Economic Input-Output Models for Environmental Life-Cycle Assessment
Process and product models are commonly used for performing life-cycle assessments (LCAs) of the environmental impacts of materials and products through different stages of fabrication, use, and end-of-life options. In this article, we show that these models can be represented as process flow diagrams or as matrices of process interactions. In either representation, the inventory of environment...
متن کاملIdentification of Economic Cluster with Information Gain Method, based on Input-Output Tables
In this paper, we propose a more flexible “economic cluster identification” approach to analyzing the domestic I/O flows of intermediary goods and service that is based on information theory. Using an “information gain” estimation method, we make efficient use of inequality constraints about the structure of the domestic I/O flows. In particular, it allows us to impose a set of less restriction...
متن کاملA mixed-unit input-output model for environmental life-cycle assessment and material flow analysis.
Materials flow analysis models have traditionally been used to track the production, use, and consumption of materials. Economic input-output modeling has been used for environmental systems analysis, with a primary benefit being the capability to estimate direct and indirect economic and environmental impacts across the entire supply chain of production in an economy. We combine these two type...
متن کاملProduct Environmental Life-Cycle Assessment Using Input-Output Techniques
Life-cycle assessment (LCA) facilitates a systems view in environmental evaluation of products, materials, and processes. Life-cycle assessment attempts to quantify environmental burdens over the entire life-cycle of a product from raw material extraction, manufacturing, and use to ultimate disposal. However, current methods for LCA suffer from problems of subjective boundary definition, inflex...
متن کاملExtending the Boundaries of Life-Cycle Assessment through Environmental Economic Input-Output Models
Life-cycle assessment (LCA) is a cornerstone of current practice in industrial ecology, linking the product life cycle, from design to disposition, with the environmental impacts generated at each stage. It is one of the ways that industrial ecology brings a systems approach to environmental analysis. LCA aids environmental improvement by revealing the complete impact of a product, rather than ...
