APPLICATION OF THE API COMPENDIUM OF GREENHOUSE GAS EMISSIONS ESTIMATION METHODOLOGIES FOR THE OIL AND GAS INDUSTRY TO EXAMINE POTENTIAL EMISSION REDUCTIONS

摘要

In response to continued interest by its member companies about consistency in greenhouse gas (GHG) emissions estimation, the American Petroleum Institute (API) developed a Compendium of Greenhouse Gas Emissions Estimation Methodologies for the Oil and Gas Industry. Initially distributed in June 2001, the Compendium is a result of more than a year long effort by API to screen, evaluate and document a range of calculation techniques and emission factors that could be useful for developing GHG emissions inventories. In a continued effort to enhance the real-world application of the Compendium, API is examining the applicability of the Compendium methodologies to assess emission reductions from specific projects. This paper presents findings from this follow-on activity. Although the reduction activities presented may not be applicable to all locations, and the estimated emission reductions may not be achievable for all situations, the purpose of this study is to illustrate use of the Compendium and identify potential methodological issues. This paper examines technical considerations associated with estimating pre- and post-project emissions and discusses the criteria being set forth in the international community regarding requirements for reliable emission reduction projects.
