Abstract:The report to the 20th CPC National Congress states carbon emission peaking and carbon neutralization as an extensive and deep social transformation，and need to be carried out in an active and steady way. The report also requires to accelerate the development of the digital economy，and promote deep integration of digital economy and the real counterpart. Such important statement points out policies，principles and implementation paths towards carbon emission peaking and carbon neutralization. Despite a good start is made，carbon emission peaking and carbon neutralization will meet with a series of problems and challenges along with deeper development，especially on how to improve governance level and collaboration efficiency，where lies huge gap behind developed countries.While digital and intelligent technologies such as blockchain，Internet of Things and big data have gradually been applied in various fields relevant to carbon emission governance，the metaverse under development brings enormous potential value. Based on R&D experiences acquired while practicing digital and intelligent technologies to empower real economy，it is summarized that，with promoting data sharing and enhancing technology integration as the ultimate target，a Smart Digital Network for Carbon Emission Management （shorted as SDNCEM hereafter） need to be built，which in turn will evolve into a carbon emission governance metaverse. Meanwhile，based on SDNCEM architecture，fundamental solutions such as digitalized carbon MRV and blockchain-assisted IoT sampling are proposed and then practiced in the green supply chain context within China Mobile，generating quite good results. In future，SDNCEM’s design will be further improved and a long-term evolution plan towards metaverse will be worked out，helping achieving carbon governance targets in an active but steady pace.
