The system factors in both production and consumption, lessening the responsibility of exporters such as China

Meanwhile, it raised the total for the United States by 15.2 per cent.
“Panoramic carbon accounting is set to become a core driver for advancing global climate governance towards greater precision and consensus,” CAS said on April 8.
The ScienceOne-Yuheng Carbon Accounting Large Model would contribute to the establishment of “a more equitable and scientifically grounded global carbon accounting and responsibility-sharing framework”, CAS added.
Wei Wei, vice-president of the institute and the lead scientist of the model’s research team, was quoted as saying that the model “represents a paradigm shift in how we understand and manage global carbon emissions”.
