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 2024, the e-GGRT XML Schema Version 14.0 must be used for any XML-based reporting (RY2018 through RY2023).  e-GGRT XML Schema v14.0 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

• e-GGRT XML Reporting Schema RY2023 - v14.0 (zip, 10/031/2023) (237k)
  • Comparison Report - v13.2 vs v14.0  (zip, 10/31/2023) (27k)
  • Schema Change Log - v13.2 vs v14.0  (xlsx, 10/31/2023) (12k)
• IVT Inputs XML Schema RY2023 - v5.0 (zip, 10/30/2023) (36k) 

Until mid-February 2024, XML-based submissions should be formatted based on Version v13.2 of the schema.  This version of the schema and related XML reporting instructions can be found at Archived XML Reporting Instructions.
