Mensuração e evidenciação dos créditos de carbono utilizando um modelo quantitativo parcimonioso: um estudo de caso na Granja Paraíso.

Abstract

This research proposes to measure and show the carbon credits in pig farming activity of Granja Paraíso based on AMS-III models. D Version 14 used in the methodology of Clean Development Mechanisms (CDM) and the model Duarte and Vieira (2014), developed for the same purpose. In Brazil, pig farming has become one of the main activities responsible for the emission of greenhouse gases in the atmosphere. Thus, it is notorious, that investments in technology in this activity are required to reduce emissions of greenhouse gases (GHG) and maximize the efficiency of the anaerobic digestion process. This issue is very important and should be analyzed and diagnosed using mathematical models that fits local pig farming, in order to make accurate estimates of the amounts of CO2 in the atmosphere that were avoided. Based on this reality, was made analyzes the quantitative models selected in order to ensure its efficiency and effectiveness in generating information about carbon credits, in order to, in the end, highlight the environmental generated and not accounted revenues and not accounted by the company already cited. Before the results, we see that the estimates of carbon credits instigate the need to assess the AMS-III model. D, version 14 of the Project Design Document (PDD) for the treatment of swine waste, because it considers some parameters that does not represent the local reality. So, the Duarte and Vieira (2014) model, which considers parameters that represent the local situation with the least amount of possible variables in the measurement of carbon credits, is considered as accurate and parsimonious. Comparing the estimated results of the Certified Emission Reductions (CERs) it is observed that the model determined by the Framework Convention of the United Nations on Climate Change (UNFCCC) overestimates the amount of carbon credits for small pigs, because the data of average weights patterns do not represent the reality of the company cited above.
