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. The company intends to also report equity greenhouse gas emissions in future years and has undertaken the collation of this data from nonoperated joint ventures in which it has a 20 percent or greater equity interest or from joint ventures in which our equity share of GHGs equal or exceed 50,000 metric tons on a CO2 equivalent basis, regardless of equity ownership percentage.
ConocoPhillips reported total greenhouse gas emissions include carbon dioxide (CO2) emissions from operations (which includes the emissions associated with electricity and steam sold by the company), CO2 emissions from purchased electricity, CO2 emissions from purchased steam, and methane (CH4) emissions from operations in terms of CO2 equivalent. Carbon dioxide from operations, the major component of total GHG emissions, includes emissions from process operations such as exhaust from combustion sources and vented CO2. The scope of CO2 reporting does not include emissions associated with products sold and company-operated transports, except for marine vessels.
Additional gases that are considered GHGs under the Kyoto Protocol are accounted for by the company but are not included in the total greenhouse gas emissions reported because such emissions are negligible. Businesses have reported small quantities of nitrous oxide (N2O) and sulfur hexafluoride (SF6) from their operations. Businesses report no emissions of the other Kyoto gases hydrofluorocarbons (HFC) and perfluorocarbons (PFC).
Reported greenhouse gas emissions do not include any adjustments for intracompany transfer of steam and electricity generated by one plant and transferred to another. Therefore, CO2 from imported electricity and steam reported by the receiving plant also was accounted for by the plant which exported it. This condition exists in two known situations with the potential of 1.25 million metric tons of GHG emissions being counted by two operated facilities. This represents 2 percent of total company GHG emissions. A method of accounting for intercompany transfers is being considered.
