The National Greenhouse Gas Accounting Guidelines (2019 Revised Edition) issued by the IPCC, the "Corporate Accounting and Reporting Standards" jointly established by WRI and WBCSD, and the ISO14064-based standards have established reporting and verification standards for corporate greenhouse gas emissions and removals, and proposed to clarify corporate emission sources from the scope of direct emissions, indirect emissions from electricity, and other indirect emissions. By collecting data, selecting emission factors, and applying calculation tools to summarize corporate greenhouse gas emission data, it provides a reference for corporate carbon verification, carbon trading, and carbon emission reduction.

At present, the Chinese invention with application number 202310417086.7 discloses a blockchain-based carbon asset trading method and system, including the competent authority calculating the quota base amount of carbon emissions this year, and issuing the first token corresponding to the carbon emission quota on the blockchain based on the quota base amount, and directly transferring the first token to the virtual account of each key emission unit; the competent authority predicts the excess amount of carbon emissions this year.
