Modeling Uncertainty Is Not a Reasonable Basis for Ignoring ILUC Emissions
July 14, 2009
Analysis by Tim Searchinger explains why modeling uncertainty does not logically or practically justify ignoring overseas emissions from the land use change associated with US biofuel production mandates.

Land Use-Related GHG Emissions from Biodiesel Production Overwhelm Climate Benefits
February 7, 2008
A Clean Air Task Force-supported study by Tim Searchinger and Ralph Heimlich looks at a critical but under-explored issue in biofuels and climate: the effect of increasing demand for arable land to grow biofuels crops. The study concludes that the carbon dioxide releases from land use change – that is, from the land clearing that is needed to support biofuel production – overwhelm the emissions reductions typically associated with biodiesel use. The biodiesel study is a companion piece to an article by Searchinger et al. that focuses on the land use-related climate impacts of ethanol production. The ethanol study was published in the journal Science on February 7, 2008.
