The HSE metrics presented in this report are based on the following assumptions:
In the environmental, safety and spills data tables in this appendix, data are presented for three geographic regions: North America, Europe and Asia Pacific/Other. “Other” includes Venezuela, Middle East and Africa. The top contributing business sectors columns show the top three sectors in the company for that parameter, plus a category named “Other,” which includes all other sectors combined. For each indicator, the top three sectors may be different, as can the sectors in the “Other” category.
The HSE pro forma data for 2002 is presented as if the Conoco/Phillips merger had occurred on January 1, 2002.
Data reflecting operation of Burlington Resources assets in the United States, Canada, China, United Kingdom and Algeria are included for nine months of 2006, as these assets were acquired March 31, 2006. Data reflecting operation of the Wilhelmshaven refinery in Germany are included for 10 months of 2006, as this asset was acquired in February 2006.
All reported HSE data are based on operated assets only. Environmental data are represented as 100 percent ownership interest regardless of actual share owned by ConocoPhillips. Data is reported in metric tons.
Reported data for air emissions, hydrocarbon spills and waste are broken down into two business sectors: Exploration and Production (E&P) and Midstream, and Refining and Marketing (R&M). Select environmental data for 2003 through 2006 is provided.
Total E&P and Midstream emissions are normalized using barrels of oil equivalent (BOE) as a factor of production operations. For gas production and liquefied natural gas, 6,000 cubic feet of gas is assumed to be equal to one BOE. For gas processing plants, the BOE normalizer includes only liquid production of ethane, propane, butane and condensate.
The R&M normalized data are presented for refining only, which is the major sector of R&M operations. Refining data are normalized based on million barrels of oil equivalent (MMBOE), which represents the number of barrels of crude oil and other hydrocarbon feedstock input to the refineries.
Various restatements to previously reported data for prior years have been reflected to provide the most accurate data. For example, carbon dioxide emissions that are contractually owned, but do not result from assets operated by the company, were included in prior years. All periods have been restated to exclude these emissions from our accounting of operated emissions and are being accounted for as equity emissions, which will be included in future reports.
