Abstract: There are still some problems in the process of control and reduction of greenhouse gas emissions, energy green transformation, industrial low-carbon upgrading, ecological environment management and control, technology and management innovation in China. These problemes include limited implementation means of carbon measurement, difficulty in obtaining accurate, reliable and complete carbon data, and insufficient application of carbon data to guide pollution reduction and carbon reduction. Therefore, the characteristic connotation of carbon peaking and carbon neutrality was briefly described, and the research progress of "dual carbon" at home and abroad was reviewed. Meanwhile, the connotation of carbon metering and its shortages in China were sorted out. On this basis, the typical demand scenarios of carbon metering to support the control and reduction of carbon emissions were discussed and analyzed. Besides, the carbon metering path was put forward to serve low-carbon development, and ideas were recommended to improve the carbon metering system, so as to scientifically and efficiently complete the work on domestic carbon metering, further to facilitate the implementation of "dual carbon" strategy.
