 Environmentally extended input output, EEO, analysis is a powerful tool for understanding how economic activity affects the environment. It can be used to identify the sources of environmental pollution and quantify their effects on the environment. By examining the flow of materials and energy through an economy, EIO can provide insights into the environmental consequences of production and consumption decisions. EEO also allows us to understand the interconnectedness of different countries' economies and the environmental implications of international trade. This article was authored by Justin Kitzas.
