El objetivo general de la presente investigación es proporcionar las bases metodológicas de preparación del proyecto de control de emisiones con vista a una auditoria inicial para Gases de Efecto Invernadero (GEI) en una Industria del sector cemento con la finalidad de identificar el nivel de gestión de sus sistemas y procesos para el cálculo de los GEI alcance 1 y 2 así como sugerir un procedimiento de cálculo de GEI que fortalezca los procesos de reporte de las emisiones GEI. Este trabajo se basó en la ISO 14064-2, relativa a la Especificación, a nivel de proyecto, para la cuantificación, el seguimiento y la base para definir el informe de la reducción de emisiones o el aumento en las remociones de gases de efecto invernadero. Las principales variables a considerar en la validación del inventario de emisiones de GEI que se sugiere considerar en el marco de la auditoria teniendo en primer nivel; de fijar al interior de la empresa el año inicial o cero, e integrar un compendio histórico de al menos 5 años de las emisiones de GEI, estimar las emisiones por calcinación de materia prima, por uso de combustibles y producción de cemento.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The global cement industry is responsible for approximately 5% of total CO2 emissions in the world, as a result of chemical reactions in clinker production, fuel consumption, electricity use, transportation of raw materials and finished products. The general objective of this research is to provide the methodological bases for the preparation of the emission control project with a view to an initial audit for Greenhouse Gases (GHG) in a Cement industry in order to identify the management level of its systems and processes for calculating GHG scope 1 and 2 and suggest a GHG calculation procedure that strengthens the GHG emissions reporting processes. This work was based on the ISO 14064-2, regarding the Specification, at the project level, for the quantification, monitoring and the basis for defining the report of the reduction of emissions or the increase in greenhouse gas removals. The main variables to consider in the validation of the inventory of GHG emissions that are suggested will be considered in the framework of the audit taking first level; to set within the company the initial year or zero, and to integrate a historical compendium of at least 5 years of GHG emissions, to estimate emissions from calcination of raw material, by use of fuels and cement production.]]></p></abstract>
