Current status and suggestions on carbon emission accounting methods for coal-to-oil projects
摘要
Abstract
Developing coal-to-oil technology is a strategic measure to ensure national energy security,and coal-to-oil projects are also one of the major sources of carbon emissions in the coal chemical industry.In the context of the"carbon peaking and carbon neutrality goals",establishing a reasonable carbon emission accounting method for coal-to-oil projects and obtaining accurate carbon emission data is the foundation for integrating the coal-to-oil industry into the national carbon trading market.It is also essential for enterprises to develop carbon reduction plans and compile sustainability and ESG(Environmental,Social and Governance)reports.Based on the current development status of China's coal-to-oil industry,the significance and value of carbon emission accounting for coal-to-oil projects were analyzed and the current methods for carbon emission accounting were summarized.Existing accounting methods in the chemical industry do not meet the requirements for the comparability of unit product emission intensity in terms of consistency in emission sources,accounting boundaries and product yield statistics.In areas such as carbon emissions from raw material consumption and thermal emissions,the accounting data does not meet the quality requirements necessary for carbon market quota allocation.To address these shortcomings,six recommendations were proposed,including the elimination of the distinction between direct and indirect liquefaction processes in accounting guidelines,exploring joint entity compliance models,selecting carbon mass balance and online continuous monitoring methods depending on the situation,applying product standardization and treatment based on low calorific value,treating externally supplied syngas as a carbon-containing output,and simplified treatment using net thermal energy consumption and default thermal carbon emission factors,aming to provide a reference for the development of carbon emission accounting guidelines and related technical standards for coal-to-oil projects.关键词
