| Abstract | Releases of greenhouse gases (GHG) from indirect land-use change triggered by crop-based biofuels hate taken center stage in the debate over the role of biofuels in climate policy and energy security. This article analyzes these releases for maize ethanol produced in the United States. Factoring market-mediated responses and by-product use into our analysis reduces cropland conversion by 72% from the land used for the ethanol feedstock. Consequently; the associated GHG release estimated in our framework is 800 grants of carbon dioxide per megajoule (MJ); 27 grants per MJ per year, over 30 years of ethanol production, or roughly a quarter of the only other published estimate of releases attributable to changes in indirect land use. Nonetheless, 800 grants are enough to cancel out the benefits that corn ethanol has on global warming, thereby limiting its potential contribution in the context of California's Low, Carbon Fuel Standard. |
