbon Intensity Credits:
- Producers of low-carbon fuels, including biodiesel and renewable diesel, earn credits based on the carbon intensity of their products.
- These credits can be traded, providing an economic incentive for the use of low-carbon fuels.
- Reporting and Compliance:
- Fuel producers and importers are required to report the carbon intensity of the fuels they supply.
- Compliance involves meeting or exceeding the annual carbon intensity targets.
- Impact on the Market:
- The LCFS has played a significant role in promoting the use of alternative fuels and reducing the carbon footprint of transportation in California.
