Q728. Does EPA archive past versions of the GHGRP data set?
A728. Yes. Reporters subject to the GHGRP are free to re-submit their reports at any time as errors are identified and corrected. EPA refreshes the data available in Envirofacts, FLIGHT and the associated downloadable files periodically. Past versions of the summary GHG files are available under the "Data Archive" tab at http://www.epa.gov/ghgreporting/ghg-reporting-program-data-sets. For past versions of other files, please contact us.
