Investigating how urban land use change affect carbon storage provides notable practical implications for orderly regional urban expansion and sustainable development. However, current research exhibits inconsistencies in assessing how urban expansion patterns affect carbon storage. This study therefore takes China's Yangtze River Delta (YRD) urban agglomeration as a case study. It quantifies regional changes in urban expansion (quantity, intensity, and patterns) and carbon storage, while conducting a multi-scale analysis of urban expansion's impacts on carbon storage. Findings that from 2000 to 2022, the urban land in the region expanded by 15,196.24 km 2 , resulting in a reduction of 4.07 × 10 7 Mg in carbon storage, and the reduction intensity continued to increase, the impact of medium cities was the most significant among them. In terms of expansion patterns, although edge-expansion was dominant (contributing 73.41% of the losses), its impact was slowing down; leapfrog expansion showed an increasing trend, and its impact intensity was the highest (1.09 and 1.12 times that of edge-expansion and infilling expansion respectively). In terms of expansion intensity, medium-speed expansion zones had the highest contribution rate (57.07%) and the greatest intensity to the loss of carbon storage, but the trend had shown a slowdown. We recommend that the YRD urban agglomeration thoroughly implement China's 14th Five-Year Plan, prioritize infilling expansion, and strictly control leapfrog expansion—in particular, in those small and medium-sized cities, the impacts are growing steadily—to promote low-carbon, sustainable development across the region.
