The monitoring of greenhouse gas (GHG) is the important supports for achieving China’s target of peak carbon emission and zerocarbon. This paper summarized the GHG monitoring standards form World Meteorological Organization, China Meteorological Administration and Ministry of Ecological Environment, reviewed the major GHG measurement technologies including the nondispersive infrared method, gas chromatography, optical cavity ringdown spectroscopy, offaxis cavity integral system. The principles, the advantages and disadvantages of the methods were analyzed, the suitable application scenarios of different methods were proposed, the importance of sampling and calibration system was highlighted, the development of GHG measurement technology was forecasted. It is expected to provide reference and support for China’s greenhouse gas monitoring network.
