This study introduced the environmental input-output analysis and reviewed its applications in the field of industrial ecology. The core of environmental input-output analysis is the input-output model including monetary, physical, and hybrid input-output models. Major applications of environmental input-output analysis in the field of industrial ecology include environmental pressure accounting, life cycle assessment, analysis of relative contributions of socioeconomic factors, critical supply chain path analysis, risk impact analysis, and environmental network analysis. Moreover, scholars began to develop environmental input-output databases to provide convenient and standardized data sources for environmental input-output studies. Finally, this study discussed several potential development trends of environmental input-output analysis.
