On December 28, 2021, EPA announced that it will hold a public virtual meeting to discuss biofuel greenhouse gas (GHG) modeling. EPA is soliciting information on the current scientific understanding of GHG modeling of land-based biofuels used in the transportation sector. According to EPA, the information gathered during this meeting will be used to inform current and future EPA actions, including the method for quantifying GHG emissions under RFS. Of particular interest to EPA, is input on:

• How to incorporate the best available science into an update of EPA’s biofuels lifecycle analysis (LCA); and

• The next steps EPA should take in this work area.

Hosted by EPA’s Office of Transportation and Air Quality in consultation with USDA and DOE, the virtual public meeting is scheduled for February 28, 2022, and March 1, 2022, from 12:00 p.m. to 4:00 p.m. (EST). EPA will also be accepting comments on these topics until April 1, 2022.
