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 checkchecks, and XML reporting examples for each Subpart W Segment.   These schema will go into effect in mid-February 20202024; until then Version 1013.0 2 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

Schema and XML Requirements

The Subpart W RY2019 RY2023 XML reporting schema (version 1014.0) only includes those data elements applicable to RY2019 RY2023 reporting. EPA has limited this file to just those data elements applicable to 2019 2023 to clarify requirements and to assist facilities in preparing their 2019 2023 reports.  To see the full XML schema for all subparts, all reporting years, and a change log comparing RY19 RY23 to RY18RY22, please see the XML Reporting Instructions page. There were no XML schema changes for Subpart W between RY23 and RY22. 

An archive of  RY2012RY2017, RY2013RY2018, RY2014RY2019, RY2015RY2020, RY2016RY2021, RY2017 and RY2018 RY2022 XML reporting instructions can be found at at Archived XML Reporting Instructions.

Critical Validation Checks

Subpart W has almost 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 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.
