Cornerstone is a sustainability data initiative that maintains and publishes key US environmental datasets, including the US Environmentally-Extended Input-Output (USEEIO) family of models, the U.S. EPA's GHG Emission Factors Hub, and eGRID electricity emission factors, originally developed by the U.S. Environmental Protection Agency (EPA). USEEIO provides open emission factors across more than 400 sectors of the US economy and is widely used for Scope 3 corporate accounting, policy analysis, and academic research. The GHG Emission Factors Hub provides emission factors for a wide range of fuels, transportation modes, refrigerants, waste, and other activities commonly used in greenhouse gas inventories. eGRID provides detailed electricity generation emissions data for estimating the emissions intensity of grid-supplied electricity in the United States.

ecoinvent is a Swiss not-for-profit association that provides a Life Cycle Inventory (LCI) database that supports various types of sustainability assessments. This data enables users to gain a deeper understanding of the environmental impacts of their products and services. ecoinvent provides multiple climate impact indicators. We use "IPCC 2007 (superseded), climate change, global warming potential (GWP100)" for AR4 CO2e emisison factor values and "IPCC 2013, climate change, global warming potential (GWP100)" for AR5 values.

The Environmental Protection Agency (EPA) is the United States government agency that provides regularly updated default emission factors for organisational greenhouse gas reporting in the United States.
