The Journal of Environment & Development, Available online 23 May 20251070-4965https://doi.org/10.1177/10704965251345509https://dspace.lib.cranfield.ac.uk/handle/1826/24172Cement production in China suffers from low eco-efficiency due to high coal and electricity consumption and substantial emissions. This study proposes a novel approach integrating Life Cycle Assessment (LCA) and Material Flow Cost Accounting (MFCA) to improve both economic and environmental performance. The method includes: (1) quantifying material, economic, and environmental losses using LCA and MFCA; (2) identifying improvement strategies through Pareto analysis, hypothesis testing, and expert input; and (3) validating results using an empirical case study. Applied to a cement company in Xinjiang, the approach increased eco-efficiency from 0.8737 to 1.0519, demonstrating synchronous economic and environmental gains. This is one of the first studies to apply LCA–MFCA integration in China’s cement sector.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/eco-efficiencymaterial flow cost accountinglife cycle assessmentcement industry4104 Environmental Management33 Built Environment and Design38 Economics40 Engineering41 Environmental Sciences4005 Civil Engineering3302 Building12 Responsible Consumption and ProductionDevelopment StudiesArticle1552-5465673382
