Abstract Sludge ceramsite and fly ash ceramsite are the two most common types of solid waste ceramsite. To compare and analyze the carbon footprint characteristics of the two types of solid waste ceramsite and quantitatively evaluate the carbon reduction benefits of the products, a carbon footprint accounting model for sludge ceramsite and fly ash ceramsite is constructed from the perspective of carbon footprint. Based on sensitivity analysis, key emission reduction factors are identified, and the carbon reduction potential of sludge ceramsite and fly ash ceramsite is predicted and evaluated through scenario analysis. Meanwhile, using error propagation equations for uncertainty analysis ensures the reliability and effectiveness of carbon footprint results. The results showed that the CO2 emissions from the production of 1kg sludge ceramsite and 1kg fly ash ceramsite were 1.00 and 0.58 kg, respectively. The carbon footprint characteristics of sludge ceramsite and fly ash ceramsite were similar, and the ceramsite production stage was the main link in the carbon emissions of the two ceramsite particle products, accounting for 93.71% and 89.12% of their respective carbon footprints (excluding the raw material acquisition stage), respectively. The raw material structure is the most sensitive factor affecting the carbon footprint of sludge ceramsite and fly ash ceramsite, followed by the transportation structure. Compared with sludge ceramsite, the carbon footprint of fly ash ceramsite is more affected by the adjustment of raw material structure. In the scenario of collaborative optimization, the carbon emission reduction potential of simultaneously optimizing transportation and raw material structure (31%~78%) is far higher than that of simultaneously optimizing transportation and power structure (2%~5%). In addition, the emission reduction potential of the three factors acting simultaneously is the highest, reaching 33%~79%.
