Research on China's Transportation Carbon Measurement Technical Specification System based on Hall Three-Dimensional Structure and Entropy Weight-TOPSIS Method

Abstract

Carbon measurement is the core foundation for the transportation industry to achieve green and low-carbon development. China has not yet established a unified technical specification system in the field of transportation carbon measurement, with key challenges including insufficient equipment adaptability, lack of traceability specifications, and unclear formulation priorities. To address these issues, this study integrates the Hall Three-Dimensional Structure, Entropy Weight Method, and TOPSIS Method to construct a systematic and practical transportation carbon measurement technical specification system. Firstly, it analyzes the current status and development trends of transportation carbon measurement; secondly, it builds the system framework based on the Hall Three-Dimensional Structure and divides it into five core modules; finally, it determines the module weights through the Entropy Weight Method and completes the prioritization ranking of 25 types of technical specifications using the TOPSIS Method. This research fills the gap in the construction of transportation carbon measurement systems and provides scientific guidance for the formulation and revision of industry specifications.
