Analysis of Carbon Emission Peaking Status of the Guangdong-Hong Kong-Macao Greater Bay Area and Hangzhou Bay Greater Bay Area
This study took the Guangdong-Hong Kong-Macao Greater Bay Area(GHM)and Hangzhou Bay Greater Bay Area(HZB)and the included cities as the research objects,in the inspection period 2011 to 2020,and evaluated the carbon peak status of the bay area and cities via condition judgment and Mann-Kendall trend test analysis.Carbon emissions analysis demonstrated that GHM showed an upward trend,while HZB showed a two-stage upward and downward trend,and the emissions and trends of different cities varied significantly.The carbon intensity analysis suggested that,HZB was significantly higher than GHM,and these two bay areas and most cities displayed a clear downward trend.Carbon emissions in these two bay areas and most cities significantly reduced or rebounded in 2020.Mann-Kendall trend test analysis showed that,these two bay areas and most cities have not yet confirmed carbon emission peak.
