Carbon Calculator for Land Use and Land Management Change from Biofuels Production (CCLUB)
Abstract: CCLUB has been developed as an integral part of Argonne’s GREET model to analyze GHG emissions from land use change (LUC) and land management change (LMC) in the context of overall biofuel life-cycle analysis. It relies on biofuel production scenarios, LUC and LMC scenarios, and emission factors (EF) to generate GHG emissions of LUC and LMC for biofuel production in gCO2e per MJ of fuel produced. In response to biofuel production scenarios of four ethanol and one soy biodiesel pathways, the GTAP model estimates domestic and international area of land that transits from one of four land use types to
another. Then the area changed due to land transition is multiplied by corresponding EFs to estimate LUC GHG emissions for biofuel production scenarios. While both domestic and international EFs are derived from an empirical database resolved at the biome or U.S. state-equivalent level, CCLUB utilizes county-level domestic soil C EFs generated with a process-based simulation model (parameterized CENTURY). CCLUB also estimates domestic soil C EFs associated with LMC scenarios, which include conservation farming options practiced when corn stover is harvested as cellulosic ethanol feedstock.
