Historically, questions related to environmental policy have been difficult to solve, because solutions depend on accurately balancing the needs of both human and natural systems. In addition, there has been no good way to express the socioeconomic and environmental effects of policies in common terms. a knowledge gap exists in our ability to assess the effects of environmental policies using a comprehensive, integrated approach. Assessment methods that can bridge this gap are needed to address complex issues of environmental policy. Based on past studies, environmental accounting using emergy was identified as a method that had been used by some scientists to bridge the gap. This paper provides a guide to Emergy Analysis methods with particular emphasis on those methods used to characterize a state within the larger context of its region and the nation
