This paper analyzed the CO

2

emission characteristics of Nanchang and forecasted its carbon dioxide emission peak by building an IPAT model. It can be found that coal consumption was the main source of CO

2

emissions in Nanchang. Steel and power industries were the main sources of CO

2

emissions in the industrial field of Nanchang

with a relatively stable proportion. According to the current development trend of Nanchang

CO

2

emissions are expected to peak in 2024. Keeping energy intensity and CO

2

emission intensity declining will be crucial for both the construction of low-carbon city and the peak of CO

2

emissions as soon as possible in Nancha

ng. And adjusting the energy structure

increasing the proportion of clean energy

building an industrial system with low carbon emission and implementing low-carbon policies should be the key tasks of Nanchang in the future.
