XML Reporting Documentation

Below you will find three type of technical assistance for the Subpart W XML reporting community:  schema and XML requirements documentation, documentation addressing critical validation checks, and XML reporting examples for each Subpart W Segment.   These schema will go into effect in mid-February 2025; until then Version 14.0 of the schema remains applicable. While these will address a wide range of questions, users that continue to have difficulty configuring, uploading, or submitting their Subpart W XML are urged to contact the GHGRP Help desk by e-mail at GHGReporting@epa.gov.

Schema and XML Requirements

The Subpart W RY2024 XML reporting schema (version 15.1) includes data elements applicable to RY2024 reporting. EPA has limited the Subpart W Enumerations and Xpath Requirements documentation to those data elements applicable to 2024 to clarify requirements and to assist facilities in preparing their 2024 reports.  Beginning RY2024, facilities that report Subpart W are also subject to new reporting requirements for Subpart A.   To see the full XML schema for all subparts, all reporting years, and a change log comparing RY2024 to RY2023, please see the XML Reporting Instructions page.

Critical Validation Checks

Subpart W has over 600 critical validations checks.  To help XML reporters determine with specific data element is causing critical validation, we have provided that documentation below:

XML Reporting Examples 

This section provides examples of common Subpart W reporting scenarios and XML submissions demonstrating how annual GHG reports should be structured. In each case we have provided a complete segment report which includes all sources applicable to the segment.  Each example is presented in a Reporting Form format and in an XML for consistent with the formats created by and expected by e-GGRT.
