Subpart W XML Reporting Help

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 2022; until then Version 11.0 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 RY2021 XML reporting schema (version 12.0) only includes those data elements applicable to RY2021 reporting. EPA has limited this file to just those data elements applicable to 2021 to clarify requirements and to assist facilities in preparing their 2021 reports.  To see the full XML schema for all subparts, all reporting years, and a change log comparing RY21 to RY20, please see the XML Reporting Instructions page.

An archive of  RY2015, RY2016, RY2017, RY2018, RY2019, and RY2020 XML reporting instructions can be found 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 

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.
