It’s official. The much-anticipated revisions to Subpart W of the Greenhouse Gas Reporting Program are here. In broad terms, the EPA has included new facility components and placed a renewed focus on empirical data over estimated emission factor calculations to improve the accuracy, transparency, and clarity of reporting total GHG emissions from Subpart W-applicable facilities. The revision further emphasizes a more accurate, and verifiable approach through the use of financial incentives to Operators who comply with the new requirements.
