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 2023; until then Version 12.0 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 RY2022 XML reporting schema (version 13.1) only includes those data elements applicable to RY2022 reporting. EPA has limited this file to just those data elements applicable to 2022 to clarify requirements and to assist facilities in preparing their 2022 reports. To see the full XML schema for all subparts, all reporting years, and a change log comparing RY22 to RY21, please see the XML Reporting Instructions page.

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
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.
