Information for Researchers and LCA Practitioners
The EIO-LCA method is one option for performing input-output life cycle assessment. Unlike process-based LCA methods which focus on examining a single process in detail, input-output-based LCA methods consider an entire economy - all activities of all industry sectors. In that way, the boundary for input-output life cycle analyses are very broad. The trade-off is that input-ouput-based LCA methods are based on industry sectors and thus lacks the specificity of process-based models.
The Economic Input-Output Life Cycle Assessment method uses economic input-output tables as the basis for analysis. These tables, typically produced by national governments, quantifiy the economic purchases between different industry sectors. In addition, national-level data on material or energy resources consumed by industry sectors, and data on industry releases to the environment are used to estimated life cycle impacts.
