The urban CO2 emission peak judgment model based on the conditional judgment function and Mann-Kendall trend analysis test method was constructed to analyze their direct CO2 emissions and total CO2 emissions characteristics in the 36 typical large cities of China from 2005 to 2019, and determine whether the comprehensive CO2 emissions of each city have reached its peaks. In-depth analysis on the characteristics of typical cities at different emission stages was also conducted. The results show that among the 36 typical large cities, Kunming, Shenzhen and Wuhan have reached their peaks, 8 cities are in the plateau period, and the remaining 25 cities have not reached their peaks comprehensively. It is recommended that cities that have not reached the peak of CO2 emissions should learn the experience from the city that have reached the peak according to their own characteristics, such as adjusting the industrial structure and energy structure, reducing the intensity of carbon emissions, and strengthening the decoupling of carbon emissions from economic growth, so as to achieve the peak of carbon dioxide emissions as soon as possible.

Key words: Peak, Typical cities, CO2 emission, Mann-Kendall trend test
