| Much research has provided estimates of induced land use change and emissions for first generation biofuels. Relatively little has estimated land use change for the second generation cellulosic biofuels. In this paper we estimate induced land use change and emissions for these biofuels. Estimated emissions due to land use changes induced by biofuels production are uncertain not only because their associated land use changes are uncertain, but also because of uncertainty in the land use emissions factors (EFs). This paper also examines uncertainties related to these EFs and their assumptions. Three emissions factors including EFs obtained based on Woods Hole (WH) data, EFs developed by California Air Resources Board (CARB), and EFs obtained from the... |

| The passage of U.S. laws mandating and subsidizing advanced cellulosic biofuels may spur the development of a commercial cellulosic biofuels industry. However, a cellulosic industry will only develop if the overall economics including government incentives render investment in the sector attractive to private investors. This study compares the profitability of three biofuel production types: grain based ethanol, cellulosic biochemical ethanol, and cellulosic thermochemical biofuels. In order to compare the current profitability of each of the production types, the Biofuels Comparison Model (BCM) was developed. The BCM is a spreadsheet model that estimates the net present value (NPV) for each production type given input and output prices, technical,... |
