Carbon management technology is an important pillar for achieving the temperature control targets of the Paris Agreement anda key component of China's technology portfolio for achieving its carbon neutrality goals. Currently,as the demand for negative emissionsincreases globally,Carbon management will play an indispensable role in proactively managing carbon dioxide emissions from existingplants and facilities,hard-to-reduce sectors,and atmospheric legacy,but there are still some ambiguities and deficiencies in the currentscientific understanding and cutting-edge advances in the field of carbon management. This paper provides an in-depth analysis of theconnotation and extension of carbon management,technological segmentation,global cutting-edge progress,comparison of developmenttrends between China and the United States,and issues and recommendations. The study summarizes the definition and significance ofcarbon management,technology system and carbon cycle model; discusses the breakdown of natural carbon management,active carbonmanagement, carbon capture, utilization and sequestration (CCUS) and carbon removal (CDR) technologies; summarizes thecurrent progress of global carbon management frontiers in terms of scientific consensus,technological development and internationalcooperation; and compares the development of carbon management in China and the United States in terms of emission reductiondemand,technological tracking,support policies,and market investment. Finally,the study proposes corresponding measures in terms ofscientific and technological research and development,policy incentives,infrastructure,and bilateral and multilateral cooperation. Thisresearch systematizes the global carbon management development and technological frontiers, provides reference for the advanced deployment of China's carbon management strategic technology system and the achievement of carbon neutrality goals under the orderlyand stable transformation of the energy system.
