EPA to Host Biofuel Greenhouse Gas Modeling Workshop

The Environmental Protection Agency (EPA) is hosting a virtual public workshop on biofuel greenhouse gas (GHG) modeling February 28 – March 1.

This workshop seeks to solicit information on the current scientific understanding of greenhouse gas modeling of land-based biofuels and how this information can be applied to a range of current and future actions. EPA is explicitly seeking comment on the following questions: 1) what sources of data exist and how can they be used to inform the assumptions that drive GHG estimates; 2) how best to characterize the sources of uncertainty associated with quantifying the GHG emissions associated with biofuels; and 3) what model(s) are available to evaluate the lifecycle GHG emissions of land-based biofuels, and do the model(s) meet the Clean Air Act requirements for quantifying the direct and significant indirect emissions from biofuels.

The information gathered through the workshop will be used by EPA for quantifying the greenhouse gas emissions under the Renewable Fuels Standard, including how to incorporate the best available science into updating the lifecycle analysis (LCA) used for biofuels, and “what steps EPA should take next in this work area.”

Due to the COVID-19 pandemic, this workshop will be held virtually only using Zoom.
