Spatial and Temporal Analysis of Land Use Disturbance and Greenhouse Gas Emissions From Canadian Oil Sands Production

摘要

We collect geospatial information on actual pre-and-postland use changes data from 1985 to 2009, and provideupdated values of GHG emissions associated with oil sandsland use disturbance into the Greenhouse gases, RegulatedEmissions, and Energy use in Transportation (GREET) Modelby Argonne National Laboratory.The production-weighted average LUI (gross) value acrossall sites for the entire period (1985-2009) is 0.648 m~2/m~3 forsurface mining and 3.57 m~2/m~3 for in-situ projects. Theproduction-weighted average LUI (net) value across all sitesfor the entire period (1985-2009) is 0.598 m~2/m~3 for surfacemining.We found that the production weighted land use carbonintensities were 3.38-3.43 gCO2e/MJ for surface mining(excluding Horizon) and 1.78–2.80 gCO2e/MJ for in-situproduction.
