Abstract : Life-cycle analysis of greenhouse gas (GHG) emissions of petroleum fuels pathways requires careful accounting of GHG emissions from both process fuel combustion and non-combustion activities associated with crude oil production and storage, transportation, refining operations, distribution of fuels and their end use by vehicles. Vented, fugitive, and flaring (VFF) CH4 and CO2 emissions can be released to the atmosphere during crude oil production processes (U.S. Environmental Protection Agency, 2018). Argonne researchers regularly estimate such emissions for modeling petroleum-based fuel pathways in the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREETTM) model primarily based on the annual GHG Emission Inventory Report by United States Environmental Protection Agency (EPA). Recently, EPA has adopted new data and methodology to estimate CH4 and CO2 emissions for petroleum systems (U.S. Environmental Protection Agency, 2018). These revisions caused changes to the VFF CH4 and CO2 emissions from domestic crude oil production in the U.S. The aim of this technical memorandum is to update VFF CH4 and CO2 emissions in the GREET model by incorporating these revisions in the latest EPA GHG emission inventory.
