EPA has developed an XML reporting schema that allows facilities to upload their greenhouse gas (GHG) data directly in lieu of using the web forms provided through the Electronic Greenhouse Gas Reporting Tool (e-GGRT).
Starting in mid-February 2019, the e-GGRT XML Schema Version v9.1 must be used for any XML-based reporting (RY2013 through RY2018). e-GGRT XML Schema v9.1 is paired with the IVT Inputs XML Schema Version v4.0 which defines requirements for inputs files submitted in XML format. For XML documentation specific to Subpart W please refer to Subpart W XML Reporting Help
