Agriculture, Forestry and Other Land Use (AFOLU)
Pete Smith,Mercedes M. C. Bustamante,Helal Ahammad,Harry Clark,Hongmin Dong,Elnour A. Elsiddig,Helmut Haberl,Richard J. Harper,Joanna Isobel House,Mostafa Jafari,Omar Masera,Cheikh Mbow,N. H.

TL;DR: Agriculture, Forestry, and Other Land Use (AFOLU) is unique among the sectors considered in this volume, since the mitigation potential is derived from both an enhancement of removals of greenhouse gases (GHG), as well as reduction of emissions through management of land and livestock as discussed by the authors.
Journal ArticleDOI
Well-to-wheels energy use and greenhouse gas emissions of ethanol from corn, sugarcane and cellulosic biomass for US use
TL;DR: In this article, the authors present results from their most recently updated simulations of energy use and GHG emissions that result from using bioethanol made from several feedstocks: corn, sugarcane, corn stover, switchgrass and miscanthus.

Process Design and Economics for the Conversion of Lignocellulosic Biomass to Hydrocarbons: Dilute-Acid and Enzymatic Deconstruction of Biomass to Sugars and Biological Conversion of Sugars to Hydrocarbons
Ryan W. Davis,Ling Tao,Eric C. D. Tan,Mary J. Biddy,G. T. Beckham,C. Scarlata,J. Jacobson,K. Cafferty,Jeff Ross,J. Lukas,Daniel B. Knorr,P. Schoen +11 more
TL;DR: One potential conversion process to hydrocarbon products by way of biological conversion of lingnocellulosic-dervied sugars was described in this paper, which converted biomass to a hydrocarbon intermediate, a free fatty acid, using dilute-acid pretreatement, enzymatic saccharification, and bioconversion.
Journal ArticleDOI
Using Attributional Life Cycle Assessment to Estimate Climate-Change Mitigation Benefits Misleads Policy Makers
TL;DR: In this paper, a conceptually superior approach, consequential LCA (CLCA), avoids many of the limitations of ALCA, but because it is meant to model actual changes in the real world, CLCA results are scenario dependent and uncertain.
Journal ArticleDOI
Techno‐economic analysis and life‐cycle assessment of cellulosic isobutanol and comparison with cellulosic ethanol and n‐butanol
TL;DR: In this paper, the authors present a detailed analysis of the production design and economics of the cellulosic isobutanol conversion processes and compare them with n-butanol in the areas of fuel properties and engine compatibility, fermentation technology, product purification process design and energy consumption, overall process economics, and life cycle assessment.

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change
Tim Searchinger,Ralph E. Heimlich,Richard A. Houghton,Fengxia Dong,Amani Elobeid,Jacinto F. Fabiosa,Simla Tokgoz,Dermot J. Hayes,Tun-Hsiang Yu +8 more
TL;DR: This article found that corn-based ethanol, instead of producing a 20% savings, nearly doubled greenhouse emissions over 30 years and increased greenhouse gases for 167 years, by using a worldwide agricultural model to estimate emissions from land-use change.
Journal ArticleDOI
Land Clearing and the Biofuel Carbon Debt
TL;DR: Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuel reductions would provide by displacing fossil fuels.
Journal ArticleDOI
System boundaries and input data in consequential life cycle inventory analysis
Tomas Ekvall,Bo Pedersen Weidema +1 more
TL;DR: In this paper, a comprehensive presentation of the consequential approach to system boundaries, allocation and data selection is presented, based on a text produced within the SETAC-Europe working group on scenarios in consequential life cycle assessment (LCA).
ReportDOI
Life cycle inventory of biodiesel and petroleum diesel for use in an urban bus. Final report
TL;DR: A study of the life cycle inventories for petroleum diesel and biodiesel is presented in this paper, where the authors present information on raw materials extracted from the environment, energy resources consumed, and air, water, and solid waste emissions generated.
