The world's first panoramic carbon accounting system, the "Panshi-Yuheng Carbon Accounting Large Model," was officially launched on Tuesday in Shanghai.
Carbon accounting refers to the measuring and tracking of the greenhouse gas volumes emitted by a country or an organization. It is a key basis for meeting international climate commitments and for international carbon pricing.
Spearheaded by the Shanghai Advanced Research Institute under the Chinese Academy of Sciences, the panoramic model -- so called because it covers the production side, the consumption side, and natural sources of carbon emissions -- is designed to precisely serve China's needs in tackling climate change.
Built on the ScienceOne, or "Panshi," a scientific foundation model, the new large model uses a three-layer architecture covering data, algorithms and computing power. Its high-quality proprietary data framework has helped build a dataset system that combines internal and external datasets with multi-dimensional coverage to meet the needs for a wide range of applications, including natural-language queries, multi-database management and intelligent hybrid retrieval.
"The carbon accounting large model gives us higher efficiency and precision in carbon accounting, as well as greater spatial and temporal resolution. It provides a practical methodology and data foundation for our country's carbon trading, carbon markets, carbon tariffs, and future carbon pricing. It also solidifies the scientific basis for our national climate governance, while offering a Chinese solution to global climate governance," said Wei Wei, vice president of the Shanghai Advanced Research Institute, Chinese Academy of Sciences.
The Panshi-Yuheng model is designed to address bottlenecks in traditional carbon accounting, including high knowledge barriers, cumbersome data processing, long timeframes and low resolution. Already, it has been used to develop a high-precision holographic map of China's carbon emissions. With a high degree of accuracy, it has also calculated the emission reduction contributions of China's green products to the world, and it provides critical support for the green transition of key industries, and the country's response to international carbon policies.
