Title : Estimating emissions related to indirect peatland loss in Southeast Asia due to biofuel productionPublication Date : August 17, 2018
Authors : Z. Qin, H. Kwon
Abstract : ILUC stands for indirect land use change or induced land use change, which is normally accounted for its impact on biofuels’ greenhouse gas (GHG) emissions (Chen et al., 2018). Due to its complexity, the ILUC emissions are estimated using models involving area changes of specific land types and emission factors (EFs) for conversion of one land type to another. Without diving into too many details, one can identify two major “ILUC factors” determining the ILUC emissions, the ΔILUC which reflects the area of land that transits from one type of land use to another, and the EFs that determine specific (i.e., CO2, N2O and CH4) or total emissions (in terms of total GHG) per unit area changed associated with specific ILUC. It is critical to include both factors in ILUC emissions estimation. Here we show recent updates that are specifically related to ΔILUC and EFs for one of the ILUCs contributed to biofuels’ ILUC emissions, the forest-on-peat to palm transition in Southeast Asia (mainly Indonesia and Malaysia). Further, we incorporate such updates into the CCLUB module (aka. Carbon Calculator for Land Use change from Biofuels production) that used in the GREET® model to estimate ILUC impacts, and briefly discuss ILUC emissions associated with soy biodiesel production in the U.S.
