This document was designed to provide organizations with a regularly updated and easy-to-use set of default emission factors for organizational greenhouse gas reporting. The document includes updated emission factors collated from both EPA's Greenhouse Gas Reporting Program and Climate Leaders technical guidance. The most recent version of the Emission Factors Hub (April 2014) includes updates to emission factors for stationary and mobile combustion sources, new electricity emission factors from EPA's Emissions & Generation Resource Integrated Database (eGRID), and Global Warming Potentials (GWPs) from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4).
