Emergy is a term coined in the late 1970s by Howard T Odum, an American ecologist and systems theorist at the University of Florida. It is an energy accounting framework designed to measure the environmental and economic impact of certain activities. It is commonly used to assess the sustainability of various ecosystems, ranging from local communities to entire countries. Emergy seeks to measure not only the physical energy associated with different activities, but also the “embodied” energy, or energy that results from the activities needed to bring a product or service to its end user.
