93 p.Introducci?n: La evaluaci?n de las emisiones de gases de efecto invernadero (GEI) en los hogares urbanos permite mostrar los patrones de variaci?n, seg?n el consumo de energ?a y el uso de productos derivados de los combustibles f?siles. Objetivo: evaluar la relaci?n entre las emisiones derivadas del uso de combustibles f?siles y el recurso energ?tico junto a las caracter?sticas socioecon?micas y sociodemogr?ficas en hogares del municipio de Ibagu?. Metodolog?a: Se realiz? una encuesta semi-estructurada, aplicando un muestreo aleatorio doblemente estratificado, seg?n el estrato socioecon?mico (1-6) y las comunas de la ciudad (13), con un 95% de confianza. Se registraron algunas caracter?sticas sociodemogr?ficas, de la vivienda, del consumo de las fuentes de energ?a, el medio de transporte y el combustible utilizado. La cantidad de emisiones se estim? seg?n la actividad, mediante los factores de conversi?n. Se aplic? estad?stica descriptiva e inferencial para encontrar la asociaci?n de caracter?sticas del hogar con sus emisiones y correlaci?n, empleando el programa SPSS. Resultados: Se encontr? que los hogares de Ibagu? emiten un total de 169,2 Gg CO2/a?o, disgregado en el uso de gas natural domiciliario que emite anualmente 87,0 Gg CO2, seguido de las 48,8 Gg CO2 que produce el transporte y en menor cantidad las emisiones derivadas del consumo de energ?a el?ctrica y gas licuado de petr?leo (GLP) con 33,2 y 0,2 Gg CO2/a?o, respectivamente. Se detect? una correlaci?n positiva entre las emisiones totales de los hogares con el ingreso mensual, estrato socioecon?mico y el n?mero de integrantes del hogar. Conclusiones: El consumo y las emisiones derivadas de combustibles f?siles y energ?a el?ctrica en el sector residencial de Ibagu? es l?nea base para la planificaci?n responsable de la mitigaci?n del cambio clim?tico que incluya la modificaci?n de h?bitos de consumo, enfoque de una matriz energ?tica sostenible y una evaluaci?n de impacto ambiental como instrumento de planificaci?n urbana.Introduction: The evaluation of greenhouse gas (GHG) emissions in urban households shows the patterns of variation, according to energy consumption and the use of products derived from fossil fuels. Objective: to evaluate the relationship between the emissions derived from the use of fossil fuels and the energy resource, together with the socioeconomic and sociodemographic characteristics of households in the municipality of Ibagu?. Methodology: A semi-structured survey was carried out, applying a double stratified random sampling, according to the socioeconomic stratum (1-6) and the communes of the city (13), with 95% confidence. Some sociodemographic characteristics of housing; the consumption of energy sources; the means of transport and the fuel used were recorded. The amount of emissions was estimated according to the activity, using the conversion factors. Descriptive and inferential statistics were applied to find the association of household characteristics with their emissions and correlation, using the SPSS program. Results: It was found that Ibagu? households emit a total of 169.2 Gg CO2/year, given by the use of household natural gas that emits 87.0 Gg CO2 annually, followed by the 48.8 Gg CO2 produced by transportation and to a lesser extent the emissions derived from the consumption of electric energy and liquefied petroleum gas (LPG) with 33.2 and 0.2 Gg CO2/year, respectively. A positive correlation was detected between total household emissions with monthly income, socioeconomic status, and the number of household members. Conclusions: The consumption and emissions derived from fossil fuels and electrical energy in the residential sector of Ibagu? is the baseline for responsible planning for the mitigation of climate change that includes the modification of consumption habits, an approach to a sustainable energy matrix and a environmental impact assessment as an urban planning instrument.
