Reducing carbon emissions is fundamental to achieving carbon neutrality. Existing studies have typically estimated emissions by predicting fossil fuel consumption across sectors under different socioeconomic scenarios; however, uncertainties in future development often lead to deviations from these assumptions. To address this limitation, this study proposes a data-driven approach for evaluating national carbon emissions using historical data. Countries with similar energy consumption patterns were selected as reference samples, and their emission pathways were analyzed to predict future emissions for countries that have not yet reached their peak. Key indicators, including peak levels, timing, plateau duration, and post-peak decline rates, were identified. The results indicate that the trends in unpeaked economies can be effectively assessed based on the emission patterns of countries with comparable energy structures. Applying this framework to China suggests a carbon peak between 2027 and 2030, in the range of 14.207 to 16.234 Gt, followed by a gradual decline from 2031 to 2036. Compared with the average results of the existing studies, the predicted minimum and maximum emissions show error margins of 10.1% and 1.41%, respectively. This study proposes a top-down methodology that provides a transparent, reproducible, and empirical framework for forecasting carbon emission pathways, thereby offering a scientific basis for assessing countries that have not yet reached their emissions peak.
