Abstract: In October 2024, the National Development and Reform Commission (NDRC) and other departments released the “Work Plan for Improving the Carbon Emission Statistics and Accounting System”, which explicitly proposed the promotion of municipal-level energy balance tables and the development of carbon emission prediction and early warning models. Currently, China has not yet released municipal-level energy balance tables, making it impossible to directly estimate municipal carbon emissions using the IPCC inventory-based method. This paper draws on the electricity–energy–carbon model at the industry level and conducts high-frequency carbon emission estimation for 14 municipalities in Guangxi as a case study. Based on this, the Prophet model is introduced, incorporating planned electricity consumption data to construct a carbon emission prediction and early warning model, enabling long-term carbon emission forecasting at the municipal level. The results indicate the following: First, among the 14 municipalities in Guangxi, Baise has the highest share of carbon emissions (27%), followed by Liuzhou (13%). In terms of carbon emission intensity, six municipalities exceed the regional average, including Baise, Chongzuo, and Fangchenggang. Second, the total carbon emissions in Guangxi (from energy consumption) are expected to peak by 2030, and all 14 municipalities are expected to achieve peak carbon emissions from energy consumption before 2030.
