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 check, and XML reporting examples for each Subpart W Segment.   These schema will go into effect in mid-February 2018; until then Version 7.1 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

For RY2014 and prior years,  please see the previously published RY2014 XML help document:

An archive of  RY2012, RY2013, RY2014, RY2015, and RY2016 XML reporting instructions can be found at Archived XML Reporting Instructions.
