Fuel Quality Information

Ensuring consumers have a high level of confidence in the biodiesel they purchase is a top priority for the NBB and key element in the industry's continued growth.

Regulation of fuel standards is a function primarily left to the states. However, regulation of biodiesel and blends is not uniform across all states.

The NBB is undertaking a project to work with states to catalog information regarding their authority to regulate fuels; their status in adopting ASTM D6751 as the fuel specification for biodiesel; enforcement procedures; and to assess their capacity to analyze samples. Information gathered from this project will be presented on the State Fuel Quality Index page.

The NBB will continuously work with states to update information found on this page, as well as track their efforts in adopting ASTM D6751.
