Carbon emission accounting methods and issues for oil and gas production process
Currently,most of the carbon emission accounting research related to oil and gas production is focused on the oil and gas industry,and there is a lack of research on carbon emission accounting that is developed from the perspective of basic oil and gas production processes and is suitable for individual oil and gas production units.This article analyzes the principle behind existing commonly used carbon emission accounting techniques and summarizes the carbon emission accounting procedure applicable to oil and gas industry.Taking the Guidelines for Accounting and Reporting Greenhouse Gas Emission for CNPC Nabural Gas Production Companies(Trial)issued by the National Development and Reform Commission of China as an example,a simple production simulation model was developed for actual carbon emission accounting process of oil and gas production units,and the problems encountered in the accounting process were analyzed.This article concludes from the research that:1.Currently,the carbon emission accounting method used in oil and gas production was improved from the guidelines used in census method,with clear procedure based on sound theoretical formulation,but there are problems encountered during actual implementation.2.The oil and gas industry lacked accurate parameters of carbon emission factor that are applicable to specific oilfield production enterprises,therefore a case study should be initiated to conduct research on the complete process in carbon emission accounting for a typical projects.3.Currently,most publicly available data are generally calculated based on the old parameters of carbon emission factors,and is likely to exaggerate the carbon emissions of oil and gas industry in China.Existing carbon emission accounting method and procedure is rational and well structured.However,some carbon emission factors are inaccurate.It is recommended to develop carbon emission accounting technique based on typical oil and gas production process,to identify and publish more robust carbon emission factors.The results provide reference for developing carbon emission accounting standards in oil and gas production enterprises.
