XML Reporting Instructions

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 2025, the e-GGRT XML Schema Version 15.1 must be used for any XML-based reporting (RY2019 through RY2024).  e-GGRT XML Schema v15.1 is paired with the IVT Inputs XML Schema Version v5.0 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
