RESUMO

In recent decades has increased the preoccupations related to the deterioration of socioenvironmental systems. This work allows add the interest in the search for appropriate methods of environmental accounting to help measure the sustainability. In this thesis, the methods following were applied: the Ecological Footprint, Exergy Analysis and Emergy Analysis. The basis for our calculation was the Peruvian economy taking data from year 2004 as reference. The results of the application of these methods show that the tendency of the Peruvian economy is decrease its sustainability; trend can be explained by the growing dependence of non-renewable resources, particularly fossil fuels. Although, the Peruvian sustainability is good now, a decrease of its ability to support, as this occurs, revert its current condition. At the end of this work are presented two proposals, which include concepts of Ecological Footprint and Emergy Analysis, to assess the environmental performance of a national system, which claim to be more widespread and understanding that the conventional methods.
