Description

Technical Field

[0001] The present invention relates to a carbon emission accounting method, system, device and storage medium, and in particular to a park carbon emission accounting method, system, device and storage medium, belonging to the technical field of carbon emission accounting. Background Art

[0002] In the past few decades, the urbanization process has accelerated, and various types of industry and commerce have developed rapidly. As the main battlefield of manufacturing power and an important source of greenhouse gas emissions, the industrial park currently still has problems such as unclear carbon emission base, environmental capacity close to the limit, differences in industrial structure and carbon emission structure, and the need to establish a statistical accounting system for carbon emission data. Relying on different types and characteristics of industrial parks, focusing on relevant factor resources, and through differentiated, refined, and precise research on carbon emission accounting models, it is expected to become a new breakthrough point for achieving energy conservation and carbon reduction in industrial parks. The carbon emission accounting method directly affects the assessment of the carbon emission level of the industrial park and is the basis for formulating an effective carbon emission reduction strategy. Therefore, research on the carbon emission accounting model of the industrial park is very necessary for promoting effective energy conservation and emission reduction measures.

[0003] The existing technologies for carbon emission accounting in industrial parks have the following deficiencies: insufficient attention is paid to the demarcation of accounting boundaries, some accounting contents overlap or are omitted; the calculation method of emission sources is not standardized, resulting in insufficient accounting accuracy. Carbon accounting research for industrial parks only stays on the direct carbon emissions generated by energy consumption within the park, and does not include park emission reduction items (carbon sinks, renewable energy) in the park's carbon emission accounting. The currently used carbon emission methods require too many parameters and require the collection of a large amount of data in the early stage. The workload is huge and prone to errors, making it difficult to apply in engineering. Summary of the invention
