The petroleum industry has recognized the need for GHG accounting and reporting guidance that is focused specifically on its operations. To help meet this need, member companies of the American Petroleum Institute (API) first published the Compendium of Greenhouse Gas Emissions Estimation Methodologies for the Oil and Gas Industry in April 2001, with a third edition released in August 2009 (referred to as the Compendium). The original edition of this publication, Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions (referred to as the Guidelines) was issued in December 2003 to fulfil the need for industry guidance focused specifically on the accounting and reporting of GHG emissions at the facility through to the corporate level. This report is the first revision of the Guidelines.
API Tools for Estimating GHG Emissions
Accurate estimation of greenhouse gas emissions is indispensable to responsibly addressing climate change. Through API, the U.S. oil and natural gas industry has provided a suite of tools for estimating emissions. It includes API's 2009 compendium of emissions estimation methodologies, software for emissions estimation and inventorying, and guidelines (created by the international petroleum organization IPIECA) to assist in the accounting and reporting of emissions.
