Consolidating carbon sink capacity and reducing carbon pressure are important channels to achieve the carbon peaking and carbon neutrality goals actively yet prudently. In order to study the current situation of carbon pressure in the Northwestern Sichuan, we took the carbon pressure of the Aba Tibetan-Qiang autonomous prefecture (Aba prefecture) as an example and used the Intergovernmental Panel on Climate Change (IPCC) approach to measure the carbon emissions, carbon uptake, and the carbon balance index (CBI) of each county-level city in Aba prefecture from 2012 to 2020. The study found that: (a) There was a continuous trend of declining carbon emissions, increased carbon uptake, and decreased CBI in Aba prefecture during the sample period, but there is a large variability among county-level cities; (b) Aba prefecture differs in the spatiotemporal distribution of carbon emissions, carbon uptake, and CBI. Based on the research results, we propose several optimized paths for alleviating the current carbon pressure situation in the Northwestern Sichuan
