According to reports, the world's first panoramic carbon accounting system —— "Panstone Yuheng Carbon Accounting Large Model", led by the Shanghai Institute of Advanced Technology, Chinese Academy of Sciences, was officially launched in Shanghai. This marks a major technological breakthrough for China in the field of carbon accounting, shifting from "following others" to "redefining the paradigm."

Core Breakthrough: Integration of Data, Algorithms, and Computing Power

The "Panstone Yuheng" large model aims to break through the high knowledge barriers, slow data updates, and low resolution of traditional carbon accounting, building a solid underlying support system:

Data Layer: Centered on 8 types of self-developed datasets, it has aggregated 208 TB of multi-format carbon data, achieving high-frequency updates and deep integration of data.

Algorithm Layer: Based on self-developed multi-approach accounting methodology, it drives 5 specialized intelligent agents to collaborate through a vertical large model with 3.2 billion parameters, ensuring the completeness of accounting.

Computing Power Layer: Relying on high-performance server clusters and external computing centers, it provides flexible computing power supply.

Functional Highlights: 5 Intelligent Agents "Each Playing Their Own Role"

This model is not only a conversational tool but also a "digital expert" with practical capabilities. Its 5 intelligent agents are designed for different complex scenarios:

Industrial Simulation: Achieves digital simulation and optimization of the system process.

Trade Accounting: Accurately calculates carbon transfer in international trade.

Lifecycle Assessment (LCA): Automatically completes the entire accounting process from goal setting to inventory analysis and result interpretation.

Natural Source Accounting: Accurately assesses natural carbon sinks such as forests and oceans.

Uncertainty Analysis: Provides a scientific confidence assessment for the accounting results.

Value Reassessment: Revealing the Real "Chinese Emission Reduction Contribution"

The preliminary operational results of the "Panstone Yuheng" large model are significantly enhancing China's technological voice in global climate governance:

Accounting Correction: Taking 2022 data as an example, under the new accounting system, China's greenhouse gas emissions were reduced by 17.7% compared to traditional production-side accounting results, while the US and Japan increased by 15.2% and 7.2%, respectively.

Foreign Trade Negotiation: It found that the EU's CBAM default emission factor systematically overestimates Chinese products, providing scientific basis for Chinese enterprises to cope with international carbon tariffs.

Green Contribution: Accurately calculated that the wind and photovoltaic products exported by China in 2024 contributed approximately 350 million tons of carbon reduction during their operation phase globally.

Meaning Behind the Name: Science, Wisdom, and Fairness

"Panstone": Refers to the solid foundation of scientific research.

"Yu": Originates from the wisdom of Yu the Great controlling floods, symbolizing the management of global carbon flows.

"Heng": Represents the principles of fairness and impartiality in accounting.

Conclusion: The "Chinese Answer" to Carbon Accounting

Carbon accounting is the basis of international carbon pricing. The release of "Panstone Yuheng" not only provides technical support for China to achieve its "dual carbon" goals but also contributes Chinese wisdom to promoting a more fair and scientific new order of carbon emission responsibility distribution globally.
