Stakeholder Webinar (Nov. 2022): Natural Gas & Petroleum Systems in the GHG Inventory

On November 29, 2022, EPA held a stakeholder webinar on EPA’s GHG data for natural gas and petroleum systems from the GHG Inventory and the Greenhouse Gas Reporting Program (GHGRP).

At the webinar, EPA presented on GHGRP data, and on existing GHG Inventory methods and updates under consideration. Stakeholders also presented on new data and information relevant to estimating GHG emissions from natural gas systems and petroleum systems.

Subsequent to the webinar, EPA developed a memo that expanded on information presented during the webinar and that supported the public review draft of the Inventory. This memo is available below, along with the webinar slides.

Memo
