Discussion on the Method of Carbon Emission Accounting in China’s Oil and Gas Production Process

China has formulated a clear carbon emission reduction target, for which all industries need to formulate a standardized carbon emission accounting system. However, most of the related researches in the field of oil production are aimed at the whole oil industry system. There is a lack of carbon emission accounting research applicable to each oil and gas production unit starting from the specific oil and gas production process. This paper analyzes the principle of the current general carbon emission accounting technology, and summarizes the carbon emission accounting specifications for the petroleum system. Based on the Greenhouse Gas Emissions Accounting Method Guidelines issued by China’s National Development and Reform Commission as a standard, the process of actual carbon emission accounting for specific oil and gas production units is simulated. And studies the problems existing in the actual carbon emission accounting. Through the research, it is concluded that: 1, At present, the carbon emission accounting method used in oil and gas production is improved from the census method, and the theory is formulated with clear specifications, but there are certain problems in the actual implementation.2,The oil and gas industry lacks accurate carbon emission factor parameters, and a case study of the full-process carbon emission accounting of typical projects should be carried out. 3, Most of the current publicly available data are calculated from old oil and gas production parameters, which most likely exaggerate the carbon emissions of China’s oil and gas industry.
