GHG Management

Select GHG Advocacy and Emission-Management Efforts:

 Anadarko worked with industry, regulators, and the Environmental Defense Fund (EDF) to draft proposed and newly adopted air-quality regulations in Colorado to detect and address methane leaks.

Anadarko participated in a multi-stakeholder study in partnership with the EDF and other industry representatives published by the University of Texas (UT) in the Proceedings of the National Academy of Sciences reporting on methane emissions from natural gas production sites. This study conducted the first documented direct measurements at well completions and found that methane emissions were 97 percent lower than previously estimated by the EPA during this phase of development. 

Anadarko incorporates Best Management Practices (BMP) into our operations that reduce GHG emissions, including:

  • Broad usage of Forward-Looking Infrared (FLIR) technology for leak detection surveying and inefficient pipe replacement
  • Plunger lift, green and reduced-emission completions, and gas recovery system installation to reduce vented CH4
  • Solar-powered pumps to replace gas-fired pneumatic pumps
  • Replacement of older and less-efficient compressors
  • Increased usage of pipelines and water-management programs that eliminate truck traffic and their associated emissions

U.S. Federal GHG Required Reporting

On Oct. 31, 2010, the EPA issued the Final GHGRP requiring specific industry sectors and GHG emitters over 25,000 metric tonnes of CO2-equivalent to report emissions on an annual basis starting March 31, 2011, for the 2010 calendar year.  Anadarko is applicable to report to the GHGRP under the following subparts:

  • Subpart A: General Provisions
  • Subpart C: General Stationary Fuel Combustion Sources
  • Subpart W: Petroleum and Natural Gas Systems
  • Subpart NN: Suppliers of Natural Gas and Natural Gas Liquids
  • Subpart PP: Suppliers of Carbon Dioxide
  • Subpart UU: Injection of Carbon Dioxide

Because the GHGRP specifies calculation methods that must be used to estimate emissions, Anadarko will conduct GHG emission comparisons from year to year based upon reports submitted annually to the EPA. Anadarko’s GHG emissions, as reported to the EPA, may be found on the EPA website.

Anadarko also has reported GHG emissions data and additional comprehensive information regarding our carbon-management strategies and actions to the Carbon Disclosure Project (CDP) annually since 2005. Further information is available on the Carbon Disclosure Project website.
