Abstract:Purpose: With the increasing number of large-scale open-pit mining construction projects, the high energy consumption and high carbon emissions of mines have received high attention from all sectors of society. In order to scientifically and accurately evaluate and control greenhouse gas emissions from mines, it is urgent to develop a set of carbon emission accounting methods suitable for open-pit mines. Method: Using literature research, statistical analysis, and applicability analysis methods, this study focuses on comprehensively evaluating the basic principles, application scope, advantages, and disadvantages of five major carbon emission accounting methods: IPCC inventory factor method, life cycle assessment method, input-output method, material balance method, and measured method. It also discusses these methods in combination with domestic and international cases of carbon emission accounting for mines. Result: Through comparative analysis, it was found that the IPCC inventory factor method and life cycle assessment method have unique advantages in data acquisition and on-site operation. The input-output method and material balance method have high accuracy in accounting, and the measured method has the highest accuracy in small-scale areas. Conclusion: The mine should consider the characteristics of various accounting methods comprehensively based on the actual situation to conduct carbon emission accounting. The comprehensive evaluation of five accounting methods in this article provides some reference value for open-pit mines to choose appropriate carbon emission accounting methods.
