An overview of the US EPA Emissions Factor Source
Summary
The US Environmental Protection Agency publishes a variety of emissions factors across Scope 1, 2 and 3 with the majority of materials summarised under the EPA’s GHG Emission Factors Hub. The Hub draws from published material by the EPA and other governmental departments.
The Emissions Factor Hub is used widely by US based organisations voluntarily reporting on their emissions and is a key source in the proposed mandatory reporting frameworks.

Sumday Take | The US EPA emission factors are widely regarded as one of the most credible emission factor sources. The factors are used by US based operations to quantify their emissions and are often used in jurisdictions where the local government does not publish their own emissions factors. Despite being relatively comprehensive the US EPA lacks coverage of some emission categories such as leased assets and working from home. As a result these EFs may need to be supplemented with other data sources to prevent inventory gaps. |
