Tetrafluoromethane (CF_4) is one of the typical non-carbon dioxide gases with super strong greenhouse effects, legally regulated by Kyoto Protocol. CF_4 emissions continue to increase with the continuous expansion of industrial activities such as aluminum electrolysis and semiconductor, resulting in the aggravation of global climate change and deterioration of environment on which human survival depends, as well as the hindering of the sustainable development of related industries. Intensifying the control of non-carbon dioxide greenhouse gases such as CF_4 is an important part of China's "carbon peaking and carbon neutrality goals" strategic objectives with the implementation of the action plan. Firstly, the sources of CF_4 are analyzed systematically, and the main industry sources, emission characteristics and generation mechanism of CF_4 are expounded in this paper. Then, the limitation of source emission reduction of CF_4 and the inevitable trend of pipe-end treatment are emphatically analyzed after summarizing the status of source emission reduction measures of CF_4. As for the end treatment of CF_4, seven pipe-end treatment technologies, including deep-cooling separation, adsorption, membrane separation, thermal combustion, thermal catalytic decomposition, plasma high-energy decomposition and electrocatalytic decomposition, are summarized from the perspective of physical and chemical treatment. Meanwhile, the basic principles, application cases and development status of relevant methods are described. Some parameters such as temperature, decomposition product, energy consumption, as well as the advantages and disadvantages of each technology are compared and analyzed. In the final, the future challenges of CF_4 pipe-end treatment technology are predicted and evaluated based on the industry requirements and application scenarios.
