New edition of greenhouse gas estimation methods – API

WASHINGTON, September 9, 2009 – API published a new edition of its guide for estimating greenhouse gas (GHG) emissions. The updated API Compendium of Greenhouse Gas Emissions Estimation Methodologies for the Oil and Natural Gas Industry (known as the Compendium) provides oil and natural gas companies with standardized methodologies for estimating carbon dioxide and other GHG emissions from all commonsources, such as combustion, venting, and fugitive, throughout the entire oil and natural gas value chain.  Although the methods are aimed at oil and natural gas operations, many have direct applicability to other sectors, especially those pertaining to GHG emissions from combustion sources.     

The ability to accurately estimate GHGs is critical to tracking progress toward reducing emissions.  “Unless there’s a consistent, reliable way to measure GHG emissions, it’s hard to assess progress,” said API’s Karin Ritter who led the industry team that updated the Compendium.  “API has been cataloging estimation methods for a decade.  Ideally these industry best practices for quantifying GHG emissions would be reflected in emerging regulatory and voluntary GHG programs."

The Compendium is one of a suite of tools for estimating emissions in the oil and natural gas industry provided by API.  Besides the Compendium, other tools include software for emissions estimation and inventory guidelines (created in conjunction with the International Petroleum Industry Environmental Conservation Association) to assist in the accounting and reporting of GHG emissions.

All of the tools are available at no charge on API’s website.
