Impact of second‐generation biofuel agriculture on greenhouse‐gas emissions in the corn‐growing regions of the US
Abstract
In the US, 95% of biofuel is produced from corn (Zea mays L), an intensively managed annual crop that is also grown for food and animal feed. Using the DAYCENT model, we estimated the effects on ecosystem services of replacing corn ethanol feedstocks with the perennial cellulosic feedstocks switchgrass (Panicum virgatum L) and miscanthus (Miscanthus × giganteus Greef et Deuter). If cellulosic feedstocks were planted on cropland that is currently used for ethanol production in the US, more ethanol (+82%) and grain for food (+4%) could be produced while at the same time reducing nitrogen leaching (−15 to −22%) and greenhouse‐gas (GHG) emissions (−29 to −473%). The GHG reduction was large even after accounting for emissions associated with indirect land‐use change. Conversion from a high‐input annual crop to a low‐input perennial crop for biofuel production can thus transition the central US from a net source to a net sink for GHGs.

“According to studies conducted over the last 15 years, advanced lignocellulosic bioenergy crops like miscanthus have the potential to cut GHG emissions more effectively than corn (Anderson- Teixeira et al., 2009; Davis et al., 2012; Hudiburg etal.,2015; Von Hellfeld etal.,2022).”

“…argument against the use of biofuel is based on the perception that food crops will be displaced by fuel feedstocks to land that was previously uncultivated or under different use (Searchinger et al. 2008), causing greenhouse-gas (GHG) emissions that offset the benefits of low-emission biofuels.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
